Software development with performance focus
Let's first revisit the major steps of the software development process in more detail with a healthy focus on performance and some quality. Remember that these steps are run iteratively, with possible shortcuts, and sometimes, with very short iterations!
Some organizations may also define the process a bit differently, with some steps included in other processes such as the requirement and QA processes. The following diagram shows us a common version of the software development process from which we will discuss its different phases. We will, however, not talk about the acceptance testing and deployment phases in the process, as they normally won't have any direct impact on performance tuning.
