Why AI Metrics Matter for Performance and ROI

AI measurement is becoming a governance problem, not just an analytics one. For CIOs and transformation leaders, the hard part is less choosing a metric than agreeing which metric has decision rights across the portfolio. If teams track model quality, productivity and ROI separately, leaders need a clear hierarchy that shows which indicators are for tuning, which are for adoption, and which trigger scale-up or stop decisions.

The practical trade-off is speed versus comparability. Local teams often want flexible KPIs for their use case, but the enterprise needs enough standardization to compare projects and prevent “metric shopping.” A useful question is whether each AI initiative has a business owner, a technical owner and a finance partner aligned on one benefits baseline. Without that, AI reporting can become activity tracking rather than investment control.

Metrics also shape funding discipline. AI portfolios should distinguish experiments from production services: pilots may justify learning metrics, while scaled deployments should face harder thresholds for cost, risk, reliability and business impact. That creates a management lever for reallocating budget from promising proofs of concept to the few use cases that can actually change operating performance.

Next questions for leadership are straightforward but important:

Which AI outcomes are enterprise-level priorities versus local optimization?
Who can approve a move from pilot funding to scale funding?
What evidence is required before benefits are counted in forecasts?
How will the organization prevent metric inflation, duplicate tooling and hidden run costs?

Handled well, AI metrics become part of operating model discipline: they link technology decisions to funding, accountability and value realization rather than leaving each team to define success on its own terms.

As a growing number of organizations embrace AI, many are discovering that getting a handle on the technology’s performance attributes can be challenging, to say the least, particularly when it comes to generative AI.

We’ve found that most IT leaders are not currently on the same page about generative AI key performance indicators (KPIs,) says Jim Rowan, AI market activation leader at business advisory firm Deloitte. "Given that the technology is rapidly evolving, and its adoption is exponentially accelerating, the KPI landscape is likely not mature enough to get a clear picture of how leaders are measuring value — and how they should be measuring value."

Still, as organizations increasingly invest in GenAI to power their digital transformations, business leaders are eager to demonstrate the value of these investments, Rowan says in an email interview. "Without the right measurements in place, individual tech investments can be undervalued or underfunded, wasting valuable resources, missing opportunities for growth, and fueling misaligned expectations."

A Strong Foundation

Measurement is the cornerstone of both good science and engineering, and AI is no different, says Eric Heim, chief scientist, AI division, at Carnegie Mellon University’s Software Engineering Institute in an email interview. He notes that measuring provides evidence to support or refute AI performance claims. "In other words, if done correctly, it gives you insight into how AI will perform when used in the real world." What makes measurement vitally important for AI, Heim says, is that most modern AI does not have strong principles to fall back on if success can’t be measured.

GenAI and KPIs

GenAI is a complicated topic in terms of KPIs because it can be leveraged to bring value in many ways, says Shelia Anderson, CIO at supplemental insurance company Aflac, in an online interview. "Generally, we use two sets of metrics — technology-aligned and business-aligned," she states. "There are multiple KPIs that are important to us — we consistently have key business goals aligned to KPIs that are jointly owned with the business and show clear delineation of value as aligned to business expectations," Anderson says. "GenAI is changing the way we work, so measuring that impact is of particular importance."

Organizations using GenAI to measure productivity should closely monitor expense reductions, says Barbara H. Wixom, a principal research scientist at the MIT Center for Information Systems Research (CISR). "Productivity improvements can be a useful KPI in the sense that it might be a leading indicator of future expense reduction, but expense reduction is the most important KPI," she states in an email interview.

Meanwhile, organizations using GenAI to create new products or enhance the value of existing products should closely monitor the bottom line, says Cynthia M. Beath, an academic research fellow with MIT CISR, via email. Are sales, for instance, increasing more than expenses? "Customer satisfaction, customer retention, or reduced service expenses might be useful KPIs if your organization understands how changes in those KPIs translate into future bottom-line impact." On the whole, however, product profit and loss is the most important KPI, she says.

Other Factors

To maximize productivity, GenAI should be seamlessly embedded within business processes and systems, says Manisha Khanna, AI strategist at analytics software firm SAS. "Performance should be reliable, transparent and ethical, accelerating productivity and improving customer experience, while adding measurable value to stakeholders," she advises via email. "A top KPI for GenAI focuses on reliability, including validating and ensuring response consistency to known prompts."

Validating and ensuring consistency in foundation models’ responses to known prompts is essential for determining the reliability of foundation models and for contributing to a better user experience, Khanna says. "This is especially critical when GenAI is used in regulated markets or in high-risk use cases that affect humans and society." She adds that it’s important to understand the value realized from GenAI investments. "That means getting visibility into the components and associated costs that span across a model provider, cloud infrastructure and application provider."

Gaining Visibility

It’s important to understand the value realized from GenAI investments, says Alain Biem, chief data science officer at life insurance firm New York Life, in an email interview. The top KPI for GenAI is return on investment (ROI), he states. "ROI summarizes the targeted business value — revenue, productivity, or cost saving — versus the deployment cost — development, maintenance, and opportunity cost." Biem notes. "In terms of a leading KPI, ROI is the best assessment of the overall value of technology, its adoption, and impact to the company bottom line."

Final Thoughts

Practically speaking, AI is costly, yet by itself it guarantees no payback, Wixom says. "Like any tool, AI must be used for it to pay back the investment."

Heim, meanwhile, believes that AI metrics application should be guided by whatever is most important to its user. "For instance, for question answering, factualness is important," he notes. "For fantasy writing, factualness is not as important."
