The Hows and Whys of Software Development (Writing a SDLC)

TLDR: Click to Download my Software Development Life Cycle Document

What is your policy on the use of production data for development?

How does someone go about creating a new feature?

What do you do when you encounter a bug in your software?

How do you protect against common coding vulnerabilities and ensure best practices?

Do you have this all documented!?

You would likely be able to field most of these questions if asked to. The bigger question that I was faced with recently was the last question on the list... IS IT DOCUMENTED.

Once a company grows beyond a certain size, having these procedures documented and available becomes a necessity. These types of documents will often times be used for onboarding new developers or provided to a potential client that has regulations to worry about when choosing their development team. The problem I faced when trying to document these processes was that I could not find any good examples to start from. WHICH IS WHY I am now releasing a modified version of what I created as a starting point for you.
