Seci ModelEdit
The SECI model (often written as SECI model in scholarly literature, though some sources use the form Seci) is a framework for understanding how knowledge is created, transformed, and mobilized within organizations. Developed in the 1990s by Ikujiro Nonaka and Hirotaka Takeuchi, it posits that knowledge moves through a spiral of conversion between tacit knowledge, which is personal, context-specific, and hard to articulate, and explicit knowledge, which is codified and easily communicated. The model has become a cornerstone in discussions of organizational learning, innovation, and competitive advantage in knowledge-driven economies. It rests on the idea that effective management of internal knowledge flows can raise productivity, accelerate product development, and improve service delivery.
The SECI model highlights the central role of social interaction and practice in turning individual know-how into organizational assets. By coordinating how people share experiences, articulate insights, codify procedures, and rehearse new capabilities, a firm can build a shared repository of know-how that supports scalable outcomes. In discussions of business strategy and management, the model is frequently linked with the broader field of knowledge management and with theories of the learning organization. It is also connected to the ideas of continuous improvement and operational excellence that many firms pursue in competitive markets. Throughout, the four modes of knowledge conversion—socialization, externalization, combination, and internalization—anchor the model and provide a vocabulary for analyzing how learning occurs in teams and across organizational boundaries.
Origins and Core Concepts
The SECI model originates from the work of Nonaka and Takeuchi on how organizations create new knowledge. It draws a distinction between tacit knowledge, which is rooted in personal experience and often difficult to articulate, and explicit knowledge, which can be codified into documents, specifications, and formal procedures. The model argues that knowledge creation emerges from dynamic interaction among individuals and groups as they move through the four modes of conversion:
- socialization: tacit knowledge is shared through shared experiences, observations, and imitation, without explicit articulation
- externalization: tacit knowledge is expressed as explicit concepts, models, metaphors, and design blueprints
- combination: explicit knowledge is integrated and reconfigured through systems, databases, and cross-functional collaboration
- internalization: explicit knowledge is tested and absorbed, becoming tacit again as individuals apply it in practice
These transitions are not strictly linear; they form a spiral of learning where knowledge is continually reinterpreted and re-codified as practices evolve. The model emphasizes the social character of knowledge creation, including the importance of interactions, communities of practice, and organizational routines. The SECI cycle has been integrated with broader theories of organizational learning and has influenced how many firms think about training, onboarding, product development, and knowledge-sharing incentives.

Mechanisms and Dynamics
In practice, the SECI model guides how teams capture experiential learning and translate it into scalable capabilities. Tacit knowledge—such as hands-on expertise, intuitive judgment, and context-specific know-how—becomes explicit when individuals articulate it, codify it in manuals, diagrams, or models, and share it across the organization (externalization). Conversely, explicit knowledge—like documented procedures or engineering specifications—can be internalized by others as they apply it to real-world tasks, thus becoming tacit again through practice and refinement (internalization). The socialization phase relies on direct interaction and shared activities, allowing nascent know-how to circulate informally within teams. Combination involves integrating diverse explicit sources into broader systems or repositories, while internalization closes the loop by turning codified knowledge back into skilled performance.
The model has been influential in explaining how firms scale specialized capabilities, standardize processes, and transfer know-how across departments or sites. It emphasizes the role of organizational structures—communities of practice, training programs, documentation standards, and collaborative tools—in shaping how knowledge moves. Citations to the four modes often appear in discussions of knowledge management strategies, process improvement, and innovation programs.

Adoption, Applications, and Implications
Companies large and small have applied the SECI model to reform training, onboarding, and knowledge transfer in areas such as manufacturing, information technology, healthcare, and public services. In manufacturing, codifying best practices through standard operating procedures and playbooks aligns with the combination and externalization steps, enabling faster replication of high-quality results. In technology and software development, rapid prototyping and post-mortem analyses mirror externalization and internalization as teams convert hands-on experience into reusable design patterns and tacit competencies. In service industries, mentorship, shadowing, and cross-functional collaboration support socialization, helping staff acquire tacit know-how that improves customer-facing performance.
The model also intersects with other managerial ideas that seek to accelerate value creation. It complements approaches to open innovation, where external sources of knowledge are brought in and codified (combination) before being translated into new capabilities (internalization). It underpins discussions about digital transformation, where organizations seek to preserve core know-how while expanding new digital competencies.

Controversies and Debates
Like any influential theory of organizational learning, the SECI model has sparked debates about its scope, accuracy, and practical limits. Critics have pointed out that:
- The depiction of knowledge flow as a four-mode cycle can oversimplify how learning occurs in real organizations, where knowledge moves in non-linear, asynchronous patterns and is influenced by power, culture, and informal networks. Some scholars argue that tacit knowledge resists codification in meaningful ways, and that not all tacit elements are readily externalized.
- The emphasis on codification and transfer within hierarchies can risk promoting excessive documentation or “knowledge hoarding” if incentives and governance are misaligned. In fast-moving fields, overly rigid codification may hinder experimentation and agility.
- The model presumes a relatively stable organizational context. In highly dynamic environments, cross-boundary collaboration, external partnerships, and open networks may play a larger role than internal knowledge conversion alone.
- Critics from various perspectives have suggested that knowledge management in practice must pay careful attention to governance, culture, and ethics; without these, knowledge systems can become bureaucratic or instrumental rather than genuinely innovative.
From a practical standpoint, supporters of the SECI model argue that when implemented with clear value objectives, governance, and alignment to business results, the model helps reduce duplication, accelerates training, and creates a repeatable path from experience to capability. Proponents also note that codification enables accountability, measurable learning outcomes, and better risk management through standardized procedures. In debates about innovation and organizational design, the SECI framework is often defended as a pragmatic scaffold that can be integrated with agile methods, cross-functional teams, and performance metrics.
Wider criticisms sometimes labeled as ideological in nature contend that knowledge management tools can be used to impose a uniform corporate culture or to monitor workers’ learning activities. Proponents respond that the SECI model is a neutral mechanism for converting practical experience into shareable assets, and that the real driver of any organizational culture is leadership, incentives, and the broader policy environment. In this light, the model is viewed as a toolkit for leaner operations, better alignment between knowledge assets and business goals, and clearer paths from training to performance.
