Ask where the value goes
When a task becomes faster, the first result is potential capacity. Whether that becomes business value depends on demand, how work is organised and whether quality remains acceptable. A team may use the time to serve more customers, reduce a backlog or improve work. It may also struggle to make small fragments of saved time useful.
A business case should say which of those outcomes is expected and what would demonstrate it. Avoid describing every saved minute as a cash saving.
Include the costs outside the subscription
List setup, integration, training, human review, corrections, ongoing monitoring and switching costs where applicable. Allocate shared costs transparently rather than assuming they disappear. Include the time spent supervising the system when calculating the workflow result.
Compare costs over the same period and use actual task volumes where available. Keep one-off implementation costs distinct from recurring costs so decision-makers can see the difference.
Use an explicit illustrative scenario
Suppose a workflow saves 10 net minutes on each of 40 monthly tasks. At an assumed £30 per hour, the gross capacity value is £200 per month. If incremental tools and amortised setup cost £80 per month, the model leaves £120 before other costs and uncertainty.
This is an illustrative calculation, not a Vertex study or a forecast. It assumes the time can be put to productive use, review is included, output quality is acceptable and task volume remains stable. Change those assumptions before applying it to a real business.
Keep adoption statistics in context
Adoption figures describe the use of a technology under the definitions of a survey. They do not establish the return on a particular workflow. ONS publishes evidence on AI use in UK businesses, which is useful context for a research question, but it does not replace a local baseline and evaluation.
Similarly, a vendor case study can help generate hypotheses while leaving selection, measurement and transferability questions unresolved. Examine how the result was produced before reusing its headline.
Write a decision-ready business case
Present the task, baseline, quality threshold, observed changes, direct costs and assumptions. Add a sensitivity check: what happens if task volume halves, review time doubles or subscription costs rise? Identify the conditions under which the investment would no longer be worthwhile.
End with a practical action: continue under monitoring, run another evaluation, change the workflow or stop. The quality of the business case lies in the clarity of the decision and its evidence.
