Chapter 8: An end-to-end rule management... > 8.2. Analyzing rules - Pg. 228

8.2 Analyzing rules 207 5. When analyzing a process model, ask for each process the following: a. What are the events or situations (if any) that prevent that process from occurring? b. What are the events or situations (if any) that require that process to occur? c. What are the decisions (if any) that that process is required to enact? 6. When examining existing system specifications, program code, or DDL, you are of course looking out for the same obligations, prohibitions, and restricted permissions as with any other source of rules. 8.2 ANALYZING RULES There are three principal approaches to rule analysis: 1. one to be used when analyzing input forms or messages, or data models (the "data analysis" approach, discussed in Section 8.2.1); 2. one to be used when the source of rule intelligence is subject matter experts, potential system users, existing documented guidance, system specifications, program code, or DDL (the "raw rules" approach, discussed in Section 8.2.2); 3. one to be used when analyzing process models.
