Managing Knowledge

The SECI Model by Nonaka & Takeuchi

The SECI Model of Knowledge, illustrates the transition from “Implicit” to “Explicit Knowledge”. It addresses the challenge of generating and sharing knowledge at both the individual and organisational level by enabling a continuous transformation process between Implicit and Explicit Knowledge. It was developed in the 1990s by Japanese organisational theorists Ikujiro Nonaka and Hirotaka Takeuchi.

The SECI Model is a core element of knowledge management because it facilitates knowledge creation and knowledge sharing within organisations. It helps organisations use their knowledge effectively to foster innovation, improve decision-making, and gain a competitive advantage.

What Defines the SECI Model?

The model is based on two types of knowledge: Implicit and Explicit. Implicit Knowledge refers to the knowledge stored in one’s mind, difficult to articulate or document. It is rooted in experience, intuition and skills, making it highly contextual. Explicit Knowledge can be articulated, documented and systematically shared with others. 

The Four Phases of Knowledge Conversion

Seci Model

The aim of the SECI Model according to Nonaka and Takeuchi is to transform implicit knowledge into explicit knowledge. This takes place in four phases that progress in the form of a spiral. These four phases are as follows:

 

1. Socialization

    • Acquiring Implicit Knowledge through shared experience
    • Learning through observation, imitation and practice
    • Examples: observation, apprenticeships, mentoring relationships

2. Externalization

    • Transforming Implicit Knowledge into Explicit Knowledge
    • Articulating personal insights through dialogue or documentation
    • Examples: metaphors, analogies, models, hypotheses

3. Combination

    • Integrating different sources of Explicit Knowledge
    • Learners combine information, create connections and build new complexity
    • Examples: Using documents, meetings, networks or IT systems to synthesise knowledge

4. Internalisation

    • Converting Explicit Knowledge back into Implicit Knowledge
    • Applying newly learned knowledge until it becomes routine
    • Examples: “Learning by doing”

Advantages and Challenges

Like any method, the SECI Model brings both benefits and potential obstacles when applied in practice.

Advantages

Improved collaboration: The SECI model encourages employees to share their knowledge with others. Both the sharing process and the conversion of tacit into explicit knowledge require cooperation, across teams and departments. This strengthens collaboration not only in knowledge management, but across the organisation.

Innovation: Knowledge transformation fosters innovation. When employees exchange experiences and perspectives, new ideas emerge, sometimes around knowledge management itself, sometimes in entirely different areas of the organisation.

Enhanced organisational learning: Many organisations do not yet operate within a knowledge-friendly culture. The model simplifies the path toward establishing one, as it provides a clear process for turning individual knowledge into a shared organisational resource.

Challenges

Resistance to change: Knowledge management, including the SECI Model, often brings significant change. Employees may fear that sharing their knowledge reduces their personal value or that their expertise could be “taken away”.

Difficulty measuring ROI: Even though knowledge clearly creates value, its financial impact is difficult to express quantitatively. This makes it challenging for ROI-driven organisations to assess the direct return of knowledge management initiatives.

Need for a supportive organisational culture: The SECI Model requires a culture that supports sharing, learning and dialogue. Not all organisations have such a culture in place, and building one requires time, effort and leadership commitment.

Conclusion

Successfully transforming Knowledge with the SECI Model

The SECI Model offers a valuable framework for understanding and enabling knowledge creation. It plays a crucial role in modern knowledge management. Looking ahead, future developments may involve integrating technologies such as AI or machine learning into themodel, further enhancing the process of generating and transforming knowledge.
