People investments work. How to partner with your CFO to prove it

The first time a CFO saved one of my programs, I was in a budget review walking through the business case for a leadership development initiative. I had solid numbers: cohort sizes, projected retention lift, a ramp-time model.

I was braced for scrutiny when the CFO leaned forward and said, "I went through a program just like this and it was one of the most useful things the company has ever done for me."

I think about that moment often, as it contradicts the popular perception that the CFO is the skeptic itching to say “No.”

In my experience, that’s not the full picture. Yes, the CFO is laser-focused on financial health. But they're also a leader trying to build a high-performing team under the same pressures as everyone else. Get their support early and you’ll have less convincing later.

Most CHROs I know are already aligning their roadmap to the business agenda and reporting on retention, productivity, and risk to the board. That’s the hard part, and they’re fluent enough in finance to hold their own. The real question is whether their teams can connect equally well with the CFO's team.

The collaboration gap, when it exists, is usually a few layers down. Some signs to watch for: your head of talent and your head of FP&A rarely sit in the same room. Your HR business partners and finance leads are working from different definitions and different data. HR has a strong productivity claim but finance can't tie it to a cost center, or retention means one thing on your scorecard and something else on theirs.

Over time, that misalignment erodes finance's trust in HR's numbers. When a CFO pushes back on a people program, it's often because the case was never built collaboratively at the ground level. The fix is bringing finance into the program design early enough that they become your co-authors, not your judges.

Refining the business case: a three-step framework

You already know what a good business case looks like. The three steps below can help pressure-test what you’re already doing while giving HR and finance partners a shared framework.

1. Alignment. Start with the business agenda you’ve already been handed: growth target, retention, AI adoption, margin pressure. If the initiative doesn’t map to the official agenda, it will read as unnecessary.

2. Measurement. Define a leading indicator you can measure reliably and repeatedly, before and after the program, by cohort. Resilience, for example, can be measured as retention (employees at end of period ÷ employees at start of period × 100) or absenteeism (hours lost to absence ÷ total scheduled hours × 100). The goal is to connect what you already measure to what finance already measures, and to agree on the formula with finance before the first report runs.

3. Attribution. Tell a clear story about what changed and why. You don't need perfect causation, but you do need to show that results hold when you slice the data by team, role, and region. For example, teams with higher adaptive performance may complete priority projects faster, propelling revenue growth or cost efficiency. That bridge between behavioral data and business metrics is what lets you and your finance team work from the same numbers.

Anchor your initiative in the CEO's agenda, pick two to four leading indicators you can measure by cohort, and translate expected outcomes into dollars: attrition savings, time-to-productivity, revenue per FTE.

For example, when we worked with John Muir Health, retention was already on the CFO's desk as a cost driver, so the metrics were straightforward: attrition and performance scores, tracked pre and post by cohort. Participants showed 62% lower attrition and 16% higher performance scores. Translated into dollars, the program returned 13X on investment.

Three ways to bring finance in earlier

The framework above works best when finance isn't seeing it for the first time in a budget review. When they're involved in building the program, they're more inclined to defend it than poke holes.

1. Partner with them on the pilot. Ask your CFO which part of the business they'd most want to see the new program tested on: a function they watch closely, a team on their concern list, a leader whose performance they’re unsure of. If they pick the focus, they’ll have a stake in the outcome.

2. Co-author the success criteria. Before the pilot launches, sit down with the CFO and agree, in writing, on what 'this worked' looks like. Which indicators, which formulas, which cohort definitions, what reporting cadence. When the data comes in, there is nothing to debate.

3. Share snapshots of the progress, not just end results. Don't wait until the pilot is over to report out. Share results monthly, the good and the bad. Finance leaders are more comfortable with a running scorecard than a surprise ending.

From behavior change to business impact at scale

The business case for workforce development keeps getting stronger. In 2023, University of Oxford researcher Jan-Emmanuel De Neve and colleagues analyzed 1,782 publicly traded companies and found that employee wellbeing reliably predicts both financial and stock performance. Over 3.5 years, the top 100 wellbeing-rated companies delivered annualized returns of 14.84%, outperforming the S&P 500's 13%. This is the kind of stat your team should keep loaded in their back pocket.

But evidence alone doesn't close the gap. The real test is whether the case you build survives the trip from your team to the finance team to the CFO's office with its definitions and credibility intact. That takes shared metrics, shared ownership, and a CFO who was in the room before the numbers were final. Build it that way, and you're not pitching a people program. You're presenting an investment your finance team already believes in.
