Another tip for decision making, create a list of pros and cons. This applies to both the people who make a decision and those who wait for a decision to be made.
When I need a decision to be made, I always offer options as well as a list of the pros and the cons to my supervisors. The conversation is normally like the following – we need to make this decision. We have a few options 1, 2, and 3. The pros and the cons of each option area xxxxx. What do you think?
In the above scenario, I was often asked about my opinion. I offer my thoughts. I prefer option 2 because xxx. And, if worse comes to worst, we can do yyy.
Sometimes, you have to be kind to those who have to make a call. He or she might not be close to the situation like you are. You have to be fair by offering all information you have. It works for me most of the time.
