Stephen Warrilow,
Associate Director & Principal Consultant

Stephen has 25 years cross-sector experience with over 100 companies as an independent resource providing specialist support for directors and senior managers delivering large projects and programmes with a significant change element.

Having spent many years observing closely what works and what doesn't he came to realise that the single biggest reason for the astonishingly high 70% failure rate of all significant change initiatives has been the over-emphasis on process rather than people, and specifically the failure to take full account of the impact of change on those people who are most impacted by it

It was this realisation that motivated Stephen to develop and create a large online curriculum of change leadership and change management training and educational material comprising the best of current thought leaders and change practitioners in the field together with original material all based on practical experience.


These online materials are accessed globally and used by thousands of business leaders, senior managers and post-graduate business students.

Stephen’s resources are thoroughly grounded in practical experience where he focuses on the areas outside of the scope of traditional programme, project and change management methodologies.

Stephen sees change management as a combination of insights, understandings, tools and processes that he brings to organizational leaders and senior managers.

"I do not sell change management - I sell the benefits of what change management delivers!"

He does this to help them achieve their strategic objectives and realize the personal and organizational benefits of these objectives, and all in the context of major change. It involves:

  • Diagnosis - of root cause issues
  • Development - via executive support, mentoring or training
  • Delivery - to ensure realization of the anticipated benefits

Stephen's clients are senior executives who are:

  • Stuck between their strategic vision and a successful programme implementation
  • Anticipating or experiencing the impact of major change and areas of resistance
  • Experiencing log-jams
  • Seeking diagnosis of root cause issues and recovery options

Stephen describes his relationship with his clients as that of "Trusted Advisor and Deliverer", it is a relationship where Stephen is seen as a resource who understands the "people issues", looks after his client's interests and helps them get results.

"I help you lead your people through change, put it all together and manage the whole messy business!"

Michael Msebenzi
Chief Africa Representative

Michael has worked as an investment banker at ABSA Capital (majority shareholder is Barclays Plc) in Johannesburg, South Africa. There he worked both in leveraged finance as well as corporate finance during the difficult global recession period.

At ABSA Capital, Michael's focus was primarily on South African listed (on the Johannesburg Stock Exchange) companies such as SAB Miller, Vodacom (part of the Vodafone Group), Sun International, MTN, Massmart (part of the Walmart Group) and similar companies.

Following his stint in banking, Michael formed a commodities trading business along with four other partners that focused on Sub-Saharan Africa. The business allowed Michael to further his grasp on the finer workings of the vast and varied African economy. While previously dealing with listed well regulated companies, Michael had to learn very quickly how the unlisted market functions. Over a three year period, he developed his network and advanced his knowledge of commodities, particularly gold and coal.

Michael joined the AC team in 2013 where he has served as the team's Chief Africa Representative. The bulk of his work centres around client acquisition, both buy and sell side, as well as deal execution in the commodities space.

Michael studied at The University of Cape Town where he obtained a Bachelor of Business Science (BBusSci) Financel Honours.
