FMEA and FTA

For the tuesday class, we learnt about Failure Modes Effects and Analysis (FMEA). it is an useful tool that help to evaluate potential failures of products or service that might occur. It also helps to illustrates causes, effects, and improved actions. In my opinion, I think it is better for an organization, especially in design department, to use the FMEA tool before launching products or service, and during testing it. This is because FMEA analysis is kind of a forcast tool for the department to plan for the solution for problems that might occur toward products or service. If the department previously concern on doing this, it will help to reduce possibility of failure occurance. In the serving tea excercise, I was really enjoyed. In my group, we tried to come up with the worst scenario, we helped each other thought of the possible failure that might occur.

During the afternoon session, Jane talked about Fault Tree Analysis (FTA). In my view, I thought this one is more difficult to understand comparing with FMEA due to in the FMEA tool, it tells us what we have to do, what we need to find and what we need to concern (such as potential failure, potential effects, potential causes, severity levels, and recommended actions. However, FTA is not provided any standard table for us to do. It encourages us to draw a tree chart from our understanding. Honestly, during the excercise about engine and leak pipe, I was very confused and it was hard to complete the chart. But I think if I could understand in engineering terms, I believe I could complete it. Also, I think it is also as useful as FMEA due to it could provide the potential failures and effects.
