I loved my ‘fast fly’ through this book and am realizing how much more I am finding useful by going slowly and preparing these posts for you.

Thank you for encouraging me to slow down!

I am still in the introduction reading about the power and dangers associated with mental models and the concept of blind spots has jumped out at me as worth our attention.

In the Great Mental Models Vol 1, Shane Parrish suggests that we need a latticework of mental models to be maximally effective.

He quotes Alain de Botton from How to Make a Decision

“The chief enemy of good decisions is a lack of sufficient perspectives on a problem”

Taken together these points are a powerful reminder on how to avoid blind spots.

Bring people together who have a variety of models in their heads to work through any problem. In our world of storylining, there are many ways to collaborate to get to a better answer faster.

This week I was working with a group of product managers in a US technology company where collaboration was a key topic of discussion.

The group has loved the specific way we have encouraged them to collaborate to ‘land their messaging’ that kills three birds with one stone: it integrates into their natural working rhythm, lifts the quality of their messaging and saves them time.

These and others tell me that they no longer spend so much time chasing for responses, reworking their papers to present again and again to decision making bodies.

They also have much more valuable discussions with members of these bodies. They receive fewer clarification questions and more substantive ones.

We will take a break from our regular posts next week given the Christmas holiday season and will resume in the new year.

We wish you all a wonderful holiday season.


Warm regards,
