Description: Big rocks, pebbles and sand: the classic prioritisation metaphor — and the coaching conversation it unlocks about protecting the 20% that creates 80% of the value.

From a live TESS coaching session with trainer Jamie Chambers · captions included

“If these are the 20% of your activity that generates 80% of the value — what are you doing to make sure nothing gets in the way of that?”

The most visual prioritisation tool there is, told by Jamie on camera, followed by exactly how a coach turns it into a conversation. These clips come from live sessions that feed into the CMI Coaching unit our learners complete.
