What is being changed at the constraint.
The part
What it is
Only the constraint is worth improving. Effort spent elsewhere makes the queue longer and the team busier, which is a worse outcome than doing nothing.
The cheapest fixes are usually standing decisions rather than more people: a pre-agreed boundary within which no approval is needed.

Kind
Fewer approvers, a clearer brief, a standing decision, or a separate route for low-risk work.
