Most leadership problems aren't about skill, they're about maturity.
Knowledge and competence are necessary but not sufficient. The leaders who fail to navigate complexity, transform cultures, or sustain performance under pressure are almost always operating from a level of mental maturity that isn't adequate for the demands they face. The Maturity Profile measures that and charts the path forward.

Assessing A Leader's Sophistication
When assessing leadership ability, at the most senior level of an organisation, what's most important is to define whether your leaders are sufficiently sophisticated to handle the complexity they're facing.
The challenge is that most assessments are descriptive not developmental. They measure typologies, personalities, or strengths. Such approaches can't predict whether a leader can handle complexity and therefore they tell you very little about whether a leader will succeed or fail.
Developmental assessments in contrast, are much more useful in predicting future success . They provide you win an instant insight on how to improve your leaders so they can succeed.
The hidden cost
Inability to adapt to change · Unable to cope with complexity · Ability to drive organisational change · Resilience · Potential to take on challenges · Meeting your developmental ceiling · Development that doesn't stick · Complexity without capacity · Succession that misses the point

How do we assess maturity?
The Complete Maturity Report is an online questionnaire. The distribution of your answers undergoes multiple statistical analysis to generate a preliminary level with your leading and trailing edges.
A highly trained, experienced and certified scorer evaluates the responses as they relate to each other and assesses the profile as a whole. Our scorers go through intensive training with practice and a final exam to become certified.
The results of your Complete Maturity Report are provided in a detailed report, benchmarked against two populations (general public and leadership professionals) and feedback is provided by an experienced Complete Practitioner to explain your results and development journey with you.
Your journey to the next level
The Complete Maturity Report is the key to unlocking potential and developing your leadership vertically.

Participants complete a structured sentence completion exercise designed by Susanne Cooke-Greuter. There are no right or wrong answers, the responses reveal how the individual constructs meaning and makes sense of their experience.
Leadership selection & succession
Identify candidates with the developmental capacity to succeed in your most complex and demanding roles, not just track record and competence, but mental operating system to navigate their future challenges.
Best for: Boards, CHROs, CEOs
Coaching and development focus
Use the Maturity Profile to give coaching a clear direction. Rather than working on behaviour change at the surface, coaching can target the specific developmental edge that will unlock new levels of leadership capacity.
Best for: Executive coaches, L&D leads
Culture transformation
Transformation requires leaders who can operate from multiple perspectives, holding multiple, competing views simultaneously and leading change without imposing their own frame. The Complete Maturity Report identifies who those leaders are.
Best for: CEOs, transformation leads, OD practitioners
"Developing maturity delivers a quantum shift in a leader's mental complexity and capability."
The Complete Maturity Profile draws on the most rigorous framework for adult development available, built with based on a very extensive academic literature from Piaget, Loevinger, Kegan, Torbert, O’Fallon, Cook-Greuter and Ken Wilber.
Clients have used the Maturity Profile to identify developmental bottlenecks in senior leadership teams, to design more targeted succession processes, and to give coaching a precise developmental direction.
Dr Alan Watkins' 4D Leadership model, which underpins much of Complete's work, maps directly onto the maturity framework.
Leaders who have read 4D Leadership often find the Maturity Profile the natural next step in making the concepts personal and actionable.
