An article in Forbes magazine asked 'What is the #1 problem every leader has and isn't aware of?' Author Mike Myatt poses that it is problem solving - plain and simple.
When most leaders are asked to self evaluate their problem solving skills, they judge themselves as great fixers. The question is, what do they measure themselves against? In Kraig Kramers CEO Toolkit, he lays out simple tools to help leaders measure their organization. 12 over 12 moving monthly averages and other tools help to measure progress, so that you spend more time looking for why something happened rather than what to do to fix the issue. As everyone says, you can't fix what you don't measure.
Ask yourself: What skills do you employ? They can be simple tools like Kramers, or they can be more esoteric tools. I have even taught recent workshops using Benjamin Franklin's Moral and Prudential Algebra. Anything that helps you to look at both sides, start to consider options and weigh potential actions against each other is all you need. And there are a wealth of resources for leaders if they choose to employ them. It really comes down to what works for the individual.
So begin to identify your toolkit for problem solving.
