Problem-solving

Decision-making is essentially problem-solving.
Even though it can be lengthy and time consuming, I tend to engage in (upfront) systematic diagnostic processes through intense investigation.
A structured approach that rules out obvious, easy answers.
I recommend the use of decision/logic trees. It offers a useful way of breaking down a problem into consequences and options.
The 7-steps process, develoed by two ex McKinsey (see diagram) is very effective.
The story telling helps with the ‘show & tell’ of the results. People can track the process and follow the conclusions.
