Vijay Kumar Sethi, James T. C. Teng · INFOR Information Systems and Operational Research · 1988
Effective information requirements analysis (IRA) is critical for the success Of application systems. Literature has mainly defined the contingencies under which specific IRA methods are most effective for determining the content of information. This paper shows how IRA methods can supplement each other, instead of being viewed as alternatives. A process for combining IRA methods is developed. Resolving differences between Decision Analysis and Data Analysis by developing different kinds of Prototypes is presented as an integrated framework of IRA. Case studies illustrating this approach are included. The paper extends research in two areas: IRA and Prototyping.
