A Little Semi-round Retrospective

摘要

When we founded Sigmas (Special Interest Group on Modeling and Simulation) at the Association for Information Systems and its EOMAS workshop 15 years ago, under the leadership of Professor Joseph Barjis, this was the time of the final penetration of object-oriented paradigm into the area of building large software applications. Indeed, software analysis and design methods at that time had already assumed that software engineering processes begin with the description of requirements, but finding, verifying, and validating these requirements was considered as something that did not belong to software engineering techniques, because the software engineer must get it ready from other specialists. However, we have learned from our experience that this is not an accurate statement and that the requirements engineering must be part of software engineering, more specifically that software engineering has an essential intersection with business engineering and management consulting. Over the past years, the importance of this kind of analysis and prototyping of information systems grew as compared with the writing program code. Also, agile methods do not even assume that the requirements are accurately identified at the begin of the software development life cycle.
