PurposeThe aim of this study is to report and reflect on the development of a tailored executive education programme rooted in state-of-the-art research and focused on enhancing and embedding project leadership competences in a multi-national project-based organisation.Design/methodology/approachThrough a detailed description of an example of a leadership development programme, the paper reflects on the learning journey. Drawing on research in management education, leadership and project management competence development, the authors present the rationale, design, delivery and participant and organisational experiences.FindingsReflections on the learning journey identify five key points: a) the fundamental role of a programme champion, b) the importance of balancing rigour and relevance in executive education programme design, c) the importance of attending to the milieu of the clientele in terms of culture, demands and where they are in terms of their learning journey, d) the significant role that reflection can play in personal development and e) the competences necessary for project leadership.Research limitations/implicationsThis paper reflects on a single programme for a single organisation and is therefore at risk of being idiosyncratic and not generalisable. This is indeed a limitation. However, the authors are all experienced in delivering executive education – and therefore can use those experiences to view the reflections. Many of the considerations noted here resonate with other programmes (both in support and through experience of omission having detrimental effects).Practical implicationsThe paper provides new insights into developing enduring and effective leadership competences in complex project management, i.e. one that has a lasting impact on the organisation and is recognised to provide benefits. The reflections on how the authors charted a course and embarked on a journey are deemed of relevance to academics and industry.Originality/valueThe paper provides, for both industry practitioners and academics, new insights into effective leadership development in complex project management, one that has a lasting impact on the individual and the organisation and is recognised to provide benefits.
