Diagramming Techniques

Three types of diagramming techniques are used in Identify Risks: cause-and-effect, system or process flowcharts, and influence diagrams. Cause-and-effect diagrams show the relationship between the effects of problems and their causes. This diagram depicts every potential cause and subcause of a problem and the effect that each proposed solution will have on the problem. This diagram is also called a fishbone diagram or Ishikawa diagram after its developer, Kaoru Ishikawa. Figure 6.2 shows an example cause-and-effect diagram.

The system or process flowchart shows the logical steps needed to accomplish an objective, how the elements of a system relate to each other, and what actions cause what responses. This flowchart is probably the one with which you're most familiar. It's usually constructed with rectangles and parallelograms that step through a logical sequence and allow for "yes" and "no" branches (or some similar type of decision). Figure 6.3 shows a flowchart to help determine whether risk response plans should be developed for the risk (I'll talk about response plans in the section "Developing a Risk Response Plan" later in this chapter).
