## A working definition

Worth a slow read.InfoSum is an audience or privacy concept your team should define once. A loose definition misaligns budgets and reporting.

Data clean room provider

InfoSum sits in Audience & Privacy; it is an audience or privacy concept. Define it once and the reporting holds together.

## How it operates

Start here.InfoSum works one way for a lean team and another for a large one. The mechanics follow the context.

InfoSum behaves unlike a fixed rule. An early-stage brand and a mature one will apply InfoSum on different terms. The mechanics follow the inputs around it. Treat InfoSum as a buzzword and the reporting misleads; agree on it and the numbers hold.

Keep the order simple: define InfoSum for your context, then decide how to act. Reverse it and the budget chases a number nobody agreed on. Hold that thought.

## Where it shows up

Look at it this way.Bring InfoSum in when a live call depends on it. With no decision on the table, it stays background.

Bring InfoSum in when a live choice hangs on it. In audience & privacy work, that usually means one of three moments. Away from a decision, InfoSum is background, not a lever.

1. **Setting budget.** InfoSum clarifies which budget line deserves more.
2. **Choosing a metric.** InfoSum reveals if the metric measures real impact.
3. **Comparing options.** InfoSum corrects two options that look alike but are not.

## A worked example

Read that twice.To make InfoSum concrete, the case below uses Nike and figures from public reporting plus RGM analysis.

Take Nike. During a clean-room measurement setup, the team made InfoSum the deciding input, not an afterthought. They set a baseline first, agreed one definition of InfoSum, and only then read the result: cross-channel reach stayed within 5% of truth. The number matters less than the order.

Example walk-through for InfoSum -- figures illustrative, RGM analysis

| Stage | Action | What it bought |
| Baseline | Took a before reading on InfoSum. | Something concrete to compare to. |
| Define | Agreed a single definition of InfoSum. | A shared definition up front. |
| Act | A clean-room measurement setup — one variable. | One change, a clean read. |
| Result | Cross-channel reach stayed within 5% of truth | A call backed by the read. |

These InfoSum numbers are illustrative -- RGM analysis. The structure travels; the specific figures do not.

## Common mistakes

Start here.Teams slip on InfoSum in four familiar ways. Each makes a soft assumption look like a precise number.

- **One blanket rule.** Applying InfoSum the same way everywhere. Split it by audience, channel, and business model.
- **No context.** Reporting InfoSum with no baseline. A bare number cannot be judged.
- **Vanity focus.** Gaming InfoSum instead of the result. Tie it to business value.
- **Raw benchmarks.** Stacking InfoSum against rivals blind. Normalize for margin, pricing, and sales cycle.
