Using Development Methodologies

In this chapter, we explore various development methodologies used on projects either alone or in conjunction with a bigger project framework. Most project work can be a chaotic activity, often characterized by the phrase "fighting fires." The project is often started without much of an underlying plan, and the designs are often changed because of technology or error. Sometimes the project is simply cobbled together from multiple quick-paced decisions. This can be effective if the project is small, but as the project grows to be a medium- or super-sized project, it becomes increasingly difficult to add features to the system. The project manager's coordination skills are tested to the fullest extent as the project gets larger. Furthermore, mistakes become increasingly prevalent and difficult to fix (i.e., change control, issue logs). For example, building a space vessel begins with a blueprint based on numerous aeronautical and mathematical calculations, including material specifications, variables, and tolerances. Any change to this blueprint, which must be followed at all times, can kill the project because changes are costly and schedules can be horribly affected. The tools and materials that were manufactured specifically for the space vessel project are very expensive and should not change during the construction phase. On such a project, everything needs to be predictable.

Alternatively, when we look at developing software, we see something very different. We obviously try to build new software solutions usually with new technologies therefore, the associated risks are very high. In comparison to building space vessels, developing software is not the same. One is predictable and the other is not. In this chapter, we look at predictable methodologies, then at nonpredictable ones.
