What-If and Scope

What-If Step 2

Improving the bottleneck step changes the exact line capacity and slack.

highlighted = computed this step

Improve Step 2

The second step improves to 24 units per hour.

New Capacity

The recomputed line capacity is 24 units per hour.

min⁡(what-if step rates)=24\min(\text{what-if step rates}) = 24

New Slack

With demand still 18, slack rises to 6 units per hour.
