In spite of decades of research into high-performance work systems, very few studies have examined the relationship between executive learning and development and organisational performance. In an attempt to close this gap, this study explores the effects of a validated four-dimensional executive learning and development measure on a composite measure of organisational performance. The study is based on ordinal regression analysis with empirical data elicited from 222 executives and senior leaders drawn from a wide geographic region. The theoretical link theoretical between the two variables was established by building on the Activity-Motivation-Outcome concept in order to encapsulate human capital, dynamic capability, resource dependency, social exchange and leader-member-exchange theories. The study reported an overall positive effect of executive learning and development on firm performance and has significant implications for the effective development of executive and senior management capabilities as a means of improving organisational effectiveness.
