The rigor imperative
When the project is emotional, or urgent, or loaded with resonance, it's easy to dispense with rigor. It is, after all, an emergency. No time for the process, for doing the hard part first, seeking best practices, or reverse engineering toward the desired result…
Of course, the opposite is true. If it's worth getting into a swizzle about, it's worth doing properly.
Do the math, do the reading, do the budget. Do it right.
