What-If and Scope

Step B What-If

Changing one step yield recomputes the full serial product.

highlighted = computed this step

Step B What-If Yield

The what-if step B yield is 9/10.

what-if yield B=9/10\text{what-if yield B} = 9/10

What-If RTY

The what-if RTY is 27/40.

what-if RTY=27/40\text{what-if RTY} = 27/40

Final Good Gain

The final good-unit gain is 15 units.
