How can you improve your as-is models? Requirements analysis methods meet GQM

Abstract

Context & motivation: To develop information systems providing high business value, we should clarify As-is business processes and information systems supporting them, identify the problems hidden in them, and develop To-be information systems so that the identified problems can be solved. Question/problem: In this development, we need a technique to support the identification of the problems, which can be seamlessly connected to the modeling techniques. Principal ideas/results: In this paper, to define metrics to extract problems of the As-is system, following the domains specific to it, we propose the combination of Goal-Question-Metric (GQM) with existing requirements analysis techniques. Furthermore, we integrate goal-oriented requirements analysis (GORA) with problem frames approach and use case modeling to define the metrics of measuring the problematic efforts of human actors in the As-is models. This paper includes a case study of a reporting operation process at a brokerage office to check the feasibility of our approach. Contribution: Our contribution is the proposal of using of GQM to identify the problems of an As-is model specified with the combination of GORA, use case modeling, and problem frames.
