Chapter 5: Planning for Software Project Risks 121 Figure 5-4: The spiral model uses iterations to move the project to completion. Using the spiral model The spiral model is the safest, or most risk adverse, model available. An organization that uses the spiral model examines the project as a whole and then breaks down the project into subprojects, each of which are categorized by risks. The subprojects are then organized from risk heavy to risk lean. With the spiral model, you tackle the areas of the project where most of the toughest risks are first. This approach, which is frankly our favorite, hits the project risks head-on and then moves on to the next risk-laden subproject. We like this approach so much because there s nothing more frustrating than investing months in a project only to have it roadblocked by giant risks in month seven. With this approach, everyone knows whether the project can succeed right away based on the team s ability to plow through the hardest risks first. This model builds confidence and gains momentum. The logic is simple: If these are the toughest risks, then the project will only get easier from here. And it usually does. So why s it called a spiral model? Take a look at Figure 5-4; see how the project starts at the center and spirals out like a cinnamon roll? The completion of each subproject enables the project to move on to the next subproject until the project spirals all the way out to the release.
