One Directorate, Five Versions of the Truth. Which Data Do We Trust?

We say we are data-driven. Then a meeting starts, and Team A brings a number that differs from Team B's. Team C has its own dashboard. Team D trusts a spreadsheet described, with impressive confidence, as the latest version.

The meeting stops being about strategy. It becomes a discussion about whose numbers deserve to be believed. Everyone has evidence. What nobody has established is whether the evidence answers the same question.

This does not automatically mean somebody made a calculation error. Different teams may be describing different parts of the business, using labels that make those differences almost invisible.

One label, several meanings

Consider revenue. Does it mean contracted value, issued invoices, or transactions that meet the relevant recognition rules? The reporting period, treatment of cancellations, and customer scope may also vary.

Each view can be useful. Trouble begins when they share a column heading and are presented as interchangeable. Ordering coffee without specifying the kind produces a similar problem: the category is clear, but the actual expectation remains open to interpretation.

Multiple sources are not inherently a failure. Operational systems, financial records, and commercial analysis serve different purposes. A shared source of truth should explain their relationship, rather than pretend every business question needs an identical dataset.

Governance people can actually use

Start by assigning an owner to each metric. The owner is not simply whoever emails the report most recently. Someone needs responsibility for its definition, source, changes, and appropriate uses.

Next, create a shared metric dictionary. Include the formula, reporting period, unit, scope, exclusions, and refresh timing. A short reference that people consult is more valuable than an elaborate policy that appears only when somebody asks whether a policy exists.

Establish trusted reference datasets for particular decisions. The reference for billing may differ from the reference for monitoring sales opportunities. Users should understand why, and what adjustments are necessary before comparing them.

Then agree on reconciliation. When numbers disagree, who investigates? What evidence is needed? How is a material difference escalated, and which decisions can proceed while the investigation continues? Without these rules, every discrepancy can become another meeting invitation.

Keep the process proportionate. A difference that changes a commercial decision deserves attention. A rounding difference that changes nothing probably does not need an expanding committee. The purpose is dependable judgment, not the elimination of every visible decimal mismatch.

Agreement is only useful if someone decides

Matching numbers do not automatically create accountability. Teams still need to know who makes the decision, who contributes advice, and which assumptions should be recorded when information remains incomplete.

Some discrepancies need further investigation. Others can be handled through an explicit limitation or a documented adjustment. Distinguishing between them helps an organization avoid confusing analytical caution with permanent indecision.

This requires collaboration. Business teams should explain the decisions they need to support. Data teams should explain how the figures are produced. Process owners should identify operational changes that affect the agreed definitions.

Record the agreement somewhere people can find it. Include an effective date, a responsible owner, and a change history. Readers of an older report should not have to discover by accident that the meaning of its central metric has changed.

A closing perspective

Another dashboard may improve presentation. It cannot replace agreement about what the numbers mean or who is accountable for acting on them.

Perhaps the next useful investment is a shared reference for a specific decision, supported by clear ownership and reconciliation. A single source of truth should not become a single source of debate.
