This paper reflects a decade-long journey of industrial practices on requirements inspection in the Japanese software industry, and proposes a ELFIEP (Evolutionary Lifecycle Framework for Industrial Engineering Practice). We have published two papers in RE’13 and RE’14. The first paper introduced an industrial practice of SRS (Software Requirements Specifications) inspection system in a software company. The system means a set of inspection items: inspection processes, techniques, and supporting tools. In the second paper, to encourage wider industrial adoption of requirements inspection systems, we have proposed a methodology for designing requirements inspection systems. We call it RISDM (Requirements Inspection System Design Methodology). RISDM has been recognized in professional communities in Japan. A number of software companies adopted the methodology, and then started to operate the designed inspection system in each company. In this paper, we take a retrospect of the journey of RISDM. The journey refers to the practices before and after the birth of RISDM. Learning from the journey, we propose the ELFIEP as a generic framework of the evolution of engineering practice, and discuss insights gained from the journey and the framework.
