“…As discussed above and shown in Table , there are considerable number of studies related to knowledge and KM in REP. In fact, although significant research exists regarding different aspects of KM such as knowledge sharing (Maio, ), knowledge creation (Wan, Zhang, Wan, & Huang, ), knowledge conversion (Wan et al, ), knowledge transfer (Shan et al, ), and domain knowledge (Kaiya, Shimizu, Yasui, Kaijiri, & Saeki, ; Niknafs & Berry, ) in requirement engineering, REP, software development, and system engineering, little is known about practical approaches for knowledge assessment and auditing in REP (Wai, Ammuthavali, & Marini, ). There is also a lack of knowledge assessment in REP in the previous research literature.…”
