Abstract [en]

Background: Since the 1950s explicit software process models have been used for planning, executing and controlling software development activities. To overcome the limitation of static models at capturing the inherent dynamism in software development, Software Process Simulation Modelling (SPSM) was introduced in the late 1970s. SPSM has been used to address various challenges, e.g. estimation, planning and process assessment. The simulation models developed over the years have varied in their scope, purpose, approach and the application domain. However, there is a need to aggregate the evidence regarding the usefulness of SPSM for achieving its intended purposes. Objective: This thesis aims to facilitate adoption of SPSM in industrial practice by exploring two directions. Firstly it aims to establish the usefulness of SPSM for its intended purposes, e.g. for planning, training and as an alternative to study the real world software (industrial and open source) development. Secondly to define and evaluate a process for conducting SPSM studies in industry. Method: Two systematic literature reviews (SLR), a literature review, a case study and an action research study were conducted. A literature review of existing SLRs was done to identify the strategies for selecting studies. The resulting process for study selection was utilized in an SLR to capture and aggregate evidence regarding the usefulness of SPSM. Another SLR was used to identify existing process descriptions of how to conduct an SPSM study. The consolidated process and associated guidelines identified in this review were used in an action research study to develop a simulation model of the testing process in a large telecommunication vendor. The action research was preceded by a case study to understand the testing process at the company. Results: A study selection process based on the strategies identified from literature was proposed. It was found to systemize selection and to support inclusiveness with reasonable additional effort in an SLR of the SPSM literature. The SPSM studies identified in literature scored poorly on the rigor and relevance criteria and lacked evaluation of SPSM for the intended purposes. Lastly, based on literature, a six-step process to conduct an SPSM study was used to develop a System Dynamics model of the testing process for training purposes in the company. Conclusion: The findings identify two potential directions for facilitating SPSM adoption. First, by learning from other disciplines having done simulation for a longer time. It was evident how similar the consolidated process for conducting an SPSM study was to the process used in simulation in general. Second the existing work on SPSM can at best be classified as strong ``proof-of-concept’’ that SPSM can be useful in the real world software development. Thus, there is a need to evaluate and report the usefulness of SPSM for the intended purposes with scientific rigor.
