What is the recommended action before making major changes to a project?

The recommended action before making major changes to a project is to save the project. This practice is crucial because saving the current state of the project allows you to preserve all your existing work, ensuring that you can revert to this safe version if any issues arise during the changes. By saving the project, you create a stable reference point that helps mitigate the risk of losing progress or having to redo work in the event that the major changes do not yield the expected results.

While documenting changes, notifying users, and compiling the project are all important steps in project management, they are typically secondary to the foundational action of saving your work to ensure the integrity of the project. Therefore, saving is the primary precaution that facilitates a smoother workflow when major alterations are planned.
