Planning. The staff answerable for the change creates a detailed plan for its design and implementation, as well as for rolling back the change ought to it be deemed unsuccessful.
Designing and testing. The crew designs the program for the software change and tests it. If the change is deemed profitable, the crew requests approval and an implementation date.

procurement of supplies, labor, skills and different necessary project resources; and
stakeholders -- including project managers, executives, firm owners, workforce members or investors -- who could voice their help or push back on a project.
