Processes are meant to be tweaked.
To overhaul them, to have the suggestion that they need to be overhauled by one person on their team means one of two things;
- They don’t understand the process (and thereby think it needs to change)
- They understand the process (and thereby know it needs to change)
You only overhaul once, after that, it’s tweaking on tweaks to keep improving it and making it better.
If you’re overhauling your process all the time, you aren’t in the business of whatever it was you were in before, you’re in the business of building processes (which very few set out to do).
