A Model for Enhancing Tacit Knowledge Flow in Non-functional Requirements Elicitation

摘要

Elicitation phase includes features focused on the experience and knowledge of the people to support the capturing and tracing of the business/user requirements, functional requirements, and Non-Functional Requirements (NFR). In this phase, the stakeholders may belong to the same or different organizations and, therefore, their vocabulary and terminology used in NFR expression can be diverse, habitually depending on roles, experience, perspectives and levels of knowledge. This document focuses on the modeling of tacit knowledge flows of the stakeholders involved in the NFR elicitation process. The components of the MERliNN framework are presented, which strengthens a conceptual relationship between the disciplines of Knowledge Management and Requirement Engineering. The TCER core allows to visualize the direction of tacit and explicit knowledge flow in four scenarios of NFR elicitation. We present the description of the first scenario of knowledge instauration and its validation by case study.
