A lot of our triumph, as a species and in our organisations, is courtesy our superior thinking. If we can break a problem – whether in our jobs or in our lives – and think through it systematically, we can also come out with stellar solutions.
Unfortunately, while “thinking is the ultimate human resource” it is often done so poorly across organizations. Often, we don’t understand the real problem, or attack only one aspect of it, or lack creative ideas or let our biases take hold of the process. “The main difficulty of thinking is confusion. We try to do too much at once. Emotions, information, logic, hope and creativity all crowd in on us.”
Dr Bono invented the concept of lateral thinking and teaches thinking as a skill. He has taught in the universities of Harvard, Oxford and Cambridge and is hailed as one of 250 people who have contributed most to mankind.
This multi-million copy bestselling book, Six Thinking Hats, shows a process to conduct thinking much like a conductor conducts an orchestra. In traditional thinking, if two people disagree, there is an argument in which each tries to prove the other party wrong. This book promotes parallel thinking in which both views, no matter how contradictory, are put down in parallel.
The idea is that while solving for a difficult problem we ask the team to systematically wear different ‘hats’, and each participant, at one time, thinks only in that direction:
The meeting chairperson can say,
“Let’s switch to yellow hat and see how big can this initiative be. Please think two minutes on your own and then each participant will speak for exactly one minute on yellow hat only.”
Or, “I am not yet satisfied with the alternatives we have so far. Let’s put ur Green Hat and we will go around the room.”
Or towards the end of a meeting, “Are we happy with the outcome, did we do a good job? Let’s everyone wear the Red Hat and describe their feelings in maximum 5 words”.
We also need to be cautious against the overuse of a hat. For example, black hat thinking is important but overuse can make people get comfortable in criticizing instead of contributing. An idea which is 80% good and 20% imperfect can be criticized (and all focus going on the 20%) in the design phase because we can still correct the 20%. But in the final assessment phase, the excellent 80% should be acknowledged.
In companies as varied as ABB, NASA, Shell, IBM, Dupont, NTT, this has resulted in 75% reduction in meeting time (less wasteful to and fro) and 5 times increase in productive ideas (the intelligence, knowledge and experience of each team member is put to full use). It also leaves much lesser ego bruises and fosters better cooperation.
I have often used this in my meetings and can vouch for the results. With 20 people in a project, there is always a fear that someone’s views are not heard or someone’s views get dominating. Or we may have missed a risk or missed an opportunity. So, we can ask everyone, “let’s have a round of red Hat”, where everyone just describes their feelings (without any justification). Or just before agreeing on a project, ask everyone to give one Black Hat idea (what could go wrong).
Depending on the situation, you could do only one hat, or few or all hats or repeat hats. The important criteria are Discipline (when one hat is being discussed, even opponents need to think in the same direction); Time management (put idea succinctly and move on, generally one minute per participant per hat); and Process (when will which hat be used).
The book has few chapters on how to use each hat and the challenges therein, but often gets repetitive. I do think this could have been a great HBR kind of article instead of a full volume book.
Why you should read this book: To learn a new and solid method of thinking in groups. Practise this in your own teams and classes and be amazed by the results. The biggest enemy of thinking is complexity, for that leads to confusion. Six Thinking Hats makes thinking simple, more organised and hence more effective and enjoyable.
