A workflow for handling multiple concurrent changes on a single software system

To me, a change will mean that I am going to have more rice on my bowl. And in my nature of work, changes to the software systems under my care occur pretty often.

Nearing project completion, I volunteered to engineer a new workflow for my company to handle software development after we took over the system from the software development house. The main objective of the workflow is for coordinating change deliveries from multiple development teams on a single software system suite.

This post documents the workflow that I had engineered.
