ROI & the business case: prove the value honestly

Your CFO peers are asking the same question you are: is any of this AI spend actually paying off? This session gives you an honest way to measure value - time, cycle-time, error reduction, and capacity you redeploy - and a one-page business case you can put in front of a finance committee without overclaiming. We will also look squarely at why so many pilots show no P&L impact, so yours is not one of them.

Why this session exists

You have picked use-cases (a2), set the guardrails (a3), and thought about the team (a4). Now comes the question that unlocks budget or kills it: what is the return, and can you defend the number? The uncomfortable truth is that most AI value is claimed loosely and measured badly - which is exactly why finance leaders, of all people, should hold it to a higher standard. This session hands you an honest scorecard and a one-page business case, so your bet is credible in the room where money is decided.

Measuring value honestly 6 min live

There are real value levers, and there is theatre. The real levers are measurable and modest at first; the theatre is a headcount-reduction slide that never survives contact with reality. As a finance leader your credibility rests on counting only what you can defend, so let us name the levers that hold up.

AI investment licenses · setup · training time Time saved hours off recurring tasks Cycle-time cut e.g. close days reduced Error / rework down fewer restatements, catches Capacity redeployed same team, higher-value work Net value measured, defensible, not theatrical Count capacity you redeploy - not headcount you promise to cut and never do.

LiveThe value levers that actually hold up3 min▶

Every credible AI return in finance traces back to one of a small set of levers. Learn to name them, and you can measure any use-case honestly.

  • Time saved. Hours pulled out of recurring, low-judgement work - reconciliations, first-draft commentary, data cleanup. Count it as hours, then convert to cost cautiously.
  • Cycle-time. How much faster something finishes - a close cut from ten days to eight, a board pack drafted in a morning not a week. Speed has real value even when hours are flat.
  • Error and rework reduction. Fewer restatements, fewer missed accruals, more anomalies caught before they matter. Quality is money you never lose.
  • Capacity redeployed. The honest version of "efficiency": the same people spend freed hours on analysis, business partnering, and judgement. This is the lever that survives scrutiny - a promise to cut heads usually does not.
The baseline rule You cannot measure a saving you never sized. Record the "before" - close days, hours per report, error rate - before the pilot starts. No baseline, no credible ROI. This one discipline separates real cases from wishful ones.
LiveThe counterweight - why most pilots miss the P&L2 min▶

You should walk in clear-eyed. Independent evidence keeps finding that a large share of generative-AI pilots show no measurable P&L impact, and analysts expect a meaningful fraction of ambitious "agentic" projects to be scrapped before they scale. That is not a reason to avoid the bet - it is a map of the potholes.

  • No baseline. The value was never measured before, so the "after" is a story, not a number. Fixable, and the reason Part 1 opens with the baseline rule.
  • No adoption. The tool works in a demo and dies in the workflow, because no one changed how the team actually does the task. Value lives in adoption, not in the license.
  • Wrong use-case. The pilot chased something flashy instead of something painful, high-volume, and low-risk. Your a2 scoring exists to stop exactly this.
Real world

The pilot that "worked" and delivered nothing. A team ran a slick forecasting-assistant pilot, declared success, and moved on. A year later the forecast still took the same number of days - because the tool never entered the monthly routine and no one had recorded the original cycle time to compare. The lesson: a demo is not a deployment, and a number you cannot compare is not a return.

✗ Ran, but proved nothing No baseline recorded before it started Demo worked; adoption never happened If it vanished, would anyone notice? ✓ Proves value before scaling One narrow, measurable use-case A baseline written down before day one A decision gate: a date and a threshold A pilot with no kill criterion never ends and never scales.
🔍 Click to zoom - a pilot without a baseline and a gate never proves anything
★ Questions to ask your team What was the "before" number, and who wrote it down? Six months in, has anyone actually changed how they do the task, or are we still doing it the old way plus a tool? If this pilot vanished tomorrow, would anyone notice - and if not, what does that tell us?

Pilot to scale, and buy vs build 6 min live

Two decisions sit under every business case. First, how to run the pilot so it can prove something. Second, how to source the capability - do you buy a tool, build your own, or blend copilots into what you have? Get these right and scaling is a formality; get them wrong and you fund a demo.

LiveA pilot that can actually prove value3 min▶

A good pilot is small, measurable, and time-boxed - designed from day one to produce a decision, not just an experience.

  • One measurable use-case. Pick a painful, high-volume, low-risk task from your a2 map. Narrow beats grand.
  • A baseline, written down. Close days, hours per report, error rate - captured before you start, by a named person.
  • Guardrails in place. The a3 rails apply from the first day: privacy, human sign-off, an audit trail. A pilot that skips governance cannot scale even if it "works".
  • A decision gate. Set the date and the threshold now: "if we cut cycle time by X with adoption above Y, we scale; if not, we stop and learn." A pilot with no kill criterion never ends and never scales.
LiveBuy vs build vs blend - the three doors3 min▶

You rarely need to build. Most finance value today comes from buying governed tools or blending copilots into existing systems. The tradeoff is always the same three dials: cost, control, and speed.

Nothing off-the-shelf fits? Does a good tool already exist? yes no yes no BUILD: full control, slow high cost, needs engineering BUY: fast, vendor-set terms predictable subscription BLEND: value in tools now fastest - it is already there Blend first, buy where a specialist tool wins, build only when the need is proven.

BlendEmbedded copilots inside Excel, ERP, or your FP&A toolOften bundled with what you ownShared with the vendorFastest - it is already thereYou want value inside existing workflows now

For most finance teams the honest answer is blend first, buy where a specialist tool clearly wins, and build only when you have proven the need and can fund the upkeep. "Build" is rarely the cheap or fast door it looks like in a vendor deck.

★ Questions to ask your team For this use-case, is there a tool we could blend into next week instead of a project we build over months? If we build, who owns it in two years when the person who wrote it has moved on? What are we actually paying for - the model, or the workflow and governance around it?
Part 3 · the artifact that unlocks the budget

The business-case one-pager 4 min live

Everything so far collapses into a single page a finance committee can read in three minutes and act on. Keep it to one page on purpose - if the case does not fit, the thinking is not done. Six sections, in this order.

LiveThe six sections, in order3 min▶
  1. Problem. The painful, specific status quo - in numbers. "Month-end close takes ten working days; three of them are manual reconciliation."
  2. Use-case. What the AI will do, narrowly. "Draft reconciliation summaries and flag anomalies for review." Not "transform finance."
  3. Cost. Licenses, setup, training time, and any build effort. Total cost of ownership, not just the sticker.
  4. Expected value. The honest metric with its baseline: "cut close from ten days to eight, redeploying ~X hours to analysis." State the lever and the "before".
  5. Risk + guardrails. The a3 rails made concrete: privacy handling, human sign-off, audit trail, and what could go wrong plus how you contain it.
  6. The ask. The specific decision you want: budget, a named pilot, a decision gate date. Make it easy to say yes.

This one-pager is the seed of the a6 roadmap: a portfolio of these, sequenced over 24 months, is your strategy. Nail one, and the next four write themselves.

The honesty test Before you present, ask: "If this delivers exactly what I wrote and no more, is it still worth it?" If yes, you have an honest case. If it only works with the optimistic slide, cut the optimistic slide.
Self-studyPresenting it in the room2 min read▶
  • Lead with the problem, not the technology. Committees fund pain relief, not novelty. The word "AI" should arrive after the problem, not before it.
  • Show the baseline first. "Here is what this costs us today" earns the right to claim a saving.
  • Under-promise the value. A modest number you hit beats a bold one you miss - and your credibility for the next four cases depends on this one landing.
  • Name the guardrails unprompted. A finance audience trusts the leader who raised the risk before they had to ask.
Exercise

Draft a mini business case ◐ 15 min · on paper

Take one use-case from your a2 map - ideally the highest-scoring, lowest-risk one - and draft its business case on a single page. You are not building anything; you are proving you can defend the value before you spend a dollar.

★ Questions to ask your team Do we have a real baseline for this, or would we be guessing? Which door - buy, build, or blend - gets us to a measurable pilot fastest? If the committee said "yes, but half the budget", what would we cut and would the case still hold?

Three questions before you go 🎯 ◐ 90 seconds

1 · Which is the most defensible way to state the value of a close-automation pilot?

Honest value is measurable: cycle-time cut and capacity redeployed against a baseline. Headcount-cut promises rarely survive reality, and vague "more strategic" claims are theatre, not a number.

2 · A big share of AI pilots show no P&L impact. What is the most common avoidable cause?

Pilots miss the P&L mostly for process reasons: no baseline was recorded, and no one actually changed how the work gets done. Both are fixable, and both are why the baseline rule and adoption come first.

3 · For a common finance need where a good governed tool already exists, which door is usually right first?

Build is rarely the cheap or fast door it looks like; it carries high upkeep and an ownership question. When a governed tool fits a common need, buying or blending gets you to a measurable pilot fastest, at predictable cost.
