abstract software entity, and accidental tasks, the representation of the abstract entities in programming languages and the mapping of these onto machine languages within space and speed constraints have made the accidental tasks inordinately hard, such as severe hardware constraints, awkward programming languages, lack of machine time. How much of what software engineers now do is still devoted establishing software requirements • Growing software organically, adding more and more functions to systems as they are run, used, and tested”Who said it?Frederick Brooks Jr. • Joined IBM in 1956 • Manager
