On the floor first
I work your process before I change it.
For New Zealand Business Owners. We find the one thing capping output and fix that first. You keep the method.
A business is a chain. Output is set by the weakest link, not by how hard everyone else works. Most shops try to speed up every station. The piles move. The due dates do not.
I follow one real job from enquiry to cash. I stand at the pile. I watch the process fail the way I would watch a machine fail. Only then do we change anything, and we change the constraint first.
The order
Walk the job
One order, enquiry to cash. Mark every wait.
Name the weak link
Machine, person, rule, or market. In your words.
Read the money
Throughput, investment, operating expense.
Delete before you spend
Squeeze it. Then spend only if you still must.
