What this lane controls

Inputs

The variables you can actually control.

Outputs

The metrics that matter (yield, quality, consistency).

Cadence

How often you repeat the workflow without chaos.

Checks & balances

  • Contribution margin pays fixed costs — focus there.
  • Overhead must be allocated or it disappears.
  • Break-even is survival; profit starts after.
