Tacit Knowledge
    The implicit knowledge used by organizational members to perform their work and to make sense of their worlds.

    Tacit knowledge is hard to verbalize because it is expressed through action-based skills and cannot be reduced to rules and recipes.

Explicit Knowledge
    Knowledge that can be expressed formally using a system of symbols, and can therefore be easily communicated or diffused.

    Explicit knowledge may be object-based or rule-based.

Cultural Knowledge
    The cognitive and affective structures that are habitually used to perceive, explain, evaluate, and construct reality.

    The assumptions and beliefs that are used to describe and explain reality, as well as the conventions and expectations that are used to assign value and significance to new information.
