Achievement Mining: How to Quantify Your Resume Bullets

You know you’re good at your job. You’ve done real work. Solved real problems. Made real things happen.

But when you sit down to write your resume, all that comes out is: “Managed client relationships” and “Responsible for project delivery.”

That’s not a resume. That’s a job description. And every single person who’s ever held your title has the exact same bullet points.

The difference between a resume that gets ignored and one that gets interviews? Numbers. Specific, quantified achievements that prove your impact.

I’ve spent hundreds of hours in coaching sessions doing what I call “achievement mining,” which is the process of digging through someone’s work history and pulling out the numbers that were there all along. And I can tell you this: everyone has them. You just haven’t found yours yet.

Let’s fix that.

Why Numbers Change Everything

Hiring managers scan your resume in 6 to 8 seconds. Their eyes move in an F-pattern: top left, sweep right, drop down, sweep right again, then skim down the left side.

Numbers interrupt that scan. They catch the eye. A recruiter skimming past “managed email campaigns” will stop dead at “$2.3M in new revenue.”

That’s not an opinion. Eye-tracking studies on recruiters confirm it. Numbers at the beginning of a bullet point get noticed. Everything else gets skimmed past.

So the question isn’t whether you should quantify your resume. The question is how.

The XYZ Formula: Your New Best Friend

Laszlo Bock, former Google SVP of People Operations, created this formula in his book Work Rules!, and it’s become the gold standard for resume writing. Every achievement on your resume should follow one structure:

Achieved X, as measured by Y, by doing Z.

• X is the result. What happened because of your work.
• Y is the metric. The number that proves it.
• Z is the action. How you made it happen.

Here’s how it works in practice:

Before: “Managed social media accounts and created content.”

After: “Grew social media following from 12K to 89K across 3 platforms, generating 1,400 inbound leads per quarter, by creating a daily content calendar and engagement strategy.”

X = Grew following from 12K to 89K.
Y = 1,400 inbound leads per quarter.
Z = Daily content calendar and engagement strategy.

The formula forces you to go beyond what you did and into what happened because you did it. That’s the shift.

And here’s the key: put the biggest number first. Lead with it. Because if the recruiter only reads the first four words of your bullet, you want those four words to be “Grew revenue by $67M” and not “Responsible for supporting.”

The 5 Dimensions of Quantification

When I coach people through achievement mining, I use five dimensions. These are five different lenses for finding numbers in any role, even roles that feel unquantifiable.

1. Volume

How many? This is the most straightforward dimension.

• How many projects did you complete?
• How many clients did you manage?
• How many campaigns did you run?
• How many reports did you generate?
• How many people did you train?

If you worked on “many projects,” that’s not good enough. Was it 5 or 50? There’s a massive difference, and hiring managers need to know which one.

2. Time

How fast? How long? Time is money, and employers know it.

• How many hours of labor did you save through automation or new processes?
• How quickly did you complete something compared to the timeline?
• How many years of experience do you bring to a specific area?
• How did you reduce turnaround time?

If you built a process that saved your team 3 hours a week, that’s 156 hours a year. Multiply that by the average hourly cost of an employee, and suddenly you saved the company $15,000+ annually. That’s a resume bullet.

3. Money (Earned or Saved)

Revenue and cost savings are the universal language of business impact.

• How much revenue did your work generate?
• How much money did you save the company?
• What size budget did you manage?
• What was the value of the deals you closed?

Even if your role wasn’t directly tied to revenue, there’s usually a money number hiding in there. More on how to find it below.

4. Scale

Scale tells the story of complexity and reach.

• Did you work at a local, national, or international level?
• What size were the companies you worked with?
• How many people were on the team you managed or supported?
• How many locations, departments, or regions were involved?

“Managed a project” is vague. “Managed a cross-functional project spanning 4 departments and 3 countries” tells a completely different story.

5. Rank

Rank is your secret weapon for standing out.

• How did your performance compare to peers?
• What was your ranking on the team?
• Did you win any awards or recognitions?
• What was your success rate compared to the average?

When Anil, one of my coaching clients, told me he resolved 30 to 40 insurance cases per day with a 92% success rate and near-100% customer satisfaction, those rank numbers completely transformed his resume. Before that, he had “handled policyholder inquiries.” After? “Resolved 200+ monthly policyholder inquiries with a 92% success rate, maintaining near-perfect customer satisfaction through a systematic follow-up process.”

Night and day.

The “If You Weren’t There” Test

This is my favorite framework for uncovering hidden achievements, and it works for any role.

Ask yourself: If I wasn’t there and I didn’t do this work, what would have happened?

Would things have fallen apart?
Would deadlines have been missed?
Would errors have gone uncaught?
Would customers have been lost?

Sandra, a developer advocate I coached, initially described her work as “created educational blog content” and “organized developer demos.” Vague. Forgettable.

But when I asked what would have happened without her, the real story came out. She had built proactive documentation and FAQ resources that reduced customer support inquiries by 50%. She had run workshops teaching API best practices that saved $6,000 per day in unnecessary costs.

$6,000 per day. That’s $180,000 per month. Same work she’d been describing as “organized demos.” The impact was always there. She just hadn’t framed it.

Whatever you do at work, something depends on you doing it well. Find that thing. Quantify it.

How to Estimate When You Don’t Have Exact Numbers

This is where most people get stuck. “I don’t remember the exact numbers” becomes “I can’t quantify my work.” But that’s not true.

You don’t need exact numbers. You need educated estimates.

Here’s the narrowing technique I use in every coaching session:

Start wide, then eliminate the extremes.

That took 30 seconds. And now instead of “worked on various projects,” they can write “managed approximately 10 concurrent projects per month.”

This isn’t lying. This is making an educated estimate that paints a picture. Nobody’s going to check these data points and call you out if the number is slightly different. It wasn’t 10 projects per month, it was 8, so you don’t get the job? That doesn’t happen. The goal is to help the employer understand the scope and scale of your impact.

A conservative, realistic estimate is infinitely better than no number at all.

The Listerine $67M Framework: A Real Coaching Example

This is one of my favorite examples of how achievement mining works in real time.

David came to a group coaching session with this on his resume: “Increased Listerine Go Tab sales by 30%.”

Fine. But it’s missing all the good stuff.

I started digging:

The final bullet: “Boosted Listerine Go Tab sales by 50%, driving $67 million in additional revenue and 200K units sold, through a guerrilla sampling campaign across 74 events in Toronto and Montreal.”

Compare that to “Increased Listerine Go Tab sales by 30%.”

Same person. Same experience. Completely different impact. The $67 million was always there. David just hadn’t done the math.

Real Examples from Coaching Sessions

Derek: From “Helped Build” to Direct Ownership

Derek kept using weak language on his resume. “Helped build the team.” “Helped increase revenue.”

The first thing I told him: stop saying “helped.” Focus on what you directly own.

When we dug into his real estate brokerage work, here’s what we found. He’d grown the team in Bradenton, Florida by 50%, adding 5 new agents. How? By networking at events, inviting agents to team meetings, and connecting them with leadership.

Before: “Helped build the brokerage team in Florida.”

After: “Grew the Bradenton Florida team by 50% (5 new agents) by recruiting at networking events and introducing prospects to EXP’s leadership team, enabling the team to better distribute thousands of incoming Zillow leads.”

The XYZ formula unlocked the whole thing.
X = grew team by 50%.
Y = 5 new agents.
Z = recruiting through networking events and leadership introductions.

Linh: Mining Achievements from HR and Events Work

Linh felt like her work was too “soft” to quantify. She’d organized company socials and run a volunteer HR community. How do you put numbers on that?

By asking the right questions.

Final bullet: “Contributed to the success of a new hybrid work model by launching monthly company socials within the first four weeks on the job, achieving 80% attendance with approximately 30 attendees per session.”

Her volunteer HR community: How many members? 400. How many events have you run? Over 40 monthly events across 3+ years. Average attendance? 18 to 22 per month.

Final bullet: “Founded and led a volunteer HR community of 400 members, hosting 40+ monthly events over 3 years with 18-22 active attendees per session.”

Linh’s reaction when we wrote that: “Can I say I established it?” Absolutely. She founded and leads it. That’s ownership. Own it.

Brandon: Reframing Technical Work as Business Impact

Brandon is a developer. His resume was full of technical specs. Languages, frameworks, tools. All “what” and no “so what.”

When I asked him to tell me about his Umbraco project, he started describing the CMS architecture. I stopped him.

“What happened because you built this?”

It turned out 10 to 12 different clients within the company could now go into the solution, build their own websites, and customize them without involving engineering. Brandon had built extensive documentation that made the whole thing self-serve.

That’s a legacy. He created an asset the company uses long after he’s gone.

Before: “Built a web content management system using Umbraco.”

After: “Enabled 12 clients to independently build and launch customized websites without engineering support by developing a self-serve Umbraco platform with thorough documentation, reducing client time-to-launch by an estimated 80%.”

The impact was always there. Brandon just thought the technology was the story. It wasn’t. The 12 self-sufficient clients were the story.

The Achievement Mining Process: Step by Step

Here’s the exact process I use in coaching sessions. You can do this on your own, or grab a friend to ask you the questions (it’s way easier to tell someone else your stories than to try to remember them alone).

Step 1: Pick a Role

Start with your most recent position. You’ll have the freshest memory and the most relevant material.

Step 2: Break Down the Job Description

Take every sentence from your job description and turn it into a question. “Managed cross-functional teams” becomes “When did I manage cross-functional teams? How many people? What did we deliver?”

If you want to speed this up, paste the job description into your AI assistant with this prompt: “Break this job description down sentence by sentence. For each sentence, ask two questions about how a candidate might demonstrate that experience.”

Step 3: Answer Each Question with a Specific Example

For each question, think of one concrete situation. Not “I did this kind of thing regularly” but “In Q3 of 2024, I did this specific thing and here’s what happened.”

Step 4: Run Through the 5 Dimensions

For each example, ask: What’s the Volume? The Time? The Money? The Scale? The Rank? You won’t have all five for every achievement, but you’ll usually find at least two.

Step 5: Apply the XYZ Formula

Take your answer and structure it as: Achieved X, as measured by Y, by doing Z. Put the most impressive number first.

Step 6: Get Comfortable with Estimates

If you don’t have the exact number, use the narrowing technique. Eliminate the extremes and land on a conservative estimate you can say confidently.

Putting It All Together: Build Your Master Achievement Bank

Don’t just write 3 to 4 bullets per role and call it done. Build a master resume with every achievement you can mine from every role. I’m talking 8 to 10 achievements per position.

Then, for each job you apply to, select the 3 to 5 most relevant achievements for that specific role. Tools like Teal (the free version) let you toggle achievements on and off for different applications without rewriting from scratch.

Structure your achievement count by recency: 4 to 5 bullets for your most recent role, 3 for the one before that, 2 to 3 for everything earlier. Remove roles that aren’t relevant.

This is the curated approach to job searching. Instead of sending 200 generic applications, you send 20 targeted ones where every bullet on your resume directly maps to what they’re looking for. That’s how you go from 600 applications with zero interviews to landing interviews in weeks.

Your Micro-Action for Today

Open your resume right now. Pick one bullet point that starts with “Responsible for” or “Managed” or any other job description language.

Ask yourself these questions:

1. How many? (Volume)
2. How fast or how long? (Time)
3. How much money? (Money)
4. How big or how complex? (Scale)
5. How did I compare? (Rank)

Rewrite that one bullet using the XYZ formula: Achieved X, as measured by Y, by doing Z.

One bullet. One number. Start there.

Frequently Asked Questions

What if my role genuinely doesn’t have measurable outcomes?

Every role has measurable outcomes. I’ve coached people in HR, administration, teaching, customer service, creative fields, and government. The numbers are there. You just need to look differently. How many people did you support? How many processes did you create or improve? How much time did you save? What was the error rate before and after you implemented something? If you truly can’t quantify a specific achievement with a number, describe the scope instead: team size, number of stakeholders, geographic reach, project complexity. But nine times out of ten, the numbers are there when you start asking the right questions.

Is it okay to use estimates on my resume? Won’t I get caught?

Using educated estimates is not only okay, it’s standard practice. Nobody expects you to remember that you handled exactly 847 support tickets in Q2 of 2023. What matters is scope. Were you handling 5 per week or 50? That difference matters, and a reasonable estimate communicates it. The key word is “reasonable.” Don’t claim you saved $10 million if it was $100K. But if you saved somewhere between $80K and $120K and you write “$100K+,” that’s an honest, defensible estimate. In my experience coaching hundreds of clients, not a single one has been challenged on a reasonable estimate in an interview.

How many quantified bullets should I have on my resume?

Every bullet should ideally include at least one number. If you have 15 bullet points across your resume, aim for numbers in at least 12 of them. The remaining 2 to 3 can describe scope or context without a specific metric. For your most recent role, aim for 4 to 5 strong, quantified achievements. For the role before that, 3. For older roles, 2 to 3. And remember: quality over quantity. One bullet that says “Drove $2.3M in new revenue through a targeted ABM pilot across 50 enterprise accounts” is worth more than five generic bullets about responsibilities.
