13.4 Summary

CFA is a very useful tool. It can be applied to a wide range of activities, systems, and organizations to determine if the critical functions that are required for a mission to be successfully achieved or maintained are properly and adequately supported. It can also be applied to various phases of an activity, system, or organization to determine if the critical functions would be maintained under varying or adverse conditions. One of the difficulties with using the tool is getting all parties to agree as to what constitutes a critical function and what constitutes the components that support the critical functions. Also, terminology does vary between analysts who use the tool. As with all the tools and techniques discussed in this book, once the analysis is performed, the results can be used to improve the situation.
