Sustainable. Strategic. Success

Change is inevitable, but success isn’t. Research shows that up to 70% of business change initiatives fail—but not with the right approach. Incremental Change Management Maturity Model (ICM3) helps your organisation take its first step toward a seamless, sustainable transformation.

ICM3 is a simple yet powerful framework designed to assess the real maturity of your team or organisation. It’s the perfect starting point before diving into more complex maturity models. Whether you’re managing large-scale projects or incremental changes, ICM3 provides a clear path to ensuring your organisation is prepared for sustainable, successful change. 

At this stage, every project in your portfolio has a clear foundation. Core documents—like a project charter, plan, budget, and risk assessment—are standardised and accessible through a central management point (e.g., your PMO). It’s not exhaustive but lays the groundwork with essential details for consistency.

Take your documentation to the next level. At this maturity stage, the format and content of all project documents are consistent and comprehensive. Your teams follow established processes and accountabilities, ensuring that projects across the board deliver regular, reliable reporting at both the individual and portfolio level.

Ready for automation? Here, semi-automated reporting tools streamline performance tracking, ensuring deadlines are met, and compliance is achieved. Your team knows how to use central reporting tools effectively, and the data speaks for itself: on-time, accurate reporting for confident decision-making. Ensuring sustainable success.

When you’ve mastered all aspects of Better Practice, your organisation is prepared for greater complexity. Best Practice integrates full-scale compliance, tool utilisation, and in-depth proficiency, positioning your team to take on more advanced change management models confidently. Achieving Operational Excellence.

Aarti Yacha

Program Management 

“Super dynamic consultant with a strong foundation in Prog/Project Management and Business Change. Great energy and a fantastic Prog. Manager to work with. Rarely do I get to see someone within this capacity documenting every practice followed within program governance, and it doesn’t just stay within those documents; it’s in practice, too.. to a tee, with 100% repeatability. This adds great value, especially when it’s global operations. The consistency in the way he runs the show, proves the years of experience and efforts that have gone into building those practices within one’s self. Hats-off!

Marcellus is a master in contextualising change management methodologies, processes and best practise to meet the needs of the situation, bringing them to life in such a consumable and engaging way encouraging, supporting and empowering key stakeholders to learn, embrace and become advocates thus creating team and organisational capability and capacity.

I’ve had the pleasure of working with Marcellus for almost 2 years now and I can honestly say within that time, he’s been someone that’s proven to be highly knowledgeable in many area’s. On many occasions, Marcellus has been the voice of reason and guidance to much success. I can say I’ve learnt a lot over the years and implemented these lessons to better myself.

Looking forward to many more fruitful moments together.”

Jody Randall

“Marcellus are, without a doubt, one of the most talented Program Managers I have worked with. His level of professionalism, detail and knowledge are exactly what supports a program team to deliver to the highest level.

Marcellus not only understands the principles of Change Management to support the Change Managers on the program but uses that knowledge to challenge them to think of creative ways to ensure engagement, buy in and successful adoption.

It will be my pleasure to work with Marcellus again in the future.”

Mike Crow

IT Manager, Atos

“Marcellus is a TRUE THINKER . He plans for things the rest of us may overlook, then provides realistic solutions to each scenario. As a result, he is always prepared. Marcellus is driven and focused, and has become a natural leader in project and change management. Combining his 30+ years of experience with his creativity and people skills, he’s a go-to person for implementations, large or small.”

David Wilkinson

Editor, Oxford Review

“Not every professional is interested in making sure that they are right up to date with the latest research and thinking in their core area. However, Marcellus is one of those rare people who takes their professional responsibilities and development seriously and who mixes practical experience with proper evidence and research. Marcellus is professional, knowledgeable and with a real concern for not only making sure that his work is evidence-based but that his deep knowledge is right up to date with the very latest research and evidence.”
