Process / Philosophy
Four moves
every time
No frameworks for the sake of frameworks. Just the sequence that keeps working.
SEE THE PROBLEM.
Sit inside the workflow before changing it. Talk to the people doing the work, read the tickets, follow the order.
FIX WHAT MATTERS.
Prioritize the few breakpoints causing most of the cost, churn and chaos. Ignore the vanity work.
BUILD IT TO LAST.
Document it, train it, automate the repeatable parts. A fix that needs a hero every week isn't a fix.
MAKE AN EFFECT.
Measure the change in real terms: faster resolutions, cleaner inventory, better launches, calmer teams.
