LEARNING OUTCOMESYou will:1. Find out about the different purposes of a specification2. learn about different forms of specifications3. use specifications to develop ideas and evaluate products
MYTHS ABOUTSPECIFICATIONSOnce written they can’t be changedOnly one type of specificationNo evidence needed to support a specificationDon’t’ start to write it until you have all of the answersOnly one specification is needed

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.
