The quality of any organisation is one of the most critical factors for sustained success, and how quality is managed and absorbed within an organisation are fundamental to achieving its goals. In the current era of sustainability-driven development, it makes little sense to limit the meaning of quality predominantly to services and products without considering the quality of the organisation itself. International guidelines such as the ISO9004:2018 emphasis quality management as an integral component of organisational sustainability, success, and excellence. The 2018 version of the guideline provides an essential framework to help organisations achieve sustained success and measure organisational maturity across seven critical levels: Context, Identity, Leadership, Processes, Resources, Performance, and continuous improvement, learning and innovation. However, to date, despite its potential, there is limited industry uptake in using such guidelines, a fact reflected in the limited number of publications available on the topic. For professionals in architecture, engineering, and construction management (AECm), this integration is especially relevant. AECm practitioners often operate within large, complex organisations in which they play a critical role in ensuring the organisation’s sustainable and successful future. In parallel with this, a substantial proportion of AECm professionals are self-employed or lead small consultancies, making them directly responsible for the sustained success and quality performance of their own enterprises. Equipping graduates with the knowledge and tools to lead, assess, and continually improve organisational systems, regardless of their career context, is a key element in ensuring that graduates are ‘workplace ready’ and able to support organisational sustainability and quality management. This paper examines the application of ISO 9004:2018 within postgraduate AECm education and presents an applied case study that demonstrates how active learning, project-based assessment, and industry collaboration can enhance student engagement and professional readiness. The findings highlight the value of integrating quality management principles into AECm curricula to align educational outcomes with international standards and to prepare future professionals for leadership in sustainable, high-performing organisations.
