Lean and shop floor practice.
9 pieces
Batching
Most of your changeover happens while the machine is stopped for no reason
Flow
Moving to pull does not remove the inventory. It shows you where it was.
Constraints
We added two people and nothing came out any faster
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
Batching
A batch size is a changeover time that nobody measured
Line balance
Takt time is a demand number, not a target
Constraints
Most constraints get elevated before they are ever exploited
Dana Okonkwo
Metrics, queueing and the maths posts.
9 pieces
Measurement
You have the cycle times. Now what does the picture mean?
Constraints
We fixed the bottleneck and the output barely moved
Queueing
How long will this backlog take to clear? There is an equation for that
Quality
A ten percent rework rate is not a ten percent problem
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
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
Tobias Lindqvist
Simulation, what if analysis and modeling method.
3 pieces
Rosa Delgado
Healthcare and service operations.
