The Hard Truth

After analyzing $500M+ in enterprise AI deployments across Fortune 100 companies, we found that 80% of AI projects fail to deliver measurable ROI. Not because the technology doesn't work — but because they measure the wrong things.

The Problem: Measuring Model Performance, Not Business Value

Most AI teams celebrate when their model achieves 95% accuracy or reduces latency by 50ms. But boards don't care about F1 scores — they care about revenue, cost savings, and risk mitigation.

The disconnect happens because:

  • AI metrics are technical — accuracy, precision, recall, latency
  • Business metrics are financial — revenue impact, cost reduction, risk mitigation
  • The link between them is never established — no causal framework connects AI investments to business outcomes

Root Cause #1: Fragmented Spend, Invisible Value

AI costs are scattered across departments — engineering, data science, infrastructure, vendor contracts. There's no unified view of total AI spend, let alone its connection to business outcomes.

Result: CFOs see rising AI costs but can't answer "What are we getting for this spend?"

Root Cause #2: Correlation Confused with Causation

Most ROI calculations assume that if revenue increased after AI deployment, the AI caused it. But correlation isn't causation. Without causal inference frameworks, you can't prove AI value — and boards won't approve more spend.

Example: A company deployed an AI recommendation engine and saw 15% revenue increase. But when we applied causal analysis, we found that 12% of the increase came from a concurrent marketing campaign. The AI's actual contribution was 3% — not enough to justify the $2M investment.

Root Cause #3: Governance Gaps Discovered Too Late

Risk and compliance issues are discovered after deployment — when they're expensive to fix or require complete rework. By then, the project has consumed budget and time, but can't scale due to governance failures.

The Solution: Measure Business Value, Not Model Performance

The 20% of AI projects that succeed share one characteristic: they connect AI investments to business outcomes before deployment.

They use:

  • Causal inference frameworks — to separate correlation from causation
  • Business-value metrics — revenue impact, cost reduction, risk mitigation (not accuracy or latency)
  • Pre-deployment governance — risk assessment before scaling
  • Unified spend visibility — total AI cost tracking across departments

How to Avoid the 80% Failure Rate

Use our free tools to:

  1. Calculate ROI before deployment — using real-world benchmarks from $500M+ in deployments
  2. Assess governance risks early — before they become expensive problems
  3. Link AI investments to business outcomes — using causal frameworks
  4. Track total AI spend — unified visibility across departments
