Abstract

Quality systems by prototyping M. Blackmail", M. Jeffreys^ Partnership Ltd. Bank Chambers, 68a High Street, ^Jeffreys Systems PLC, Jeffreys House, 21 Normandy Street, 1.0 INTRODUCTION This paper describes a methodology which evolved in the 1970's and 1980's for the development of commercial data processing systems on interactive minicomputers. It was then named Interactive Staged Enhancement (ISE) but it should be seen as a variant of what is now called Evolutionary Prototyping. It worked successfully in a commercial software house environment where meeting cost and time deadlines was essential and where maintainability and modifiability of finished systems was crucial. A description of ISE was first published in Jeffreys [1]. The relatively low cost and speed of prototyping methods, as well as their ability to readily satisfy user needs, is well known, but they are widely criticised for lacking a respectable methodology and for being difficult to quality assure.
