Requirements Engineering using the Lean methodology
Nowadays, due to the advance of the technology and easy access to information, almost anybody has the opportunity to build virtually any software product or service and address it to the global market. Despite its relatively short history, the software industry has flourished attracting a huge interest and effort into developing, testing, marketing, and selling its products, amongst many other related activities. The Requirements Engineering (RE) [1,2] is a crucial part of the software development process. It has been proven, both in the literature [3,4,5] and from our experience in ISDC, that functional misunderstandings or inaccurate business activity models imply far smaller costs when discovered during the requirements development or the grooming stages than when their effects appear after the software goes into production.
