Decision making tools, always useful or not?

Writing about web page Robust Decision making

A reflection of last week, it was great working with the team, as they were no arguments whatsoever! Everyone was really cooperative and we were well prepared.

Choosing which decision tools was a difficult task, as we had to first understand how the tool would help us analyzing the problem question and then coming up with the decision. Each tool had its own advantages and disadvantages. Some tools were just really straight forward like SWOT. Others were a bit more complicated like SMART and the decision tree.

One thing that I noticed while working in the group was how the decision makers influence the decision. When using tools such as SMART and AHP, the decision makers have to give the weights to the most favorable and the least favorable characteristics. They base their decision on research, but their gut feelings also have a role to play in the decision tools. This may lead to biased results.

My team had divided the work in such a way that each of us was responsible for using one decision tool. Some of us were unable to do it as group thinking was required for assigning weights. This led us to work as a group and apply the decision tools to the given situation. Since a lot of information was not available to us, we were forced to base our decisions on assumptions leading us to come up with the final decision we intended on. I say this because there was one team that justified through the decision tools that they chose Exmouth, whereas none of the tools that we used gave us that result. I wonder how they came up with calculations that supported their claim when there were four groups who decided to go ahead with Lymington.

As discussed today in class how everyone had a different decision tree. The reason for this was that everyone's mind works differently and each problem is solved with a different approach even if the decision tool is the same. So I guess there is no right or wrong decision tool. The decision depends on the decision maker. This is what I think after going through the robust decision making module..

Would look forward to hearing what you all think!!
