## AI overview

This article argues that Single Source of Truth initiatives often fail because teams use different definitions for shared business metrics. It presents governance, business ownership of KPI definitions, and alignment between teams as more important than centralizing tables, pipelines, or dashboards.

## Source excerpt

"We have multiple dashboards showing different numbers. Which one is correct?" If you've worked in data long enough, you've probably heard this question more times than you'd like. Sales reports one revenue figure. Finance reports another. Product Analytics has a third. Executives spend more time debating whose dashboard is correct than discussing what action to take. The natural response is often: "Let's build a Single Source of Truth." Sounds simple. Build a few centralized tables. Move everyone onto the same dashboards. Problem solved. Except...it rarely is. After leading an enterprise-wide Single Source of Truth (SSOT) initiative, I learned an important lesson: The hardest part wasn't building pipelines or writing SQL. It was aligning people. Technology was the easy part. Changing how the organization thought about data was the real challenge. The Biggest Myth About Single Source of Truth Many organizations believe an SSOT is simply a technical project. The thinking usually goes like this: Collect Data ↓ Transform Data ↓ Build Gold Tables ↓ Everyone Uses Them Unfortunately, reality looks more like this: Different Teams ↓ Different Definitions ↓ Different Dashboards ↓ Different Decisions ↓ Lost Trust The problem isn't that data lives in different places. The problem is that different teams define the same business metrics differently. Figure 1: Moving from fragmented metric definitions to a trusted Single Source of Truth is as much about standardization and governance as it is about technology. A table cannot solve that. Only governance can. Technology Doesn't Create Trust Imagine a metric as simple as Revenue. Ask five departments what "Revenue" means, and you might receive five different answers. Finance may recognize revenue after invoicing. Sales may count closed deals. Marketing may include projected pipeline. Product Analytics may track subscription purchases. Customer Success may exclude refunds. None of them are necessarily wrong. They're answering differen
