Most resume bullets are written backwards: they start with the task and never arrive at the result. The XYZ formula — popularized by Laszlo Bock, Google's former SVP of People Operations — fixes the order of information: accomplishment first, evidence second, method third. It's the closest thing resume writing has to a reliable recipe. Here's how it works, with worked examples across roles.
What is the XYZ resume formula?
The formula reads: "Accomplished [X] as measured by [Y], by doing [Z]." X is the outcome you achieved, Y is the number that proves it, and Z is the specific action that produced it. In practice you rarely write those literal words — the shipped bullet compresses them into one natural sentence.
Template → shipped bullet
Template: Accomplished [faster customer onboarding] as measured by [40% cycle-time reduction], by doing [building a self-service portal]. Shipped: "Cut customer onboarding time 40% by designing a self-service portal adopted by 90% of new accounts."
Why does the order matter so much?
Because recruiters scan the left edge of the page. The first three or four words of each bullet get read; the rest gets read only if those words earn it. XYZ front-loads the accomplishment and the verb, so even a partial scan collects your results. Task-first bullets ('Responsible for managing…') spend that precious real estate on filler.
What do XYZ bullets look like by role?
The formula is role-agnostic — only the metrics change. Here are before/after transformations across five common roles, each turning a duty statement into an XYZ bullet.
| Role | Before (task-first) | After (XYZ) |
|---|---|---|
| Sales | "Responsible for new client outreach" | "Booked 25 qualified demos per month (top 3 of 14 reps) through a rebuilt cold-email sequence with an 8% reply rate" |
| Admin | "Handled executive calendars and travel" | "Kept two C-suite calendars (60+ weekly meetings) conflict-free for three years while cutting average trip cost 18%" |
| Engineering | "Worked on API performance" | "Cut p95 API latency 60% by adding a Redis caching layer and rewriting the three heaviest queries" |
| Teaching | "Taught 5th grade math" | "Raised math proficiency 18 points year over year for 28 students by introducing weekly data-driven small groups" |
| Customer service | "Answered support tickets" | "Resolved 1,400+ monthly contacts at 91% satisfaction by mastering a 10-template personal call-flow system" |
How do you write an XYZ bullet step by step?
Work backwards from the result. The most common mistake is starting with Z — what you did all day — and hunting for a result to staple on. Start with what changed because you were there.
- 1List things that were different because of your work: faster, cheaper, bigger, fewer errors, happier customers.
- 2For each, find the Y — the honest number that captures the change (reconstruct it if untracked).
- 3Name the Z: the one or two specific actions that most drove the result.
- 4Draft it: strong verb + X + Y + "by" + Z.
- 5Compress to under ~30 words and cut any word that isn't information.
XYZ vs. CAR vs. STAR — which should you use?
All three are the same accomplishment-evidence-method idea at different lengths. XYZ is the compressed, single-line version built for resume bullets; CAR and STAR add context and narrative, which suits interviews and cover letters better than bullet lists.
| Formula | Structure | Best for |
|---|---|---|
| XYZ | Result + metric + method, one line | Resume bullets |
| CAR | Challenge → Action → Result | Cover letters, short interview answers |
| STAR | Situation → Task → Action → Result | Behavioral interview answers |
When should you not use the formula?
When every bullet on the page has the identical shape, the resume starts to read like output from a template — because it is. Use XYZ rigor on your best two or three bullets per role, vary sentence structure elsewhere, and let a few bullets carry pure scope ('managed a $300K budget across 25 projects') without a forced 'by doing' clause. The substance — result, evidence, method — matters more than the syntax. For more bullet raw material, see our 50+ quantified bullet examples and the full guide to quantifying achievements.
