You sequence tomorrow's runs by batch size and delivery order.
Whether that sequence costs 3 hours or 9 hours in changeovers, you won't know until you're in it.
Changeover time matrix
Every product switch has a cost. Now you can see it before you commit.
Every line has fast product switches and expensive ones. Most plants don't know which is which until the clock is running. The choice gets made on instinct, by batch size, by whoever is in the room. The cost shows up in OEE.
Three scheduling decisions made without the data
Each one traces back to the same gap: no view of changeover cost before the commitment is made.
REF-31D to REF-55E starts. The line stops.
Three hours in, you realise this is the worst pair on the line. The schedule can't move.
You learn which pairs are expensive over months of runs.
Nobody records it. The same sequence gets scheduled again next week.
The cost of a bad sequence is real. It just isn't visible until after you've committed to it.
The changeover time matrix: every product pair, ranked before you run any of them.
ProChangeover computes planned changeover time for every product pair on your line using your actual task structure. One view. Every combination. Colour-coded from green (cheapest) to red (most expensive). Products grouped by category so the structure of your line is immediately visible.
The matrix is built from your task structure, not entered manually. Add a task, change a planned duration, restructure a changeover — it recalculates automatically for all affected pairs. Open it directly from the line screen. No separate planning tool. No version drift.
The data was always in your task structure. Now it's in one place you can use before you commit.
Three things the matrix tells you at a glance
You don't need to read every cell. Three observations are enough to sequence better.
01
Pick the cheapest landing spot before the schedule locks
The greenest column is the product your line arrives at cheapest from anywhere. End a long run there — or start the day with it — and every transition in the sequence costs less.
02
Know which pairs to avoid before they're committed
The reddest row is the product your line leaves most expensively. Spot it before the schedule is built, not after the clock starts. Move it to the end of the sequence or avoid back-to-back placement.
03
Always have a cheaper next move ready
For any product currently running, the row shows every option and its cost. When a batch finishes early and the schedule has flex, the matrix tells you the cheapest thing to run next.
4 hours 48 minutes saved. Same products. Different order.
The sequence below runs the same five products. The only variable is the order — chosen by batch size versus chosen by the changeover time matrix.

Who uses the changeover time matrix
Production planner
See which sequence costs least before committing the day's schedule. Adjust the run order in 30 seconds if a cheaper path exists.
Process engineer
Spot the expensive pairs and focus standardisation effort there. A 20-minute reduction on a red cell pays back across every run that pair appears in.
Shift supervisor
Verify the day's run order against the matrix before the first changeover starts. Catch a bad sequence while there's still time to change it.
