Edgecumbe’s Primary Colours® Model of Leadership
A simple and practical leadership language
What is the Primary Colours® Model of Leadership?
The Primary Colours® Model is Edgecumbe’s proprietary model of leadership. Developed over 25 years of research led by Edgecumbe founder Professor David Pendleton, it defines the tasks leaders must perform in order to create the conditions for sustained success. By mapping the three domains in which leaders work – the strategic, operational and interpersonal domains – it provides a simple, memorable and actionable description of WHAT leaders need to do.
Over 100 years of research suggests that WHAT leaders do is consistent across geographies, industries, organisations and functions. However, HOW leaders need to work varies a great deal, based on context. We think that’s why traditional competency and behavioural models fall short of their aims.
The foundations and development of the model are set out in Leadership: No More Heroes (2021, 3rd edition) by Professor David Pendleton, Professor Adrian Furnham and Jon Cowell (Edgecumbe’s CEO).
How do we use it?
The model provides a common language and set of criteria for assessing and developing leadership at all levels for individuals, teams and whole organisations. Its focus on tasks makes it easy to translate business challenges into leadership challenges and to define WHAT WE NEED TO DO as leaders to meet our specific challenges.
Because the model focuses on tasks it is often overlaid on existing competency or behavioural models to provide an over-arching framework for leadership. It can then be used to assess leadership capability to frame the curriculum for leadership and team development programmes, and as the core architecture for leadership talent processes.
Furthermore, the underlying structure of the model is consistent with the psychological factors which are most influential in shaping an individual’s leadership strengths and weaknesses; as such, it supports a leadership assessment approach that reflects enduring differences between people. Therefore, it helps to clarify the kinds of leadership role for which an individual is fundamentally well-suited, and those in which they are never likely to thrive, and supports the creation of complementary leadership teams.
Finally, because it is based on broad leadership tasks rather than detailed competencies whose importance depends on context, it enables benchmarking of leaders across functions, organisations and industries.
