Research On Knowledge Transferring Model And Strategies For Requirement Engineering

Requirement engineering is being taken seriously among software project management and is the hot spot of many scholars of this field. With the rising of knowledge engineering, there are many new researching methods and means are being applied in requirement engineering. We just stand by the specialty background of requirement engineering, and research on the knowledge transferring under this special background. At same time, we offer some strategies to make knowledge transferring more fluent between two sides of requirement engineering.We found out the key point for success of requirement engineering is to execute fluent knowledge transferring, which is start point of this thesis. We classified the knowledge of two sides into knowledge type structure and their knowledge cognitive structure. From the point of requirement engineering, we discussed the knowledge context, which offered theoretical foundation for the establishment of knowledge transferring model and representation of execute strategies. We first created requirement engineering knowledge transfer conceptual model, to form the main structure of this thesis.We continue to discuss on the knowledge transferring model for requirement development and requirement management, which revealed the key segment and inside mechanism, and also theoretically motivate the correct knowledge transferring in requirement engineering. The procedures of requirement development knowledge transfer are knowledge elicitation, knowledge analysis, knowledge specification and knowledge verification, we created requirement development knowledge transferring model based on these four stages. According to this conceptual model, we creatively offered the characteristic of requirement knowledge transferring is a kind of two-way transferring. Requirement management knowledge transfer consists of control management of knowledge modification, edition management of knowledge cohesion, traceability management of knowledge transferring and information management of knowledge state. We created knowledge transfer model for whole requirement management based on these four aspects. According to this model, we creatively offered the characteristics of requirement knowledge transferring are knowledge traceability and knowledge back-traceability, as while as knowledge spiral rising and knowledge learning.
