RDM–In Module Reflection

During the past two weeks group work to make team decisions, I learned group decision making process is sometimes easier but also more difficult. It’s earlier to see the circumstances thoroughly when team members have their own perspectives, but it’s also more difficult to incorporate everyone’s opinions to come up conclusions that everyone agreed. What we decided to do was to use various tools, came up with the suitable tools for every question and supported every decision we made.

We tried total 10 tools-SWOT, Decision Tree, AHP, PARETO, Risk Analysis, Grid Analysis, SMART, Soft system, Scenario Analysis, and PMI, after discussion, we decided every tool for each question.

Question 1-to continue or not producing the new product.

Tool-Risk Analysis. We conducted PESTLE-political, economic, social, technological, legal and environment to anticipate all external factors and came up with decisions.


Question 2-Which location to choose.

Tool-PMI. We summed up all scores of the plus, minus and implications to get our decisions.


Question 3-Is an advertisement campaign is essential or not.

Tool-Scenario Analysis. We predicted importance and uncertainty to come up with scenarios and made decisions.


Finally, we used Decision Trees analysis to justifying all the decisions we made. Decision trees are a graphical representation of a decision, each tree has arms which represent the choices and a value associated with it. It clearly depicts all possibilities and values for us to choose and it provides a holistic view.

As Jeff said during class today, we can’t avoid bias completely which means there is no 100% objective decisions existing, tool itself may be scientific and objective but we can’t avoid our personal preference and judgement when we are using it, since we have different backgrounds, beliefs, emotions, cultures and values…etc that will led us to different points of view. Therefore, I think the most important thing is that we listen to others opinions to examine if there is any aspect we ignore, choose suitable tools based on information available, timescale, decision complexity, participant numbers in decision, factors in the decisions, and test various tools to come up with the most rational and logical conclusion to support our decisions.
