The model presented on the previous page begs the question, where do you start? What do you do first? The project could start as a result of feedback after the learning experience was executed.
However, if a version of the product doesn't exist, you start with an idea of what you want or need. With research and analysis, more detail is added. The details reveal issues, challenges, and options that might not be known when the project starts. These new findings can be discovered and addressed in all phases of development. However, unless the product is not operable, the implementation phase is typically not the time to make changes.
