Representation of business processes at multiple levels of abstraction (strategic, tactical and operational) during the requirements elicitation stage of a software project …

Abstract:

This thesis aims at helping software engineers and business analysts to better model business processes when those models are meant to be used: for software requirements specification, and for functional size measurement purposes. The research goal of this thesis is to contribute to the representation of business processes for its use during the requirements elicitation stage of a software project. To achieve this goal, two research objectives are clearly defined: 1. To propose a novel modeling approach that generates business process models intended to be used in a software requirements elicitation activity. The modeling approach should not significantly increase the complexity of the modeling notations used to represent the business processes; and it must allow the active participation of the various stakeholders involved in a typical software project in order to represent, in a consistent and structured way, their needs and constraints. 2. To develop a procedure to measure the functional size of a software application from the business process models representing it. This measurement procedure should be compatible with the COSMIC ISO 19761 standard; and it should be able to be used independently of the modeling notation used to represent the business process. To achieve the first objective, this thesis proposes a novel modeling approach (coined BPM+) that models business processes at three levels of abstraction: strategic, tactical and operational. An a priori version of BPM+ was designed based on the findings of the literature review. This a priori version was iteratively refined through a pilot case study in industry, a series of …
