There is always an emphasis on the importance of collecting as much information as possible to make a robust decision. however, what happens if there are too much information that make it confusing to make a decision?
many would argue that among this information there is useful and relevant information and irrelevant information that must be excluded from the decision making. this argument leads to another decision to be made, that is decide which is the useful information. the complexity here is obvious especially for complex situation.
other argue that the best solution to avoid such dilemma is to ask very focused questions that require limited information to answer them. this would help in avoiding the huge amount of information and in categorise them to relevant and irrelevant.
The above is ideal and is relative depending on the uniqueness of every situation. however, it worth thinking of especially in the reality of the increasing information that is result of the technology development and establishing knowledge management systems.
