Abstract :
The effects that two methods of eliciting requirements and two types of task structure have on user involvement and analysis phase success are explored. A 2×2 factorial design compares a prototyping process to data-flow diagramming using a CASE (computer-aided software engineering) tool. Each method is used by one analyst and one user to elicit requirements for a decision-support system task or a transaction-processing system task. Some differences between treatments are found, although due to small sample size, results are not conclusive. Some concerns regarding future research studies that examine differences in systems development methodologies are also discussed
