Why Don’t You Practice Test First Development?

I would have said “Test Driven Development” but I want to make it clear that what I’m talking about is writing test first, or at least simultaneous to writing the code. Not sometime after, even if that after is immediately after.

Most requests can be satisfied but developers have a tendency to rebut with "no" when they believe the work is too difficult, requires extensive time, or for a variety of other concerns.

Likewise, the DevOps organization is a somewhat more likeable term, but still ambiguous at best.
