This week's discussions at Clarity First revolved around a thinking tool that some of you will have heard of.

If you have ever worked with consultants, then it is most likely you are familiar with the term MECE.

Depending which firm you have been working with, you will have heard it described as either Mutually Exclusive and Collectively Exhaustive (McKinsey and others) or Mutually Exclusive and Covers Everything (BCG and no doubt others also).

I have a hankering for a different vernacular, NONG, which stands for two things in Australian parlance: No Overlaps, No Gaps and an insult which was hurled freely at children when I grew up.

In Australian slang, to be a nong is to be a bit of a fool.

To my mind if you can master this most useful and frankly tricky tool you are by no means a fool. Quite the opposite in fact.

In our discussion we were using five different techniques to frame communication that passed the MECE or NONG test.

This meant that the ideas we crafted into a clear hierarchy had to not only be relevant to the main message but include a complete set of supporting points that furthered the discussion.

For example, if our ‘so what' was ‘We should buy business X to increase our market share', we used the five techniques to carefully identify whether there were any gaps or any overlaps in our thinking.

In applying this to one example we discovered after our initial drafting that we had six supporting points, and that one of them could easily sit beneath another in the hierarchy.

As we discovered, although the concept is pretty easy, unearthing the thinking problems within it so we can deliver communication that is not just clear, but engaging and insightful is another matter.


I love what I do.

I help senior leaders and their teams prepare high-quality papers and presentations in a fraction of the time.

This involves 'nailing' the message that will quickly engage decision makers in the required outcome.

I leverage 25+ years' experience including

  • learning structured thinking techniques at McKinsey in Hong Kong in the mid 1990s before coaching and training their teams globally as a freelancer for a further 15 years
  • being approved to teach the Pyramid Principle by Barbara Minto in 2009
  • helping CEOs, C-suite leaders and their reports deeply understand their stakeholder needs and communicate accordingly
  • seeing leaders cut the number of times they review major papers by ~30% and teams cut the amount of time they take to prepare major papers by ~20%*
  • watching senior meetings focus on substantive discussions and better decisions rather than trying to clarify the issue

My approach helps anyone who needs to engage senior leaders and Boards.
