PRODUCTDEVELOPMENTAgile is a software engineering philosophy devised in the late1990s. It is based on the assumption that projectspecifications are likely to change during the productdevelopment cycle. Therefore, rather than creating acomprehensive specification upfront and engineering aproduct to fulfil it, the Agile process treats productdevelopment as a series of short iterative loops, lasting onlydays or weeks.
