Scrum Model Scrum assumes that the software development process is complicated and unpredictable and treats it as a controlled black box instead of a theoretical, fully-defined process. This is one of the biggest differences between Scrum and the Waterfall and Spiral methodologies, which view the software development process as a fully defined process. Most problems encountered when using these older, formal types of methodologies are: --- Requirements are not fully understood at the beginning of the process. --- Requirements change during the process. --- The process becomes unpredictable when new tools and technologies are used. Another characteristic of Scrum is that the software development process isn’t treated as a linear process, unlike the Waterfall, Spiral and Iterative methodologies. In a lot of cases this linear process consists of the following four activities: Analysis, Design, Implementation and Testing. Scrum, however, doesn't prescribe a sequence in which the activities must be implemented. A project can start with any activity, and can change between activities at any time. This increases the project's flexibility and productivity. To manage these processes with flexibility, Scrum supplies techniques and controls to manage this unpredictable process.
