What we promise we deliver, keeping our commitments means everything to us.


We focus on critical issues, making a difference where it adds value to individuals.


We believe keeping it simple helps ensure execution is highly effective.


We inspire managers to become world-class – to be the manager their team and organisation deserves!


How good you want to be is more important than how good you are today.

Not Another Training Company

We observe and support managers where it matters the most – on the frontline.

We understand that in the world of remote and multi-unit management, a sustained improvement in performance is only achieved through the consistent application of new and better behaviours and high-impact activities.

While workshop-style sessions have a place in the overall programme structure, we appreciate that real learning happens beyond the walls of any training workshop, back in the realities of the job. We observe and support managers where it matters the most, on the frontline as they carry out their role, helping them embed the skills and behaviours they have learnt.

It’s what we do.

Who do we work with?

MMU works with organisations of all sizes but specialises in:

  • SMEs (including owner-operators).
  • Large businesses that are looking for tailored solutions and/or competencies they don’t have in-house.

Our Team

A team with one driving focus. To develop managers to be the best they can be, because EVERYONE deserves to have an outstanding manager.

We all understand operations because we’ve all been there; on the frontline, working with diverse teams to make a difference and drive performance. Our practical experience and know-how, coupled with academic research and insights, helps us to take an objective and fresh perspective on the organisation and the capabilities of its managers.
