What-If and Scope

B Demand What-If

A single demand change can use up the remaining slack.

highlighted = computed this step

B Demand What-If

The what-if raises product B demand to 30 units.

what-if B demand=30\text{what-if B demand} = 30

What-If Load

The recomputed total load is 150 minutes.

60+90=15060 + 90 = 150

What-If Slack

Utilization becomes 1 and slack becomes 0.
