Measuring reuse of SAP requirements
Maya Daneva · 1999
Reusing SAP R/3 business requirements has been recognized as the most promising strategy to shorten the time-to-production and increase the quality of the conceptual design in R/3 implementation projects.However, very little research has been conducted to actually quantify and really estimate the results from SAP R/3 requirement reuse the customers have achieved.This paper deals with the identification and the measurement of reuse in the requirements conceptualization phase of the SAP R/3 component configuration cycle.We present a systematic approach based on standard functional size measurement practices.We introduce two key concepts: SAP requirements reuse levels and reuse indicators.The reuse levels serve to classify SAP requirements based on the extent to which the requirements are reused in a R/3 implementation project.The reuse indicators are then built to quantify the requirement reuse the company has achieved.An experimental case study illustrates the applicability of the approach.Finally, some validation issues are addressed.
