PurposeThis research paper takes an interdisciplinary approach, drawing from empirical data, to explore the relationship between organisational change management and strategic leadership to promote growth in value-driven, membership-based organisations through a qualitative multi-case-based analysis and to provide a discussion on the philosophies and practices of leadership teams which underpin successful organisational change within such not-for-profit organisations.Design/methodology/approachEach participating organisation had 700+ members, had previously experienced prolonged periods of auditable membership growth and employed distinctly different organisational models to facilitate growth. A qualitative multi-case study approach was adopted informed by 32 interviews with eight leadership teams. A thematic analysis provided a comparative review of responses.FindingsAll case study organisations emphasised the significance of strategic leadership teams and clearly communicated vision and flexible organisational structures as central to their strategic planning and subsequent growth. This builds on previous research which has explored organisational change in not-for-profit organisations and strategic leadership in not-for-profit organisations, which explores the strong linkages between the roles and functions of strategic leadership, organisational structures designed with the adaptive capacity to manage continuous and convergent change and their impact on sustained growth. Such linkages are more specifically supported by extended tenure of office for those in senior leadership roles, clear delineation of roles and responsibilities, the adoption of an outward growth-oriented focus and adaptable structures that encourage wider participation in leadership and management functions for the fulfilment of the organisation's mission. Most significantly, these organisations plan with change and growth in mind.Practical implicationsThe findings of this research have transferable value to other not-for-profit, membership-based, value-driven organisations as well as other faith-based organisations, which will help to provide future linkages between leadership structures, decision-making and organisational design and its impact on the not-for-profit organisations' capacity for sustained growth.Originality/valueThis research challenges previous conceptions on UK church growth trends and observes that all the case organisations presented different organisational structures which were intentionally designed, context specific and developed by leadership teams with sustained growth in mind. Results from psychometric testing of participants confirmed that senior leaders of large value-driven organisations that have demonstrated a capacity for sustained growth are consistently likely to exhibit leadership characteristics which demonstrate a balanced capacity for personal humility and a committed resolve or professional will, which is also reflected in a pragmatic-type leadership style, building on previous psychometric testing research in this context.
