Typical Payback

Establish your production baseline

Before you model savings, anchor the math in what you produce today. These inputs feed every downstream calculation.

For: Operations Managers & Plant Engineers

Annual Output (units)

e.g., 2,400,000 parts produced

Average Unit Cost (CHF)

e.g., 4.20 fully-loaded cost

Current Scrap Rate (%)

e.g., 2.8% of units rejected

Customer Returns Rate (%)

e.g., 0.6% field defects

Shifts per Day / Days per Year

e.g., 3 shifts × 250 days

Production Line Count

e.g., 4 inspection-eligible lines

Model scrap and rework reduction

Computer vision catches defects earlier in the process, before added value is wasted. Quantify both the units saved and the downstream cost avoidance.

For: Quality Leads & CFO Stakeholders

✓Detection lift: Estimate the share of current escapes that vision would flag — typically 60–85% in stable processes.

✓Early-stage catch rate: Define the percentage of defects intercepted before the next value-add step (assembly, paint, packaging).

✓Rework cost per unit: Capture average labor + materials to recover a defective part vs. scrapping it outright.

✓Warranty & return avoidance: Multiply field defect rate × average claim cost × annual volume.

✓Throughput recovery: Convert eliminated scrap into recovered saleable units at your gross margin.

Reallocate inspection labor

The goal isn't headcount reduction — it's freeing skilled operators from repetitive visual checks so they can focus on root-cause work and process improvement.

For: HR Partners & Line Supervisors

Step 1 — Count current inspection FTE

Sum manual QC hours per shift across all eligible stations, then divide by your standard FTE-year.

Step 2 — Define automation coverage

Identify which stations vision will handle end-to-end vs. augment with operator confirmation.

Step 3 — Reassign to higher-value tasks

Model the redirected hours toward process tuning, supplier audits, or continuous improvement projects.

Step 4 — Capture fatigue & consistency gains

Account for the elimination of end-of-shift accuracy drop-off, typically 8–15% on visual tasks.

Size the investment honestly

A defensible ROI model includes the full cost stack — not just cameras. Use these line items to build a credible total cost of ownership.

For: Project Sponsors & Procurement

Hardware (cameras, lighting, edge compute)

e.g., CHF 28,000 per inspection station

Software & model licensing

e.g., CHF 12,000 / line / year

Integration & mechanical fixturing

e.g., CHF 18,000 one-time per line

Training data collection & labeling

e.g., 4–6 weeks production sampling

Internal team time (PM, IT, OT)

e.g., 0.5 FTE for 4 months

Ongoing maintenance & retraining

e.g., 12% of CapEx / year

Calculate payback and sensitivity

A single ROI number rarely survives a steering committee. Present a range — and show which inputs move the needle most.

For: Finance Reviewers & Executive Sponsors

✓Annual gross savings: Sum scrap avoidance, rework reduction, warranty avoidance, and reallocated labor value.

✓Net annual benefit: Subtract recurring software, maintenance, and model-retraining costs.

✓Simple payback (months): Total CapEx ÷ (Net annual benefit ÷ 12).

✓3-year NPV: Discount net cash flows at your internal hurdle rate — usually 8–12%.

✓Sensitivity scenarios: Run conservative, base, and stretch cases against detection lift and unit volume.

✓Breakeven scrap rate: Identify the minimum defect rate at which the project still clears your hurdle.

Pro Tip

The single biggest mistake in CV business cases is overstating detection accuracy in year one. Model 70% of vendor-claimed performance for the first 6 months — and budget for one round of model retraining once you've seen production conditions. Steering committees reward conservatism backed by real data.
