The Requirements Enhancement Based on a Problem Domain Model

The paper deals with the problem of the requirements enhancement related to a particular problem domain. New requirements related with problem domain (user, customer study program) are elicited and compared with the old requirements which are documented before. The modified Value Chain Model (VCM-based) framework for the refinement of new requirements, assessment and enhancement of old system requirements is developed and discussed. Enterprise management information interaction is specified as an Elementary Management Cycle (EMC), linking enterprise management function and process by a feedback loop. A modified Value Chain and Elementary Management Cycle model was created to describe management knowledge updating process. Proposed hierarchical modified Value Chain Model and Elementary Management Cycle model allows to structure domain knowledge identification and updating processes.
