Conclusion

Over the years, engineering disciplines have used a variety of techniques to improve products and product reliability. A couple of the commonly used techniques in industries such as aerospace and transportation are failure modes and effects analysis (FMEA) and fault tree analysis (FTA). These techniques are used to proactively determine potential product failure modes and the causes of unintended events. The purpose is to identify potential defects early in the product development process so that they can be eliminated or mitigated during product design.

These same techniques can also be used in software development to help prevent software defects. As in other applications, the goal is to identify potential defects proactively so ...
