Lead With Impact

A brag document that lists what you did reads like a job description. A brag document that leads with what changed reads like a promotion case. The difference is impact-first framing: state the outcome before the activity, so the reader knows why the line matters before they reach how it happened.

Activity versus impact

Activity answers "what did you do?" Impact answers "what changed because you did it?" Compare:

• Activity: "Refactored the checkout service."
• Impact: "Cut checkout errors by forty percent, recovering an estimated quarter-million in abandoned orders — by refactoring the checkout service."

The second version front-loads the number your manager cares about, then attaches the work as the mechanism. Same effort, radically different signal.

The four currencies of impact

Most impact lands in one of four currencies. When you log a win, ask which one it moved:

• Revenue — sales won, conversion lifted, churn reduced, deals unblocked.
• Cost — spend cut, hours saved, headcount avoided, waste removed.
• Risk — outages prevented, compliance closed, security hardened, single points of failure eliminated.
• Speed — cycle time shortened, launches accelerated, decisions unblocked.

If a win does not obviously touch one of these, ask the next-level question: who downstream benefited, and how would they describe the change?

Quantify, then estimate, then characterize

The strongest impact is measured. The next strongest is a reasonable estimate with its assumptions stated. The weakest — but still useful — is a qualitative characterization tied to a named beneficiary.

1. Measured: "Reduced page load from 4.2s to 1.1s."
2. Estimated: "Roughly twenty hours a week saved across the support team."
3. Characterized: "The on-call rotation went from dreaded to routine, per the team's retro."

Reach for the highest rung you can honestly support. A confident estimate beats a vague superlative every time.

Capture impact while it is fresh

The reason impact-first framing fails is not skill — it is memory. By review season the numbers have evaporated. Log the win the week it happens, with the metric attached, while you can still pull the real figure. A win captured with its number is worth ten reconstructed from memory.

The one-line test

For each entry, ask: if my manager read only this sentence, would they understand why it was worth my salary? If the answer is no, you are still describing activity. Rewrite until the outcome leads.
