Constraints
We fixed the bottleneck and the output barely moved
Batching
Most of your changeover happens while the machine is stopped for no reason
Measurement
We have no data. Where do we start?
Flow
Moving to pull does not remove the inventory. It shows you where it was.
Queueing
How long will this backlog take to clear? There is an equation for that
Process mapping
Ninety seven percent of that form's life is waiting
Variation
Your step does not take eight minutes. It takes a shape.
Scheduling
Monday looks worse because Friday never finished
Root cause
The five whys finds one cause, and most delays do not have one
Constraints
We added two people and nothing came out any faster
Quality
A ten percent rework rate is not a ten percent problem
Process mapping
The boxes on a process map are not where the time goes
Standard work
You cannot automate a step that is done five different ways
August 2026
Variation
The average was met and a quarter of the orders were late
Bottlenecks
The hour you lost at the bottleneck did not cost forty five dollars
Batching
A batch size is a changeover time that nobody measured
Utilization
The last ten percent of utilization costs more than the first eighty
Queueing
Little's Law does not care what the board says
Measurement
Cycle time and lead time are not the same number
Line balance
Takt time is a demand number, not a target
Constraints
Most constraints get elevated before they are ever exploited
