A Requirements Engineering Process Assessment Model for Small Software Development Organization

Abstract

Requirements Engineering Process Assessment (REPA) was conducted prior to Requirements Engineering Process Improvement (REPI) activities to identify the Requirements Engineering Process area to be improved. The Requirements Engineering Process Assessment methods such as REPM, R-CMM, REMMF, Uni-REPM were available to all enterprises, but they were difficult for most of the small organization because of complexity and consequent large investment in terms of time and resources. In order to conduct Requirements Engineering Process Assessment (REPA) activities with few efforts in small organizations effectively. We have presented a quantitative Requirements Engineering process assessment model based on Quantitative Assessment Model for Software Process Improvement in Small Organization. It was an efficient approach to evaluate the quality of the Requirements Engineering process execution for improvement of the organization Requirements Engineering process maturity. We present Requirements Engineering process assessment results for four software companies, describe milestone compliance score distribution and compliance score distribution for Requirements Engineering assessment items. All these companies reported satisfaction with their participation. Our conclusion is that quantitative Requirements Engineering Process Assessment model is useful in assessment of Requirements Engineering process in small organization and in identifying the strength and weakness of the Requirements Engineering processes.
