Explicit knowledge (also expressive knowledge)[1] is knowledge that can be readily articulated, conceptualized, codified, formalized, stored and accessed.[2] It can be expressed in formal and systematical language and shared in the form of data, scientific formulae, specifications, manuals and such like.[3] It is easily codifiable and thus transmittable without loss of integrity once the syntactical rules required for deciphering it are known.[4] Most forms of explicit knowledge can be stored in certain media. Explicit knowledge is often seen as complementary to tacit knowledge.[5]

Explicit knowledge is often seen as easier to formalize compared to tacit knowledge, but both are necessary for knowledge creation. Nonaka and Takeuchi introduce the SECI model as a way for knowledge creation. The SECI model involves four stages where explicit and tacit knowledge interact with each other in a spiral manner. The four stages are:

  • Socialization, from tacit to tacit knowledge
  • Externalization, from tacit to explicit knowledge
  • Combination, from explicit to explicit knowledge
  • Internalization, from explicit to tacit knowledge.[5]

Examples

[edit]

The information contained in encyclopedias and textbooks are good examples of explicit knowledge, specifically declarative knowledge. The most common forms of explicit knowledge are manuals, documents, procedures, and how-to videos. Knowledge also can be audio-visual. Engineering works and product design can be seen as other forms of explicit knowledge where human skills, motives and knowledge are externalized.

In the scholarly literature, papers presenting an up-to-date "systemization of knowledge" (SoK) on a particular area of research are valuable resources for PhD students.[6]

Explicit knowledge

View on Grokipedia
from Grokipedia
Explicit knowledge refers to information that is codified, articulated, and readily transmittable in formal, systematic language, such as words, numbers, formulas, or diagrams, making it easily shareable without requiring personal interaction. This type of knowledge is objective and rational, often context-free, and can be stored in tangible forms like documents, databases, manuals, patents, or electronic media, facilitating its reuse across individuals or organizations. Originating from foundational work in knowledge management, explicit knowledge contrasts sharply with tacit knowledge, which is intuitive, personal, and difficult to verbalize, as it emphasizes structured expression over experiential insight. In organizational contexts, explicit knowledge plays a central role in processes like knowledge creation and , particularly through models such as Nonaka and Takeuchi's SECI framework, where it is combined from existing explicit sources (e.g., via meetings, emails, or databases) to generate new insights and internalized by individuals to become actionable tacit understanding. It supports routine problem-solving, of practices, and efficiency in predictable environments, such as through guidelines, policies, or technical specifications that ensure uniform application without ambiguity. For instance, in settings, explicit knowledge enables the extraction and storage of best practices in knowledge repositories, allowing for scalable sharing via systems like hierarchical databases or libraries. The management of explicit knowledge is essential for competitive advantage, as it allows organizations to document and leverage intellectual assets systematically, though it requires significant investment in codification and technology to avoid loss during transitions like employee turnover. Key characteristics include its verifiability through formal education or structured training, and its suitability for evaluation based on tangible outcomes rather than subjective creativity. While explicit knowledge excels in stability and reuse, its limitations in dynamic or innovative scenarios highlight the need for integration with tacit elements to foster holistic knowledge creation.

Definition and Characteristics

Definition

Explicit knowledge refers to information that is articulated, documented, and systematically organized, allowing it to be easily expressed, shared, and transferred through formal mechanisms such as writing, diagrams, databases, or . This form of knowledge is objective and rational, capable of being conveyed in words, sentences, numbers, or formulas without dependency on context or personal interpretation. In , it encompasses theoretical and practical content that can be codified into reusable formats, facilitating efficient dissemination across individuals or organizations. Key attributes of explicit knowledge include its codified nature, which enables storage and retrieval independent of the original holder; its detachment from individual subjectivity, allowing multiple users to access it uniformly; and its , ensuring that the retains its meaning and utility when duplicated or shared. Unlike intuitive or experiential insights, explicit knowledge does not diminish in value through transmission, as it relies on structured representation rather than personal embodiment. The term "explicit knowledge" originates from the tacit-explicit dichotomy introduced by philosopher in his 1958 work Personal Knowledge, where he contrasted articulable, formal knowledge with unspoken, subsidiary awareness. This distinction was later refined in literature, particularly by and in the , who emphasized explicit knowledge's role in organizational learning processes like knowledge conversion. Within broader epistemological categories, explicit knowledge aligns closely with , which involves factual, "know-what" propositions that can be stated and verified, such as definitions or principles, in contrast to focused on "know-how" skills. This positioning highlights explicit knowledge's emphasis on describable content over performative actions, though codified procedures can sometimes bridge the two. As the counterpart to , which remains intuitive and hard to verbalize, explicit knowledge forms the foundation for formalized systems in various domains.

Key Characteristics

Explicit knowledge is distinguished by its articulability, allowing it to be clearly expressed and documented in formal, systematic without significant , such as through words, numbers, symbols, or structured representations. This property enables precise verbalization or codification, making it accessible for communication and analysis in a straightforward manner. A core feature of explicit knowledge is its transferability, which facilitates easy dissemination among individuals or groups via established mechanisms like databases, manuals, reports, and digital platforms, thereby supporting efficient sharing without reliance on personal interaction. Explicit knowledge lends itself to storability, permitting long-term preservation in various media including books, electronic databases, software repositories, and archival systems, which ensures its endurance and repeated retrieval over extended periods. represents another key trait, as explicit knowledge adopts uniform formats and protocols that promote , consistency, and across diverse users and contexts, often embodying universal principles or procedural norms. Representative examples of explicit knowledge formats include textual documents such as technical reports, mathematical formulas like E=mc2E = mc^2 that codify fundamental physical laws, and procedural algorithms, for instance, the steps in a binary search routine, which can be precisely documented and replicated.

Historical Development

Origins in and

The concept of explicit knowledge, as a form of articulated and codifiable information, traces its philosophical roots to thought, particularly 's distinctions among types of knowledge in works such as the and . differentiated —scientific or theoretical knowledge that is demonstrable, universal, and expressible through rational principles—from , which involves practical skills and craftsmanship acquired through experience and application. This binary laid early groundwork for viewing knowledge as either systematically explainable (, akin to explicit) or intuitively applied (, more akin to tacit). In the , the modern tacit-explicit divide emerged prominently through Michael Polanyi's seminal work Personal Knowledge: Towards a Post-Critical (1958), where he argued that much human knowing is personal and subsidiary, with explicit knowledge representing only the focal, articulable portion of a broader cognitive process. Polanyi posited that explicit formulations rely on an underlying tacit integration. He later synthesized these ideas in The Tacit Dimension (1966), famously stating that "we can know more than we can tell," thereby establishing explicit knowledge as the codified, communicable counterpart to ineffable tacit dimensions. Early applications in arose in industrial contexts, where explicit knowledge was operationalized through documentation to enhance efficiency. Frederick Winslow Taylor's principles of , outlined in (1911), emphasized breaking down tasks into measurable components, standardizing procedures, and recording them in manuals to eliminate variability and train workers uniformly—effectively codifying practical knowledge for scalable replication. During , this approach intensified in and defense sectors, as organizations involved in the U.S. (TWI) program developed job instruction sheets and process charts to rapidly document and disseminate expertise amid wartime labor shortages and technological shifts, prioritizing explicit records for consistent production and training. A key milestone came in 1966 with Polanyi's The Tacit Dimension, which synthesized his earlier ideas into a framework that highlighted the interplay between tacit and explicit elements, profoundly shaping subsequent by underscoring the limits of pure codification in professional and institutional settings.

Evolution in Knowledge Management Theory

In the 1990s, the concept of explicit knowledge gained prominence in theory through and Hirotaka Takeuchi's SECI model, which outlines a spiral process of knowledge creation involving , externalization, , and internalization. In this framework, explicit knowledge emerges as a key outcome of externalization, where tacit insights are articulated into codified forms such as documents or diagrams, enabling broader organizational sharing and with existing explicit resources. Corporate adoption of explicit knowledge management accelerated in the mid-1990s, driven by advancements in that facilitated the creation of centralized repositories for storing and retrieving codified knowledge. For instance, launched its initial knowledge management initiatives in 1994, focusing on through business units that developed repositories to capture explicit knowledge like best practices and technical documentation, supporting reuse across global operations. This shift marked explicit knowledge as a strategic asset, aligning with the era's emphasis on leveraging IT for efficiency in large-scale enterprises. Academic contributions further solidified explicit knowledge's role in the late , as seen in Davenport and Prusak's analysis of knowledge as an organizational asset that drives when systematically managed. They highlighted how explicit knowledge, in forms like and reports, could be inventoried and deployed to enhance and , distinguishing it from less structured tacit elements. By the 2000s, knowledge management theory refined its approach to explicit knowledge through deeper integration with digital tools, particularly the , which enabled scalable codification and dissemination via systems (KMS). These systems supported the storage, search, and application of explicit knowledge, transforming static repositories into dynamic platforms that facilitated real-time access and across distributed teams.

Relationship to Tacit Knowledge

Conceptual Distinctions

Explicit knowledge is characterized as formal, systematic, and objective, readily expressed in words, numbers, or symbols, and easily documented for sharing, in contrast to , which is subjective, experiential, and deeply embedded in personal context, making it inherently personal and less amenable to straightforward articulation. This distinction underscores explicit knowledge's role as a structured, verifiable entity independent of individual perspectives, while relies on , emotions, and situational nuances that vary across individuals. Key dimensions of contrast include ease of communication and methods of acquisition. Explicit knowledge facilitates high transferability through codified forms like documents or databases, enabling broad dissemination without loss of meaning, whereas poses low communicability due to its unarticulated nature, often requiring social interaction for partial conveyance. In terms of acquisition, explicit knowledge is typically gained through formal channels such as reading texts, attending lectures, or consulting records, promoting efficient, replicable learning; , however, is acquired via , , and hands-on practice, where skills are internalized through repeated engagement in context. This divide is vividly illustrated by , which states that "we can know more than we can tell," highlighting the inherent gap where much human understanding remains and resists full explication, even as explicit representations build upon underlying foundations. Rather than a strict binary, explicit and are often viewed as endpoints on a continuum, with most forms of exhibiting varying degrees of both, allowing for dynamic interplay in real-world applications.

Integration Models

One prominent framework for integrating explicit and tacit knowledge is the SECI model, developed by and , which outlines a cyclical process of knowledge creation through four conversion modes. Socialization involves the sharing of tacit knowledge between individuals, such as through observation, imitation, and practice in joint activities, allowing experiential insights to transfer without formal articulation. Externalization converts tacit knowledge into explicit forms, often via metaphors, analogies, or models that articulate personal experiences into concepts, documents, or prototypes. Combination integrates different explicit knowledge sources, such as combining documents, data, or formulas to form more complex systems or innovations. Internalization occurs when explicit knowledge is absorbed and transformed back into tacit knowledge through practice, experimentation, or reflection, embedding it into individuals' skills and mental models. The SECI model conceptualizes these conversions as a "spiral" of creation, where interactions between tacit and explicit expand from to group, organizational, and inter-organizational levels, fostering continuous amplification and . This spiral enhances organizational by enabling the dynamic synthesis of diverse forms, leading to new products, processes, and competitive advantages. Another influential model is Frank Blackler's typology of organizational knowledge (1995), which categorizes knowledge into five interconnected types to illustrate how explicit and tacit elements are embedded in organizational contexts. Encoded knowledge represents the explicit dimension, manifested in formalized symbols, rules, and media such as , manuals, and procedures that can be easily communicated and stored. In contrast, the other types—embrained (cognitive and conceptual), embodied (practical and skill-based), encultured (shared understandings), and embedded (systemic routines)—align more closely with , highlighting its situated and relational nature. Blackler's framework emphasizes integration by viewing as an active, mediated process where these types interact within cultural and organizational systems to generate new knowing and adapt to change. Practical integration of explicit and tacit knowledge often occurs through communities of practice, informal groups of individuals who share a common domain and engage in collective learning to advance their expertise. These communities facilitate the conversion of tacit knowledge to explicit forms by encouraging interactions such as storytelling, joint problem-solving, and documentation efforts, which articulate unspoken insights into reusable artifacts like guides or best practices. As Etienne Wenger describes, such groups address both the tacit, dynamic aspects of knowledge sharing—through direct engagement—and the explicit aspects, by building a shared repertoire of resources that links individual learning to organizational performance.

Examples and Applications

In Organizational Contexts

In organizational contexts, explicit knowledge serves as a foundational asset for businesses and institutions, manifested in structured, documented forms that facilitate and . Company manuals, such as standard operating procedures (SOPs) and employee handbooks, exemplify explicit knowledge by codifying routine processes and guidelines that can be readily accessed and applied across teams. Patents represent another critical repository, where innovations and technical specifications are formally documented to protect and enable licensing or replication within the firm. Similarly, (CRM) databases aggregate explicit knowledge through structured records of client interactions, sales data, and preferences, allowing organizations to analyze patterns and tailor strategies systematically. A notable case study illustrating the codification of explicit knowledge is 's response to the 1986 Challenger disaster, which exposed vulnerabilities in communication and procedural adherence. In the aftermath, implemented enhanced practices, including the establishment of the Lessons Learned Information System (LLIS) in 1994, a centralized repository designed to capture and store explicit from past incidents. This system required program managers to review codified lessons and procedures, transforming experiential insights into documented protocols to mitigate risks and prevent recurrence of errors in future missions. The initiative marked a shift toward codification strategies, balancing tacit with explicit documentation to bolster organizational resilience. Organizations employ various digital tools to manage and retrieve explicit knowledge effectively. Wikis function as collaborative platforms for creating and editing documented content, enabling teams to build and maintain repositories of procedures and best practices in a structured, version-controlled manner. Intranets serve as internal portals that centralize explicit knowledge, hosting searchable of policies, reports, and guidelines to support quick access and reduce redundancy. (ERP) systems integrate explicit knowledge across business functions, such as and finance modules, by embedding standardized data and workflows that ensure consistent application and . To quantify the value of explicit knowledge, organizations conduct knowledge audits, systematic assessments that identify, evaluate, and appraise knowledge assets for inclusion in financial reporting. These audits measure the economic contribution of explicit repositories, such as and manuals, by estimating their impact on productivity and innovation, often valuing them as intangible assets on balance sheets under frameworks like accounting. For instance, audits may assign monetary values based on reuse potential and cost savings, helping firms reflect these assets' role in overall valuation, as seen in resource-based evaluations that integrate knowledge metrics with traditional .

In Educational and Technological Settings

In educational settings, explicit knowledge serves as the foundation for structured learning by providing codified, accessible information that can be systematically transmitted to learners. Textbooks exemplify this, as they articulate concepts, facts, and procedures in a formal, written format that facilitates uniform understanding and replication across diverse student populations. Standardized curricula further embody explicit knowledge through predefined learning objectives, syllabi, and assessment frameworks that ensure consistent educational delivery, enabling educators to align teaching with measurable outcomes. Massive Open Online Courses (MOOCs) represent a digital extension of explicit knowledge transmission, delivering structured content such as video lectures, reading materials, and interactive modules that learners can access and internalize at their own pace. In MOOCs, this is often derived from recorded lectures, forum discussions, and instructional guides, which codify insights for broad dissemination and support the conversion of explicit content into personal understanding through . These platforms parallel organizational databases in their role as repositories for retrievable, shareable information, though they prioritize pedagogical over operational efficiency. In technological contexts, explicit knowledge manifests in tools that enable precise, reproducible interactions and innovations. Application Programming Interfaces (APIs) codify software functionalities through detailed specifications and protocols, allowing developers to integrate systems without reinventing underlying logic. Open-source code documentation similarly captures explicit knowledge by documenting algorithms, functions, and usage guidelines in repositories like , fostering collaborative development and reuse among global contributors. AI training datasets exemplify codified explicit knowledge, consisting of labeled, structured data that models process to identify patterns and generate predictions. Wikipedia stands as a prominent of explicit knowledge as a global, collaborative resource, where volunteers articulate and refine factual content through editable articles that formalize information for public access. This platform's structure supports the externalization of , transforming individual contributions into a verifiable, interconnected base that anyone can consult or expand. The integration of explicit knowledge in AI underscores its transformative impact, as models depend on high-quality datasets to train on discernible patterns, enabling applications from image recognition to without requiring hardcoded rules.

Implications and Challenges

Benefits for Knowledge Transfer

Explicit knowledge facilitates in knowledge by allowing codified information, such as documents and databases, to be disseminated to large audiences without requiring direct personal interaction from the original knower, thereby reducing the time and effort needed for training and . This approach enables organizations to efficiently scale operations, as seen in cases where reusable solutions from explicit repositories cut development times significantly. The preservation of explicit knowledge extends its longevity beyond individual lifespans or tenures, as it can be archived in stable digital or physical systems that maintain over time. This ensures that critical information remains available for future use, supporting continuity in knowledge-intensive fields where personnel turnover is high. is enhanced through the of explicit knowledge, which democratizes its distribution via platforms like journals and online repositories, allowing global users to retrieve and apply it without barriers. In organizational contexts, this often manifests as shared digital libraries that promote equitable access among employees. Economically, explicit knowledge yields quantifiable returns on investment in sectors like consulting, where codification strategies correlate with improved and by minimizing redundancy in knowledge reuse. Firms emphasizing explicit report higher firm valuation through streamlined and competitive advantages derived from readily deployable insights.

Limitations and Criticisms

One major limitation of explicit knowledge lies in the loss of contextual nuances during its codification , which can result in misapplication when users rigidly adhere to decontextualized guidelines, such as outdated operational manuals that fail to account for evolving situational factors. This stripping of context occurs because codification often proceeds without consideration of the end-use environment or intended audience, making the knowledge difficult to interpret and apply effectively in practice. Criticisms of explicit knowledge, particularly from post-1990s , emphasize its inseparability from tacit elements, challenging the notion that knowledge can be fully articulated and detached from personal knowing. In their seminal work, Cook and Brown argue that explicit knowledge interacts dynamically with tacit knowing in a "generative ," where neither can exist independently, rendering attempts to isolate explicit forms incomplete and potentially misleading for organizational practices. This perspective highlights how over-reliance on explicit codification overlooks the interpretive role of tacit skills in decoding and applying such knowledge, leading to flawed strategies that undervalue embodied expertise. An overemphasis on explicit knowledge accumulation exacerbates risks of digital overload, where vast repositories of codified information become unmanageable "information junkyards," hindering retrieval and contributing to knowledge hoarding behaviors as employees struggle with excessive, unfiltered content. For instance, large-scale codification efforts in consulting firms have resulted in millions of documents overwhelming users, reducing the overall utility of explicit knowledge systems despite their intent to facilitate sharing. Maintenance poses another critical challenge for explicit knowledge in dynamic fields, as codified artifacts like rapidly become obsolete without ongoing updates, leading to inefficiencies and knowledge gaps in fast-evolving environments. In , for example, legacy systems often lack synchronized , forcing practitioners to expend 40-60% of their effort reconstructing understanding from code rather than relying on reliable explicit records, underscoring the need for continuous revision to preserve relevance.
