As an example of the situation in Problem 17-6, Figure 17-23 shows risk categories at the program, subsystem, and functional levels. Starting at the bottom, data are developed for five engineering indicators and rated according to "high," "medium," or "low" risk. Results of this assessment are then summarized for each subsystem to provide a system overview. This is often considered a template risk analysis method. What are the advantages and disadvantages of this approach? Why is this method not used extensively today?

Problem 17-6
In the 1970s and 1980s, military organizations took the lead in developing ways to assess total program risk. One approach was to develop a rigorous process for identifying specific technical risk at the functional level and translating this detailed information through several steps. In this way, it was believed that risks could easily be monitored and corrected, as shown in Figure 17-22. Why is this method not being supported today?
