In this chapter, we determined the project requirements to actually make a fuel transfer simulation. With this information, we wrote the code to create the component instances and the system functionality. This allowed us to show the fuel flow from the storage tanks to the pump outlets via different valve lineups. Finally, we talked about testing the simulation and how a single fix to one error can actually fix a variety of issues at once.

In the next chapter, we will look at a software project post-production. We will specifically look at how to document code with docstrings, how to generate user-friendly documentation, and how to review lessons that we will have learned from this project.
