Sustainability assessment of the application of software architecture standards : integrating a KPI model with sustainability decision maps via an industrial case study

Abstract

This thesis addresses the integration of a Key Performance Indicator (KPI) framework into the Sustainability Assessment Framework (SAF) Toolkit to enhance its capability for assessing the sustainability of software architecture standards. The research aims to develop a cohesive framework that combines the KPI model by Fatima et al. [3] with the SAF Toolkit by Lago et al. [11] to provide a comprehensive tool for sustainability assessment. Through an industrial case study, the research examines the practical application of the proposed framework and its utility in real-world settings.

The study is structured around two primary research questions focusing on the development and application of the framework, branching into potential challenges, benefits, and validation of the results. The research employs a multi-phase methodology, including knowledge gathering, framework development, case study, and validation through expert interviews and a focus group.

Key contributions of this research include the development of an integrated framework, practical insights from its application in an industrial setting, and recommendations for overcoming challenges in KPI implementation. The findings emphasize the framework’s ability to enhance sustainability awareness and decision-making among software architects, providing detailed insights and supporting informed design choices.
