Sometimes patching a process is not enough. We document it as it really runs, find where it stalls, then draw a simpler new version and trial it before wider rollout.
And hard to trace.
And no documentation.
When it should be simplified first.
Clear maps for each one.
Causes of delay and error.
With roles and authorities.
Current and target.
Written clearly.
And training.
And the study boundary.
Step by step.
And present it.
And follow up.
