The SIMPLE. Transformation Framework™ was developed through a five-year national research and development programme led by Growth Development, bringing together a group of founders with deep expertise across leadership, organisational culture, behavioural science, system change, and community-led development.
Together, this collective shaped the early concepts, testing environments, and applied learning that led to the creation of the SIMPLE.™ Leadership Knowledge Set and the SIMPLE.™ Transformation Method. Their combined experience across public, private, and community sectors played a critical role in grounding the Framework in real-world challenges and ensuring it could be applied across diverse contexts.
Melanie Bedggood, Principal of the Transformational Change Institute, served as the R&D lead across the programme and is the principal originator of the SIMPLE.™ Transformation Framework. Melanie continues to steward the evolution, integrity, and global application of the Framework through her leadership of the Institute.
Today, the founders’ contributions remain embedded in the Framework’s principles and design, forming the foundation for a methodology that supports leaders, teams, and organisations to navigate transformation with clarity, confidence, and capability.
