“…It is important to remember that the model is a customisable tool, providing an extensive set of configuration parameters that, once calibrated, describes the project or organisation in particular. This is a common feature in most of the simulations models found in the literature [65], [73], [74]. Nevertheless, the results of the experiments presented in this paper were included in the expert survey to validate the model behaviour.…”

Abstract.Context: This paper is developed in the context of Usability Engineering. More specifically, it focuses on the use of modelling and simulation to help decision-making in the scope of usability evaluation. Objective:The main goal of this paper is to present UESim: a System Dynamics simulation model to help decisionmaking in the make-up of the usability evaluation team during the process of usability evaluation. Method:To develop this research we followed four main research phases: a) study identification, b) study development, c) running and observation and finally, d) reflexion. In relation with these phases the paper describes the literature revision, the model building and validation, the model simulation and its results and finally the reflexion on it.Results: We developed and validated a model to simulate the usability evaluation process. Through three different simulations we analysed the effects of different compositions of the evaluation team on the outcome of the evaluation. The simulation results show the utility of the model in the decision making of the usability evaluation process by changing the number and expertise of evaluators employed. Conclusion:One of the main advantages of using such a simulation model is that it allows developers to observe the evolution of the key indicators of the evaluation process over time. UESim represents a customisable tool to help decision-making in the management of the usability evaluation process, since it makes it possible to analyse how the key process indicators are affected by the main management options of the Usability Evaluation Process.

“…A weakness noted in the earlier studies, e.g. [9] and [10], was the absence of the consideration for other common dynamic factors in the software project, such as addition of personnel to the team. In order to include this factor in the study, we can use the ProjScout model of Brooks's Law that incorporates the effects of personnel numbers on communication overhead, training overhead and productivity [13].…”

“…This component directly impacts the rate of flow between each of the subcomponents of the SDLC process, defined as productivity rate and, therefore, the total project effort. The Software Defect component from [10] shows the impact of software defects on the flow through the SDLC process. A feedback loop helps to model the way discovered defects would cause the defective component to re-enter the development and testing phases of the SDLC.…”

Abstract-This research study has utilized an experimental design method to evaluate the impact of integrating process work flows, personnel factors, and rework into a dynamic software process simulation model and its implication for software project managers to respond quickly and correctly to changes that are occurring throughout the software development process. The failure rate of software project has remained high due to the failure to effectively manage the dynamic risks that are present throughout the software process. Current risk management methods, project estimation tools and models in existence have not met the need for continuous re-evaluation of projects as unexpected events occur. Many of the unexpected project events can be quantified and represented in a project plan and thus a simulation of the software process can model the effects of those events on the project outcome. The results of the study showed that extending existing models as input to the software development process and parameterizing the change factors and the project profile within a simulation can provide estimation of the effects of dynamic project changes on the outcome of software development projects in terms of effort and completion time.Index Terms-Estimation, simulation model, software development process, software development project management.

Software process simulation models (SPSMs) that are based on descriptive process models offer the executability that can demonstrate dynamic changes of software processes over time. Verification and validation (V&V) is critical in SPSMs for guaranteeing the quality and reliability of models. V&V of dynamic software process models is more complex and challenging than for static software process models. This work systematically summarizes and maps V&V studies in SPSM to provide guidelines for future research and practice. Specifically, this study aims at identifying the focus of research on V&V, the methods used for V&V, and how to implement V&V of SPSMs in software engineering research. We conducted a systematic mapping study on studies of SPSMs that report on their V&V activities. Under the guidance of a V&V meta‐model for SPSMs, we study four research questions about V&V process. We identified 107 primary studies from a pool of 313 papers on SPSMs until 2021. There are two main results of our study. The first one presents the relationship between quality aspects of SPSMs and the V&V methods to assure them. The second result reveals the relationships among the modeling process, three modeling steps, five quality aspects, and 10 V&V methods. Generally, researchers do not pay sufficient attention to V&V, as 65.8% ( ) failed to mention or elaborate on their V&V process. We systematically summarize and map the state‐of‐the‐art V&V research in software process modeling field to support modelers' practice and improve their V&V process.
