Enterprise AI ROI assessment: periods, benefit units and complete costs

Start enterprise AI ROI assessment with the work to improve, its comparison baseline and an owner who can confirm benefit. Establish quality, permissions and acceptance before estimating accepted work volume and full cost.

Put the horizon, currency, price dates and one-time/recurring expenses in one model. Compare aligned scopes rather than one option's first-year implementation against another's monthly licence.

Separate hours, capacity value and financial benefit

For eligible tasks, measure human work, review, correction and handoff in baseline and proposed flows. With aligned units:

Released hours = accepted completed tasks in the period × (baseline human hours per task − new human hours per task)

Convert time to consistent hours; the difference may be negative. If volume already measures used, completed tasks, do not multiply adoption again. For forecasts from all eligible work, document use and completion assumptions separately.

Capacity value = released hours × agreed hourly work cost

This values capacity rather than establishing staff removal or lower spending. The UK Government Efficiency Framework distinguishes spending reductions from monetizable non-cash productivity. Borrow that distinction as a method, not a Taiwan corporate accounting rule.

Finance owners confirm realized spending reductions, attributable incremental profit and other admissible benefits. Revenue is not profit. Risk effects need event, probability, loss and comparison evidence; reviewing documents does not justify crediting a whole recall. Keep capacity and cash accounts separate to avoid overlap.

Define the ROI measure

For a total-cost denominator over one horizon:

Period ROI = (compatible monetary benefits B − total period costs C) / C × 100%, C > 0

B and C need consistent periods, currency and valuation basis. Hours cannot be added directly to money. Identify non-cash valuations if included and report cash results separately.

Include implementation, data, interfaces, licences, internal coordination, evaluation, training, model/tool use, review, maintenance and exit. Count one-time and recurring costs once. Explain annualization or allocation rules rather than comparing unlike models.

The GAO cost guide supports scope, assumptions, data, sensitivity and updates with actual costs. It is not a supplier price table. Replace unsupported percentages with pending project-specific estimates.

Industry tasks are candidates, not payback rankings

Assess each candidate through its actual baseline, volume and costs rather than predicting fastest payback from the industry. Models, data, integration and use can all affect results.

Update evidence and model cash timing separately

Record assumptions, versions, ranges and stop conditions. After a pilot, update accepted volume, quality, full cost and benefit. Compare scenarios for influential inputs rather than presenting one estimate as a commitment.

Payback needs period-by-period cash outlays and cash benefits: when cumulative net cash offsets investment differs from an annual ROI percentage. Finance reviews timing, allocation and overlap before deciding to continue, prepare further or stop.

The existing work-time value calculator offers adjustable gross-capacity scenarios, excluding model/API, operating and human-review costs. It does not calculate net ROI or payback. See engagement to establish scope, responsibility and quotation assumptions.
