Intentional Models based on Measurement Theory

Metrics and measures have always been the subject of quite a lot of research works in the Requirements Engineering (RE) community, including about intentional models of Goal-Oriented RE (GORE) such as those of i* . However, using recent developments of the Measurement Theory, in this paper we show that the concept of Measurement Framework (MF) for soft-systems is useful for the analysis of business service systems that need long-term service agreements based on consistent measurements at all stages of their life-cycle (from inception to operation). We show that with two kinds of goals and softgoals based on MF, it is possible to improve (a) the elicitation of functional and non- functional requirements, (b) the structure of the i* models, and (c) the consistency between run-time measurements and the model-based assessments of business services at early stages of RE.
