On "The Right" Software

2 Summary • Boehm [Boehm81] is credited to have formulated the " Two Rights " of software: – the problem of getting the right software – and – the problem of getting the software right. • The development processes needed – to achieve software that is right, to us, * requires that a proper study of the application domain * be done before a serious requirements study is attempted; and – to achieve the right software, * that is, software that is correct, to us, * requires that a proper engineering degree of formalism * be applied to the entire development process; – that is, that we re-interpret classical development processes [Spiral-Model-Boehm-1988]. 3 • We shall in this paper focus only on the issue of obtaining the right software. • In this talk we shall outline – what we mean by a proper study of the application domain – and how it influences the requirements development.
