**13. Components of knowledge management system**

Knowledge management *Use Cases* and interfaces. The major knowledge management *Use Cases* and interfaces at the Enterprise knowledge management (K) domain are depicted at the *Use Case diagram* (UML) in Fig. 31. There are four types of *Actors* associated with particular level of the enterprise Knowledge management (K) domain: a top manager (a chief executive), a Knowledge base administrator, an enterprise management expert, and a business process manager (Gudas, Brundzaite, 2007).

The enterprise knowledge self-organization activity is a responsibility of a chief executive. It includes interfaces with use cases Strategic knowledge management functions (F1) and Knowledge base management functions (F2).

Responsibilities of a knowledge base administrator includes interfaces for administration of use cases Strategic knowledge management functions (F1), Knowledge base management functions (F2), "enterprise knowledge management functions (F3), and BP knowledge management functions (F4).

The responsibilities of an enterprise management expert are focused on the development of a definite new knowledge and requirements for improvement of BP management functions (using interfaces with use cases Enterprise knowledge management functions (F3), BP knowledge management functions (F4), and Knowledge base management functions (F2)).

The BP managers access definite knowledge aimed to perform BP management and BP management control (using interfaces with the use case BP management functions (F)), and use interface with BP knowledge management functions (F4) to access definite knowledge for modification of BP management functions.

The major Classes of Enterprise Knowledge base. Enterprise knowledge modelling method could be used for construction of the integrated enterprise knowledge base, which is considered as the basic component of the knowledge-based enterprise. Enterprise knowledge base will enable transformation of the enterprise into knowledge-based business as well as to solve business and IT alignment and enterprise IT management problems.

The major classes of the enterprise knowledge base are derived from formal description of Enterprise Knowledge Space and are defined as Enterprise Knowledge Model *M*.

Knowledge-Based Enterprise Framework: A Management Control View 213

The Enterprise Knowledge Model *M* is composed of interrelated items *m* and enables modelling a knowledge-based business, as it considers enterprise modelling knowledge (identifier *k*), business processes (identifier *b*), IT (identifier *t*), and their interactions. Each aspect (*b, t, k*) is modelled into the 5 levels of detail in the Enterprise Knowledge Space

In Fig. 28, the Enterprise knowledge structure (subsets of knowledge) is presented by class

Consequently, Enterprise Knowledge Base contains integrated knowledge about three enterprise domains: business (*B*), information technology (*T*) and knowledge (*K*), as well as

The existing contemporary development methods of information systems that are based on enterprise modelling do not suit for the transformation of business into knowledge-based

From the knowledge management point of view, the conception of the Knowledge-Based Enterprise embodies the vision of the more mature and more advanced enterprise and is the step towards intelligent enterprise systems. Advancement is seen here as the high formalisation degree of the knowledge management activities which results in the more efficient management and automation of business process and knowledge processes in the

various relationships of these domains.

The formal description of the Enterprise Knowledge Model *M* can be expressed as the Cartesian product in the following way (Gudas, 2008):

$$M = (T) \times (K) \times (B) \times (R) \tag{5}$$

where *T* = information technology, *K* = knowledge, *B* = business process, *R* = business resources.

For the completeness of the model, *resources* (*R*) component was introduced into the model, as we consider knowledge as separate, but integrated enterprise aspect in contrary to the classical enterprise modelling methods which analyze knowledge alongside with other business resources.

This means, that each enterprise knowledge item *m* ( *Mm* ) in Enterprise Knowledge Model *M* is related to the appropriate business process *b* ( *Bb* ), knowledge *k* ( *Kk* ), resources *r* (*r R* ) and information technology *t* ( *Tt* ). To put it in other terms, the enterprise knowledge model *M* item *m* is identified by a set of identifiers:

$$m(t; k, b; r; l) \in M \tag{6}$$

where *l ( Ll )* is time period index.

The Enterprise Knowledge Model *M* is composed of interrelated items *m* and enables modelling a knowledge-based business, as it considers enterprise modelling knowledge (identifier *k*), business processes (identifier *b*), IT (identifier *t*), and their interactions. Each aspect (*b, t, k*) is modelled into the 5 levels of detail in the Enterprise Knowledge Space (Fig. 20).

In Fig. 28, the Enterprise knowledge structure (subsets of knowledge) is presented by class diagram (UML).

Consequently, Enterprise Knowledge Base contains integrated knowledge about three enterprise domains: business (*B*), information technology (*T*) and knowledge (*K*), as well as various relationships of these domains.
