(a) ‘User needs are often hard to identify prior to gaining experience from the running of a system. It is therefore a mistake to adopt the philosophy of designing the system to meet user needs. It is better to design and implement a “rough and ready” version of a system to see how users take to it. This can then be systematically amended to remove its shortcomings. The process of design becomes iterative rather than linear.’ What is to be said for and against this view?

(b)
‘If the people who were going to use the computerized information systems were involved in decisions as to what kind of system was needed and how to design it then better information systems would be produced.’ Do you think this is a desirable and realistic policy?
