What could change in your workflow?

Reproduce the calculation

Calculation version: interpretation-capacity-v1. One workflow, one year, one currency. Costs, demand and capacities use matching annual units. Benefits cannot reuse the same saved hours. A negative case and an explicit zero cash-benefit check remain visible.

1. Net seconds saved/exam = gross seconds saved − additional rework seconds.
2. Annual capacity hours = eligible annual exams × net seconds saved/exam × adoption percent / 100 / 3600. Negative hours mean added workload.
3. Positive hours = max(0, capacity hours). Allocate all to the chosen cash path, or partition by the stated percent. Capacity-only hours have no cash value assigned.
4. Avoidable cash expense = target expense only when allocated cash hours ≥ required annual hours; otherwise 0. Reserved cash hours cannot also support extra exams.
5. Additional completed exams = floor(max(0, min(unmet annual demand, allocated exam hours × feasible exams/hour, available scanner slots, staffing/downstream capacity))).
6. Annual cash benefit = avoidable cash expense + additional completed exams × contribution margin/exam.
7. Annual net benefit = annual cash benefit − annual recurring supplier costs − annual additional operating costs.
8. First-year net = annual net benefit − one-time implementation/capital costs. First-year ROI percent = first-year net / complete first-year costs × 100, only if costs > 0.
9. Simple payback months = one-time costs / (positive annual net benefit / 12). It assumes steady annual cash flow, with no discounting, tax, financing or ramp-up model.
10. Zero cash-benefit check: first-year net = −(one-time + annual recurring + annual operating costs). It assumes no realized cash benefit, even if capacity improves.

This is a planning scenario. Assumptions require operations and purchasing review before decisions. The model does not rank products or replace clinical, IT, security or procurement diligence. Return to the evaluation pilot.
