This page explains exactly how we calculate return, what we are prepared to put at risk, and the assumptions we refuse to include even when they would flatter the case. It is deliberately more conservative than the numbers you will see elsewhere in our industry.

Target payback period on every engagement

Counted in the payback calculation
Business cases in technology are usually inflated by three habits: counting benefits that cannot be traced to a ledger, assuming that everything works at once, and ignoring the internal cost of the client's own people. We remove all three, which produces a smaller number that survives contact with a chief financial officer. The adoption factor is the input most vendors omit entirely — a system used by 60% of intended users returns roughly 60% of its modelled benefit, which is why adoption is a design deliverable rather than a training afterthought.
Everything on the left can be traced to a ledger, a timesheet or a system log. Everything on the right may well be real, and we still keep it out of the payback calculation.
Soft benefits appear in our proposals as commentary, never as arithmetic. If the payback only works when morale is monetised, the payback does not work.

Defined deliverables, fixed fee, agreed change process. Appropriate where the outcome depends heavily on decisions outside our control.
A defined portion of our fee depends on the agreed metric moving. Requires a clean baseline and a metric we can both trust.

Three details matter more than the result. First, the adoption factor of 0.7 reduced the modelled benefit by nearly a third before we quoted anything. Second, the client's own internal cost is included in the investment line, because their people's time is not free. Third, the historical conversion rate came from their records, not our optimism.
The actual outcome after twelve months exceeded the model, largely because response speed improved conversion on calls that were previously answered too. We did not include that in the forecast, because we could not defend it in advance.
Payback period in the business case
Payback achieved after deployment
Every engagement targets payback inside a year. Where a longer horizon is genuinely justified — platform work, regulatory programmes — we state it plainly rather than manufacturing near-term benefit to hit a number.
We model using your cost of capital and your finance team's conventions. A business case that only works under favourable assumptions is a sales document, not an investment analysis.
About one assessment in five concludes that the return does not justify the work. We write that down and send it. It is the only credible way to be trusted on the other four.

Where the return does not justify the work
The value assessment produces a payback model using your baselines, your conversion rates and your cost of capital. You keep it regardless of what you decide.
