What Users Do: Sa&D With The Atsa Method, Robert B. K Brown, Ian C. Piper

Faculty of Engineering and Information Sciences - Papers: Part A

Incomplete or inefficient elicitation, comprehension and transmission of client requirements are all sources of information system (IS) failure rates. Requirements may be missed, misunderstood or miscommunicated for the lack of a single, consistent, informing theory. Structured requirements elicitations techniques impose time delays. Cursory techniques can fail to reach any mutual understanding with the stakeholder. Formal methods can fail to cope with non-functional requirements and coder-oriented methods can put the cart before the horse, delivering something other than required. Agile methods can deliver hasty product, cobbled to meet first-cut requirements, perhaps justified by a notion that users cannot reach stable conclusions.
