Process theory

Process theory is a type of scientific explanation that describes how and why an entity—such as an organization, social structure, or phenomenon—changes and develops over time through a sequence of events, activities, and mechanisms.^[1] Unlike variance theories, which focus on identifying causal relationships between variables to explain differences or outcomes (e.g., why some organizations perform better than others based on specific factors), process theories emphasize the temporal unfolding and interconnected steps that generate change.^[1] Originating in the social sciences, particularly in fields like sociology and management, process theory provides a framework for understanding dynamic phenomena such as organizational evolution, social movements, and policy implementation.^[1] It has been applied across disciplines to model complex, non-linear developments, highlighting the role of interactions, contingencies, and emergent properties rather than static attributes. Key contributions include typologies of change processes, which inform research in areas like innovation, adaptation, and transformation.

Fundamentals

Definition and Scope

A process theory is a system of ideas that explains how and why an entity—such as an individual, organization, or society—changes and develops over time through sequences of events, interactions, and mechanisms. This approach identifies the generative forces and contingencies that produce change events, treating development as a dynamic progression rather than isolated outcomes.^[2] The scope of process theory extends to dynamic phenomena such as evolution, adaptation, and transformation, with a primary emphasis on temporal sequences over static states or equilibrium conditions. It finds broad applicability in the social sciences and management, where it elucidates the unfolding of organizational and societal structures, as well as in psychology, which applies it to behavioral and cognitive developments, and philosophy, particularly in traditions viewing reality through ongoing becoming.^[2]^[3] Central to process theory are key concepts that reframe entities as ongoing processes rather than fixed objects, emphasizing their emergence and persistence through temporal flows.^[3] Mechanisms of change include feedback loops, which sustain or disrupt patterns via reinforcing or balancing interactions; contingencies, which account for contextual conditions influencing outcomes; and trajectories, which trace the directional paths of development amid variability.^[2]^[3] Unlike variance theories, process theories focus on the sequential "how" of change rather than correlational explanations between variables.

Variance vs. Process Theories

Variance theories seek to explain differences or variations between entities, such as organizations or individuals, at a single point in time by identifying independent variables that predict or account for outcomes.^[4] These theories operate under a static framework, often employing correlational methods like regression models to establish causal links where specific factors (e.g., resource allocation) directly influence results (e.g., performance levels).^[5] For instance, a variance theory might posit that higher levels of employee training (X) lead to greater productivity (Y), treating the relationship as contemporaneous and equilibrium-based.^[6] In contrast, process theories explain sequences of change over time, emphasizing how events unfold through interconnected mechanisms and contingencies rather than isolated variables.^[4] They focus on dynamic narratives, such as how an initial event (A) triggers subsequent developments (B) under specific conditions (C), thereby illuminating the temporal pathways of transformation.^[5] An example is describing organizational adaptation to technological disruption as a series of iterative adjustments involving stakeholder interactions, rather than a one-time causal effect.^[6] The distinctions between these approaches are rooted in their epistemological foundations, methods, and the types of questions they address, as outlined in the following comparison:

Aspect	Variance Theories	Process Theories
Assumptions	Static relationships; outcomes result from equilibrium states influenced by external variables at a given moment.^[4]	Dynamic and emergent; change arises from evolving interactions and sequences over time.^[5]
Methods	Correlational and statistical (e.g., regression, variance analysis) to test predictive relationships.^[6]	Sequential and narrative (e.g., event sequencing, case studies) to trace causal mechanisms.^[4]
Questions Addressed	Why do differences exist between cases (e.g., what factors predict variation in outcomes)?^[5]	How does change occur and unfold (e.g., what sequences lead from one state to another)?^[6]

Process theories are particularly advantageous for analyzing complex, non-linear phenomena where outcomes emerge unpredictably from ongoing processes, such as innovation diffusion or cultural shifts, whereas variance theories excel in predictive scenarios assuming stable conditions, like resource optimization in steady-state environments.^[4] This complementarity highlights the need for selecting the appropriate paradigm based on the research context, with process approaches offering deeper insights into temporality that variance models often overlook.^[5]

Historical Development

The roots of process theory in the social sciences trace back to ancient process philosophy, particularly Heraclitus's doctrine of flux, which posited that reality is in perpetual change and that stability is illusory. This idea of constant transformation influenced later philosophical traditions and was adapted in the social sciences to conceptualize societies as dynamic entities rather than static structures. For instance, Heraclitean flux provided a foundational metaphor for understanding social change as an ongoing process of becoming, emphasizing the interdependence of opposites and the impermanence of social forms.^[7] Building on this, Hegel's dialectics further shaped process-oriented thinking by framing social development as a progression through contradictions, where thesis and antithesis resolve into synthesis, driving historical and societal evolution. In sociology, this dialectical approach was applied to analyze social institutions and norms as evolving through internal conflicts and resolutions, influencing early 20th-century theorists to view social processes as inherently progressive yet tension-filled. Meanwhile, in sociology and anthropology, Émile Durkheim's work on social evolution exemplified the adaptation of process ideas to empirical studies of change. In The Division of Labor in Society (1893), Durkheim described societal transformation from mechanical to organic solidarity as a gradual process driven by population growth, technological advances, and increasing moral density, which fostered specialization and interdependence rather than mere aggregation of individuals.^[8]^[9] By the mid-20th century, these philosophical roots integrated into organizational sociology through Richard Cyert and James March's A Behavioral Theory of the Firm (1963), which highlighted decision-making as adaptive processes shaped by routines, coalitions, and problemistic search mechanisms. This theory shifted focus from equilibrium models to how firms evolve through learning, goal adjustment, and sequential attention to uncertainties, portraying organizations as dynamic systems responsive to environmental pressures. Concurrently, systems theory and cybernetics profoundly influenced social sciences by conceptualizing societies as self-regulating, dynamic processes involving feedback loops and communication. Originating in the 1940s with Norbert Wiener's Cybernetics (1948) and Ludwig von Bertalanffy's general systems theory (1950s), these frameworks encouraged viewing social structures as interconnected wholes undergoing continuous adaptation, impacting fields like sociology and political science by emphasizing holistic, processual analyses over isolated variables.^[10]^[11] Prior to the formalization of process theory in the 1980s, social scientists in political science and economics relied heavily on qualitative narratives to depict change, tracing causal sequences through historical case studies and interpretive accounts of institutional development. In political science, scholars employed process-tracing narratives to explain policy shifts and regime transitions as unfolding events influenced by contingent interactions, as seen in mid-century works on comparative politics. Similarly, in economics, qualitative approaches examined evolutionary paths of markets and institutions through detailed historical reconstructions, contrasting with contemporaneous variance-based models that prioritized correlational explanations.^[12]^[13]

Key Publications and Scholars

Lawrence B. Mohr's 1982 book, Explaining Organizational Behavior: The Limits and Possibilities of Theory and Research, marked a pivotal moment in the formalization of process theory by providing the first explicit distinction between process and variance models in organizational analysis.^[4] Mohr argued that process models are particularly suited to explaining outcomes in dynamic, non-equilibrium contexts where sequences of events and contingent factors play a central role, contrasting them with variance models that emphasize correlational causation.^[14] Building on this foundation, key scholars advanced process theory through focused examinations of developmental dynamics. Andrew H. Van de Ven and Marshall Scott Poole's 1995 article, "Explaining Development and Change in Organizations," introduced four archetypal process theories—life cycle, teleological, dialectical, and evolutionary—as building blocks for understanding organizational change, emphasizing the role of developmental processes in generating temporal sequences of events.^[15] Ann Langley contributed significantly with her 1999 work, "Strategies for Theorizing from Process Data," which outlined analytical approaches for deriving theoretical insights from longitudinal qualitative data, and her 2007 essay, "Process Thinking in Strategic Organization," which advocated integrating process perspectives into strategy research to capture ongoing enactment and temporality.^[16]^[17] Karl E. Weick's seminal contributions, particularly in Sensemaking in Organizations (1995), framed sensemaking as a core process through which individuals and groups retrospectively construct meaning from ambiguous situations, highlighting its ongoing, iterative nature in organizational contexts.^[18] Influential publications further solidified methodological and sociological extensions of process theory. The edited volume Longitudinal Field Research Methods: Studying Processes of Organizational Change by Andrew H. Van de Ven, George P. Huber, and others (1995) provided practical guidance on designing and conducting studies that track processes over time, addressing challenges in data collection and analysis for dynamic phenomena.^[19] Andrew Abbott's 2001 book, Time Matters: On Theory and Method, extended processual thinking to broader social structures by critiquing static methodologies and advocating for theories that incorporate temporal rhythms, durations, and contingencies in sociological explanation.^[20] In the 2000s, process theory evolved from primarily descriptive accounts toward more generative frameworks that actively explain how changes emerge through the interplay of temporality and agency.^[21] This shift emphasized not just chronicling events but modeling the generative mechanisms—such as actor interactions and temporal structures—that produce social and organizational outcomes, as seen in integrative reviews that unveiled the ontological assumptions underlying process studies.^[21] Building on this, the 2020s have seen further advancements, including the integration of computational process theories to model complex organizational phenomena and enhanced use of case research to refine theoretical propositions, as of 2024.^[22]^[23]

Archetypes of Process Theories

Evolutionary Archetype

The evolutionary archetype in process theory posits that change emerges at the population level through a Darwinian-like mechanism involving blind variation, environmental selection, and retention of viable traits. Unlike goal-directed models, this archetype views development as undirected and probabilistic, where novelty arises from random differences among entities in a population, and only those variants best suited to their context persist over time. Path dependence concepts, involving historical contingencies and self-reinforcing mechanisms, are often integrated here to explain how selected traits become locked in over time.^[1]^[24] At its core, the mechanism operates in three interconnected stages: variation generates diverse, often unpredictable differences within a population; selection imposes environmental pressures that favor the survival and reproduction of fitter variants; and retention stabilizes successful traits through mechanisms like inertia or institutionalization, ensuring their propagation across generations. This cycle drives cumulative change without foresight or intentionality, emphasizing adaptation through trial-and-error rather than planned progression. The focus remains on aggregate population dynamics, such as shifts in organizational forms or idea pools, rather than individual trajectories. Key elements include its non-teleological nature, where outcomes lack predetermined endpoints, and its application to non-biological domains, such as the evolution of cultural memes—ideas that replicate and compete like genes—or organizational populations adapting to market pressures. For instance, biological evolution principles extend to conceptual realms, where random mutations in knowledge or routines undergo selection based on utility. Concepts like path dependence highlight how early events can lead to lock-ins, as in the persistence of the QWERTY keyboard layout due to increasing returns, despite alternatives.^[24] Theoretical foundations trace to Donald T. Campbell's blind variation and selective retention (BVSR) framework, which applies evolutionary logic to creative thought and knowledge processes, positing that innovation stems from generating numerous unguided ideas followed by rigorous testing. This was extended in organizational contexts by James G. March's models of learning, where exploration produces variants and exploitation retains effective routines amid uncertainty. Van de Ven and Poole (1995) incorporate path dependence elements into this archetype to account for historical influences on selection and retention. A primary strength of the evolutionary archetype lies in its ability to explain innovation and long-term adaptation without requiring anticipatory intelligence, providing a robust lens for understanding emergent complexity in dynamic environments.

Teleological Archetype

The teleological archetype in process theory posits that organizational or entity-level change occurs through purposeful, goal-directed actions aimed at achieving a envisioned end state. Entities, whether individuals, groups, or organizations, engage in adaptive processes driven by intentionality, where development unfolds as a progression toward equilibrium or desired outcomes. This archetype emphasizes the role of agency in constructing and pursuing goals, distinguishing it from variance theories that focus on identifying factors correlating with outcomes rather than the sequential dynamics of change.^[1] At its core, the teleological mechanism involves iterative cycles: entities first envision and formulate specific goals based on perceived needs or opportunities; they then commit resources and take deliberate actions to implement these objectives; progress is evaluated through feedback mechanisms, leading to adjustments or reformulation of goals if discrepancies arise. This process creates adaptive tension, propelling the entity toward its intended end while allowing for creativity and multiple pathways (equifinality) to the goal, constrained only by environmental factors and available resources.^[1] Key elements include strong individual or collective agency, where actors exercise foresight and rationality to select strategies; feedback loops that monitor performance against goals, enabling learning and refinement; and an assumption of bounded rationality, wherein decisions balance aspiration with practical limitations.^[1] Theoretical foundations of the teleological archetype are articulated in Van de Ven and Poole's framework of process motors, where teleology serves as a building block for explaining intentional development in organizations, such as through strategic planning processes that align actions with long-term visions.^[1] It finds practical application in goal-setting theory, developed by Locke and Latham, which demonstrates how specific, challenging goals direct attention, mobilize effort, and foster persistence, with feedback enhancing adaptation and performance outcomes—meta-analyses show effect sizes of 0.52 to 0.82 for challenging goals versus vague directives.^[25] The strengths of this archetype lie in its ability to account for directed, harmonious change, such as in adaptive learning cycles where entities proactively shape their evolution, contrasting with undirected processes by highlighting purposeful foresight over random variation.^[1]

Dialectical Archetype

The dialectical archetype in process theory posits that organizational and social change emerges from the confrontation and resolution of opposing forces, rather than linear progression or adaptation. Central to this archetype is the thesis-antithesis-synthesis cycle, where an initial state or entity (thesis) encounters a counterforce (antithesis), leading to tension and conflict that culminates in a new, transformed state (synthesis). This mechanism, as articulated by Van de Ven and Poole, views development as an ongoing process of negation and reintegration, where the synthesis becomes the thesis for subsequent cycles, perpetuating dynamic change without a predetermined endpoint.^[2] Key elements of the dialectical archetype include social or structural oppositions, such as power struggles between interest groups or clashes between competing ideologies within an organization. These oppositions generate inherent tensions that drive transformation through negotiation and confrontation, incorporating negation—where the antithesis challenges and potentially dismantles aspects of the thesis—resulting in qualitative shifts rather than incremental adjustments. Unlike variance theories that explain outcomes through correlations, this archetype emphasizes the temporal sequence and interactive dynamics of conflicts, building on Mohr's foundational distinction between variance and process explanations of behavior.^[2] The theoretical foundations of the dialectical archetype trace to Hegelian dialectics, which describe historical and social progress as arising from contradictions resolved through higher syntheses, adapted by Van de Ven and Poole to organizational contexts. In policy domains, this aligns with Rittel and Webber's concept of wicked problems, where ill-defined issues involving conflicting stakeholder values necessitate dialectical confrontations to evolve solutions iteratively.^[2] A primary strength of the dialectical archetype lies in its ability to capture revolutionary or disruptive change, such as paradigm shifts in organizations or societies, by highlighting how conflicts produce novel outcomes that transcend original contradictions. It proves particularly useful for analyzing social movements, where oppositional dynamics lead to transformative syntheses, offering insights into non-equilibrium processes that other archetypes overlook.^[2]

Life Cycle Archetype

The life cycle archetype in process theory describes change as the predictable progression of a single entity through a series of predetermined stages, driven by an immanent developmental program. This archetype views development as a unitary sequence of events, where each stage builds upon the previous one in a prescribed order, often analogous to biological growth cycles from birth to maturity and decline. Unlike the other archetypes, it emphasizes determinism and inevitability rather than agency, conflict, or selection.^[1] At its core, the life cycle mechanism unfolds through sequential phases triggered by internal programs or external milestones, such as inception, growth, maturity, and termination. Progress is cumulative and directional, with little room for reversal or branching paths; contingencies in early stages can influence the trajectory via path-dependent effects, where historical events shape subsequent development. Key elements include the assumption of a preordained blueprint guiding the entity, minimal emphasis on external selection or intentional adaptation, and applicability to individual, organizational, or institutional lifespans.^[1] Theoretical foundations trace to biological and developmental models, adapted by Van de Ven and Poole (1995) as one of the four basic motors of organizational change. It applies to processes like product life cycles or organizational aging, where stages like innovation, elaboration, and decay follow a natural order. Path dependence is particularly relevant here, as initial conditions can lock the entity into a specific sequence, making deviations difficult.^[1]^[26] A primary strength of the life cycle archetype lies in its simplicity for modeling linear, stage-based development, providing a framework for anticipating transitions and managing maturity phases, though it may overlook contingencies and interactions emphasized in other archetypes.

Path Dependence Archetype

While not one of the original four motors in Van de Ven and Poole's (1995) framework, the path dependence archetype has emerged as an influential extension in process theory, particularly in historical and institutional analyses. It describes a mechanism of change wherein early, often contingent events accumulate to produce increasing returns or lock-ins, rendering subsequent developments highly sensitive to historical precedents rather than optimal future alternatives. This results in non-ergodic processes, where the system's trajectory becomes locked into a particular path, making reversals costly or impossible despite potential inefficiencies. A representative illustration is the enduring dominance of the QWERTY typewriter keyboard layout, adopted in the 1870s for mechanical reasons but persisting into the digital era due to network effects and learning economies, even after more efficient designs like Dvorak emerged.^[24] Central to this archetype are three key elements: contingency and criticality, self-reinforcing feedback, and the potential for punctuated equilibria. Contingency refers to the role of small, chance occurrences in early stages that, at critical junctures, diverge possible paths without deterministic inevitability.^[26] Self-reinforcing feedback mechanisms—such as positive externalities, coordination effects, or adaptive expectations—then amplify these initial events, progressively narrowing the scope of viable options through processes like escalating commitment or complementary asset accumulation.^[27] Punctuated equilibria may arise when external shocks disrupt entrenched paths, allowing brief windows for realignment before new lock-ins form, though stability typically resumes. The theoretical foundations of the path dependence archetype trace to economics, particularly W. Brian Arthur's 1989 model of competing technologies under increasing returns, which demonstrates how historical accidents can lead to inefficient equilibria via stochastic processes.^[24] Paul David's 1985 analysis of technological standards further elaborated this by showing how interrelatedness and quasi-irreversibility sustain suboptimal standards like QWERTY. In process theory, concepts from Van de Ven and Poole (1995) have been extended to incorporate path dependence, often within evolutionary or life-cycle archetypes, to explain how historical contingencies shape developmental trajectories beyond mere variation and selection.^[28] The strengths of the path dependence archetype lie in its ability to account for inertia in systems resistant to change, highlighting non-ergodic dynamics where past events irretrievably influence futures, and emphasizing the pivotal roles of timing, sequence, and serendipity in outcomes.^[24] This contrasts with more deterministic models by underscoring how seemingly minor historical contingencies can generate enduring structures, as seen in technological and institutional persistence. While akin to evolutionary retention in preserving selected traits, path dependence uniquely stresses lock-in from self-amplifying histories rather than ongoing adaptation.^[28]

Applications

In Organizational Studies

In organizational studies, process theory provides a framework for understanding how change unfolds dynamically within firms, teams, and strategies, emphasizing temporality, sequences of events, and interactions over static structures. This approach contrasts with variance theories by focusing on the "how" and "why" of processes, such as adaptation, conflict, and evolution, rather than mere correlations between variables. Key applications include analyzing organizational change processes, where the teleological archetype explains purposeful adaptations toward desired goals, such as in mergers where firms intentionally realign structures and cultures to achieve integration. For instance, during mergers, leaders engage in iterative goal-setting, implementation, and evaluation to navigate resistance and realize synergies, highlighting how teleological processes drive convergence despite disruptions. Innovation processes also benefit from process theory, particularly through the evolutionary archetype, which views innovation as arising from variation, selection, and retention mechanisms within organizations. Robert Burgelman's intraorganizational ecology model illustrates this by examining how strategic initiatives at Intel emerged through internal competition and selection, where diverse business proposals varied, were tested against organizational criteria, and the fittest retained to adapt to external markets. This evolutionary lens reveals how innovation succeeds not through top-down directives but via decentralized experimentation and survival of adaptive practices over time. Similarly, a process study by Jean-Louis Denis, Ann Langley, and Linda Cazale of strategic change in a large public hospital illustrates how leadership roles evolve amid ambiguity and internal conflicts during change initiatives, leading to cyclical progress through collaborative tactics and political realignments.^[29] Methodological tools in process-oriented organizational research emphasize capturing temporality and sequences, such as event sequencing to reconstruct timelines of actions and decisions, and process mapping to visualize flows of activities and interactions. These techniques, advocated by scholars like Langley and Van de Ven, enable researchers to trace how events interconnect in case studies, revealing patterns like cycles of action and interruption. By prioritizing longitudinal data from observations and interviews, such methods uncover the micro-dynamics of change, such as feedback loops in team adaptations or branching paths in strategy formulation. Ultimately, these applications yield insights into why organizational changes succeed or fail, attributing outcomes to temporal contingencies rather than isolated factors—for example, timely resolutions of conflicts can prevent stagnation, while misaligned selection in evolutionary processes may lead to missed innovations.^[30]^[21] In social and behavioral sciences, process theory illuminates how social interactions and behavioral changes unfold dynamically through sequences of events and relationships, rather than static structures. In sociology, social process theories emphasize learning and adaptation via interpersonal exchanges; for instance, in criminology, Edwin Sutherland's differential association theory explains criminal behavior as a learned outcome of interactions in intimate personal groups, where individuals acquire attitudes and techniques favorable to law violation through excess exposure to such definitions over those opposing it.^[31] This perspective shifts focus from innate traits to the cumulative impact of social environments on behavioral development. Similarly, normalization process theory (NPT), developed by Carl May and colleagues, examines how innovations or complex practices become embedded in social routines by analyzing the work involved in their collective sense-making, enactment, and appraisal across groups.^[32] Key exemplars further demonstrate process theory's explanatory power. Andrew Abbott's processual sociology conceptualizes social reality as a continuous flux of events and trajectories, where micro-level interactions—such as everyday conversations or decisions—aggregate into macro-structures like institutions or inequalities through temporal linkages and iterative happenings.^[33] In psychology, dual-process theories, particularly Daniel Kahneman's model, delineate decision-making as emerging from the interplay between System 1 (automatic, heuristic-driven cognition) and System 2 (deliberate, analytical reasoning), revealing how behaviors shift based on contextual cues that activate one system over the other. The dialectical archetype, briefly, informs analyses of social conflict by framing it as evolving through oppositional processes that generate novel relational forms. Methodologically, process theory in these fields relies on tools attuned to temporality and sequence, such as narrative analysis, which interprets personal stories to uncover how individuals narrate and co-construct social processes over time, and longitudinal ethnography, which immerses researchers in settings to observe evolving patterns of exchanges and adaptations.^[34] These approaches prioritize tracking relational dynamics, like repeated interactions in peer networks, to map how behaviors transform. Ultimately, process theory yields insights into behavioral evolution by highlighting how relationships and contexts iteratively shape actions, such as the gradual normalization of new norms in communities or the contextual toggling between intuitive and reflective thinking in daily choices, fostering a deeper understanding of social fluidity.^[35]

In Implementation and Policy

Process theory informs the analysis of policy implementation by examining the sequential and interactive dynamics through which innovations, technologies, and reforms are adopted, embedded, and sustained in public administration and health systems. A prominent application is Normalization Process Theory (NPT), introduced by Carl May and Tracy Finch in 2009, which models the social processes of implementing complex interventions, such as healthcare technologies, by focusing on how practitioners collectively enact and normalize new practices amid ongoing work routines.^[36] NPT identifies four core constructs—coherence, cognitive participation, collective action, and reflexive monitoring—to explain embedding mechanisms, emphasizing that normalization depends on interactive work that aligns individual and collective efforts.^[37] In health policy, NPT has guided evaluations of electronic health records and telemedicine adoption, revealing how barriers to collective action, like inadequate training, hinder sustained integration.^[32] Another key application arises in legal and constitutional policy through political process theory, as developed by John Hart Ely in his 1980 book Democracy and Distrust, which posits that judicial review should prioritize safeguarding access to democratic processes for marginalized groups rather than substantive policy outcomes. Ely's framework views policy legitimacy as contingent on fair procedural participation, influencing U.S. Supreme Court decisions on voting rights and representation by tracing how institutional processes either enable or obstruct group inclusion in policymaking.^[38] This approach has shaped analyses of policy implementation in civil rights contexts, where courts intervene to correct process failures that perpetuate exclusion, such as gerrymandering or barriers to political mobilization.^[39] Process models in policy diffusion further apply process theory to track how policies spread across jurisdictions, often incorporating path dependence—similar to the archetype outlined earlier—to explain why welfare reforms exhibit inertia once established. For instance, Paul Pierson's analysis demonstrates that early welfare state commitments in advanced economies generate increasing returns through feedback loops like voter expectations and administrative entrenchment, complicating later retrenchment efforts in countries like Sweden and the United States during fiscal crises.^[40] In public health interventions, event-sequence analysis dissects temporal patterns of events to assess rollout dynamics, such as sequencing vaccination campaigns or outbreak responses, identifying critical junctures where delays amplify risks.^[41] Methodological tools central to these applications include process tracing, which systematically examines evidence of causal chains in policy sequences to test theories of implementation mechanisms, as applied in evaluations of international development aid programs. Realist evaluation extends this by configuring contexts, mechanisms, and outcomes to explain policy effects in varied settings, particularly in health systems where it uncovers how resource allocation triggers collective action for intervention uptake. Both tools highlight embedding processes, where policies gain traction through iterative interactions, and collective action, involving stakeholder coordination to overcome resistance during adoption phases.^[42] By illuminating adoption sequences, process theory outcomes enable policymakers to anticipate and mitigate barriers, such as sequencing errors in reform timelines, thereby enhancing the scalability and longevity of public health initiatives like chronic disease management programs.^[37]

Criticisms and Limitations

Methodological Challenges

One of the primary methodological challenges in researching process theories lies in capturing temporality, which necessitates the collection of longitudinal data to observe events unfolding over time. This approach is inherently resource-intensive, demanding sustained access to participants, repeated data gathering across multiple sites, and significant time commitments from researchers, often spanning years in organizational or social contexts. For instance, in studies of business networks, longitudinal field research requires integrating diverse data sources like interviews, observations, and archival records, which can strain logistical and financial resources while risking participant fatigue or dropout.^[43] Sequencing events in process research introduces risks of post-hoc bias, where retrospective accounts may impose a false linear order on complex, non-chronological dynamics, leading to hindsight distortions in interpreting causal links. Participants' narratives often evolve or contradict over time, complicating efforts to reconstruct accurate timelines without researcher-imposed interpretations that overlook contextual nuances. This bias is particularly acute in qualitative process-oriented studies, where shifting participant perspectives amplify interpretive challenges during data synthesis.^[44] Equifinality, the principle that multiple pathways can lead to the same outcome, further complicates establishing causality in process theories, as it undermines traditional linear models by highlighting path diversity and contextual contingencies. In organizational settings, this multiplicity makes it difficult to isolate definitive causal mechanisms, requiring researchers to account for alternative routes without overgeneralizing from singular cases. Such complexity challenges the attribution of outcomes to specific processes, often resulting in ambiguous empirical validations.^[45] Integrating qualitative narratives—such as rich, contextual descriptions of unfolding events—with quantitative measures, like event frequency or duration metrics, presents additional hurdles, including data incompatibility and the need for rigorous triangulation to ensure coherence. Mixed-methods approaches in process research demand careful alignment of interpretive depth with statistical rigor, yet inconsistencies between narrative fluidity and numerical precision can obscure holistic insights. Challenges arise in synthesizing these elements without privileging one over the other, potentially diluting the dynamic essence of processes.^[46] To address these issues, researchers have developed solutions like process-tracing methods, which systematically map causal mechanisms through detailed evidence chains to mitigate biases in sequencing and temporality. Pioneered in social science applications, these techniques differentiate between theoretical testing, building, and exploration variants, enabling robust validation of process dynamics. Complementing this, software tools for temporal mapping, such as TimelineJS, facilitate visualization of event sequences and interconnections, aiding in the management of longitudinal datasets by allowing interactive reconstruction of timelines from qualitative and quantitative inputs.^[47]^[48] These methodological constraints limit the generalizability of process theory findings compared to variance models, which rely on cross-sectional correlations for broader predictive applicability. Process research's emphasis on idiographic, context-specific narratives often yields transferable insights rather than universal laws, restricting scalability across diverse settings and prioritizing depth over breadth in theoretical contributions.^[21]

Theoretical Debates

One major theoretical debate within process theory centers on its potential overemphasis on linear sequences of events, which critics argue fails to adequately capture the non-linear dynamics inherent in complex social systems. Drawing from complexity theory, scholars contend that process accounts often assume predictable trajectories of change, overlooking emergent patterns, feedback loops, and sensitivity to initial conditions that characterize chaotic or non-linear processes in organizations and societies.^[49] For instance, while process theory excels at tracing causal chains through time, it may undervalue how small perturbations can lead to disproportionate outcomes, as highlighted in critiques inspired by chaos theory applications to organizational behavior.^[50] This tension prompts calls for process models to incorporate greater ontological flexibility to address the "tangled world" of interdependent, evolving entities.^[51] A related controversy involves the balance between agency and structure in conceptualizing social processes. Process theory posits that social phenomena unfold through ongoing interactions where actors both draw upon and reshape structural constraints, echoing Anthony Giddens' structuration framework, which emphasizes the duality of structure as both medium and outcome of human action. However, debates persist over whether process approaches sufficiently theorize the recursive interplay, with some arguing that they tilt toward agential narratives at the expense of enduring structural forces, potentially underplaying power asymmetries or institutional inertia in social dynamics.^[52] This agency-structure dialectic remains a flashpoint, as unresolved imbalances can limit process theory's explanatory power for phenomena like collective mobilization or institutional reproduction. Process theory also faces limitations in its reliance on narrative sequences, which pose challenges to falsifiability and empirical rigor. Unlike variance theories that test causal variables through hypothesis-driven models, process narratives often describe how events unfold without clear criteria for disconfirmation, raising concerns about post-hoc rationalization and subjective interpretation. Furthermore, by prioritizing temporal flows, process theory risks reductionism by marginalizing stable variances—such as contextual invariants or equilibrium states—that variance paradigms highlight, potentially leading to incomplete accounts of persistence amid change.^[53] These issues echo Lawrence Mohr's foundational distinction between process and variance explanations, underscoring the need for complementary methods to enhance testability. In comparison to other paradigms, process theory shares affinities with but diverges from critical realism, which emphasizes generative mechanisms underlying observable events with deeper ontological commitments to stratified reality. While both attend to processes as causal engines, critical realism critiques process theory for insufficiently addressing underlying structures and transitive knowledge production, advocating for a more robust realism to explain emergence beyond surface narratives.^[54] Similarly, actor-network theory (ANT) overlaps with process theory in its relational, becoming-oriented view of socio-material assemblies but extends it by symmetrically including non-human actants, critiquing process accounts for anthropocentric biases and limited emphasis on network stabilization.^[55] ANT thus highlights process theory's relative underdevelopment in tracing heterogeneous associations, though both paradigms advance anti-essentialist understandings of change. Looking ahead, theoretical advancements in process theory increasingly favor hybrid models that integrate processual dynamics with variance elements to overcome these debates and limitations. Such syntheses, as explored in information systems and organizational research, blend event sequences with variable correlations to model both temporal unfolding and configurational stability, enabling more comprehensive explanations of complex phenomena.^[56] This trajectory promises to enrich process theory's scope, fostering interdisciplinary dialogues that address non-linearity, agency-structure tensions, and empirical robustness while preserving its core focus on becoming over being.
