FMEAs and FTAs were a challenging concept to grasp initially. The value of these analysis to the Design for Six Sigma process is priceless. However to effectively conduct and study these types of analysis it is important to completely understand and be experienced witht the process. It is hard to create and FMEA and an FTA when you don't know what the process is, how the process works. It is challenging to assess the possible failures and effects if one is not familiar or has experienced the process beign discussed.
I think this was one of the problems we had in our group. Our lack of knowledge about the tank exercise caused us to struggle a little with creating a fault tree analyses. It was especially difficult with the fault tree analyses because you must realyy comprehend the process in order to accurately determine if some steps in the process are independent or dependent on other steps to illustrate OR gate or an AND gate. I think these types of analyses is useful to people that have experience with the subject at hand and can be a very useful too.
