CHAPTER 6  RISK ANALYSIS AND MANAGEMENT                            151

                              a characterization of the potential consequences of errors (rows labeled 1) or a failure
                              to achieve a desired outcome (rows labeled 2) are described. The impact category is
                              chosen based on the characterization that best fits the description in the table.


                        6.4   RISK PROJECTION

                              Risk projection, also called risk estimation, attempts to rate each risk in two ways—the
                              likelihood or probability that the risk is real and the consequences of the problems asso-
                              ciated with the risk, should it occur. The project planner, along with other managers
                              and technical staff, performs four risk projection activities: (1) establish a scale that
                              reflects the perceived likelihood of a risk, (2) delineate the consequences of the risk, (3)
                              estimate the impact of the risk on the project and the product, and (4) note the overall
                              accuracy of the risk projection so that there will be no misunderstandings.

                              6.4.1  Developing a Risk Table
                              A risk table provides a project manager with a simple technique for risk projection. 2
                              A sample risk table is illustrated in Figure 6.2.
