Decision making process
Using a decision making process is very effective to avoid decision conclusion. Depending on past experience or intuitive judgement is not sufficient. People that does not follow a structured approach can end up focusing on aspects that are not part of the decision. The use of a decision process gives the decision maker a chance to focus on identifying the exact decision problem, identify the decision requirements or constraints and specifically identify the needed decision objectives.
This approach to decision process is very useful as it eliminates the possibility of deviation from the main decision problem. Moreover, this allows for selecting a decision tool that significantly contribute to the decision objectives. Furthermore, in the event of implementing a decision alternative that does not meet the requirements it is possible to track where things went wrong as everything should have been structured and documented.
When facing a system failure in an engineering asset, following a structured approach will focus the use of trouble shooting to develop decision problem, especially if the problem was reoccurring. Moreover, by identifying the decision requirements and objectives, as an engineer i can identify the machine constraints and needs. From there it would be possible to use fault tree analysis or QFD to go further to rectification.
