Part One — The A Method Foundations (Chapters 1-2)

1.1 Chapter 1 — Voodoo Hiring Methods

Smart and Street open with a survey finding that has aged remarkably well: interviewers report ~50% confidence in their hiring decisions on average, yet still make the hire. They catalog the "voodoo" methods most managers actually use — the Art Critic (judges on first-impression aesthetics), the Sponge (absorbs the candidate's energy and confuses warmth for competence), the Prosecutor (drills on brain-teasers like *"how many golf balls fit in a 747?"*), the Suitor (so eager to sell the role that the interview becomes a recruiting pitch), the Trickster (asks gotcha questions to "test" the candidate), the Animal Lover (anchors on a single pet trait — "she went to Stanford"), the Chatterbox (talks past the candidate), and the Psychological (asks open-ended therapy questions and reads tea leaves).

The point is not snark. The point is that none of these methods are predictive of on-the-job A-Player performance, and most senior managers use two or three of them in combination without realizing it. The chapter ends with the book's mission statement: replace voodoo with method.

1.2 Chapter 2 — The A Method, in One Diagram

Smart introduces the four steps the rest of the book unpacks: Scorecard → Source → Select → Sell. The early-chapter framing is deliberately blunt — *"Most hiring methods are fundamentally broken. The A Method fixes them."* The authors define an A-Player as someone with at least a 90% chance of achieving outcomes only the top 10% of possible candidates could achieve. The definition matters: an A-Player is role-relative, not absolute. A bookkeeping A-Player is not a CFO A-Player. The Scorecard makes that distinction concrete.

2. Part Two — Scorecard (Chapter 3)

Part Two — Scorecard (Chapter 3)

2.1 Chapter 3 — The Scorecard

The Scorecard is the book's most-cited single artifact. It has three parts:

• Mission — a 5-8 sentence executive summary of why the role exists. Not the job description. The mission answers *what would have to be true for this hire to be a homerun?*
• Outcomes — 5-7 specific, measurable results the person must produce in their first 12-36 months. *"Grow ARR from $8M to $20M by end of Year 2"* is an outcome. *"Make the number"* is not.
• Competencies — 8-12 behavioral traits that predict the person can deliver the outcomes. Smart segments these into role competencies (analytical, strategic, persuasive) and cultural competencies (the specific behaviors your team rewards).

Smart's quoted line on Scorecards: "A scorecard is the difference between hiring on hope vs hiring on outcomes." Every downstream step — sourcing, interviewing, reference checks, the sell — references the Scorecard. Without it, the rest of the method collapses into voodoo.

3. Part Three — Source (Chapter 4)

Part Three — Source (Chapter 4)

3.1 Chapter 4 — Source

Smart's source hierarchy is the book's most counterintuitive prescription for first-time hiring managers: referrals first, ongoing sourcing second, job postings dead last. The authors document that job postings produce the lowest A-Player conversion rate of any source — typically under 5% — because A-Players are already employed and not browsing boards.

The chapter introduces three sourcing tactics:

• Ask for referrals systematically — every employee, every advisor, every customer. Ten names per ask, not "anyone come to mind?"
• Build a Deputy network — five to ten outside friends-of-the-firm who source talent in your domain year-round. Pay them or trade favors.
• Ongoing sourcing — even when you have no open seat, build a bench by talking to one potential hire per week. Smart calls this the "hire one, interview ten" habit.

The voicemail mechanic introduced later (in the Reference chapter) starts here in spirit: A-Players respond to specific, credible, named asks. They do not respond to job-board blasts.

4. Part Four — Select (Chapters 5-6)

Part Four — Select (Chapters 5-6)

4.1 Chapter 5 — The Four-Interview Sequence

The Select step is where Smart compressed his father Brad Smart's four-hour Topgrading interview into a more PE-portfolio-friendly cadence. Four interviews, in order:

1. Screening Interview (30 min, phone) — five questions: *career goals, what you're really good at, what you're not good at or interested in, last five bosses (and how they'd rate you 1-10), and why you're leaving / why interested.* The 1-10 boss-rating question is the diagnostic: candidates who self-rate every boss as "would say I'm a 9 or 10" are either A-Players or fabricators, and the gap shows up later.
2. Topgrading Interview (~2 hours, in-person) — chronological walk through every job since college. For each job: *what were you hired to do, what accomplishments are you most proud of, what were the low points, who were the people you worked with, why did you leave?* The discipline is to never skip a job and to press on the why-did-you-leave answer until the real reason surfaces.
3. Focused Interview (1 hour, per outcome on the Scorecard) — one interview per major outcome, conducted by a different team member, drilling exclusively on past evidence the candidate can deliver that specific outcome.
4. Reference Interview (multiple 15-min calls) — see Chapter 6.

The compression matters because Brad Smart's original Topgrading interview was a four-hour endurance test that few hiring managers actually ran. Geoff's two-hour version is the one PE-portfolio operators actually adopt.

4.2 Chapter 6 — The Voicemail Reference Check (Smart's Signature)

This is the chapter that made the book famous in PE circles. Smart's reference-check method:

• Pull 7-10 references, sourced from the Topgrading interview (every former boss the candidate named).
• Call each one and leave a specific voicemail: *"Hi, this is [name] from [company]. I'm strongly considering hiring [candidate] for [role]. They spoke very highly of you. Could you call me back at [number]?"*
• The diagnostic is who calls back. A-Players have former bosses who call back within 24 hours, because those bosses genuinely want to help launch the next chapter for someone they respected. Candidates whose references don't call back are flashing a red flag the candidate doesn't even know is visible.

When the references do call back, Smart prescribes five questions: *in what context did you work with them, what were their strengths, what were areas for improvement, how would you rate their overall performance 1-10, and would you hire them again?* The 1-10 question paired with the "would you hire them again" follow-up is the highest-signal pair in the chapter. A "9 — absolutely" and a "7 — probably not in this role" tell you radically different stories.

Smart also catalogs the common interviewer biases this process counteracts:

• The Halo Trap — one impressive credential (Stanford, ex-McKinsey, ex-Google) overrides all other evidence.
• The Halo Bias — close cousin: a candidate's confident or charismatic delivery in one interview anchors every subsequent interviewer to the same favorable conclusion.
• The Funnel Bias — interviewers ask broader and broader questions when a candidate is faltering, trying to "find something" to like, instead of letting the data speak.

The remedy: a shared Scorecard, independent interviewer notes, and a debrief discipline where each interviewer scores against the Scorecard before hearing the others' opinions.

Part Five — Sell (Chapter 7) and Closing the Loop (Chapters 8-9)

5.1 Chapter 7 — The Five F's

Once you've decided to make the offer, Smart prescribes selling the candidate hard against the Five F's:

• Fit — how the role connects to the candidate's career goals and life trajectory.
• Family — how the move fits the candidate's spouse, kids, and personal context. Smart insists the CEO call the candidate's spouse personally.
• Freedom — how much autonomy and decision rights the role carries.
• Fortune — the financial upside (base, bonus, equity, longer-term wealth creation).
• Fun — the team, the culture, the day-to-day texture of the work.

Most hiring managers default to selling on Fortune. Smart's data is that A-Players who join for money also leave for money, while A-Players who join for Fit + Freedom + Family build careers at the company. The Five F's are the close.

5.2 Chapters 8-9 — Building a Hiring Org and the Cultural Operating System

The closing chapters generalize: a CEO who runs the A Method on every hire eventually builds a company where every manager runs it. The book documents how to cascade Scorecards down from the CEO's direct reports to the individual contributor level, and how to use the same process for internal promotions (a promotion is a hire from inside).

Smart's final injunction is the line that has aged into PE-portfolio doctrine: "If you have to choose between hiring someone and waiting — wait." The cost of a B-Player in a critical seat is always larger than the cost of an empty seat.

Frameworks at a Glance

The named frameworks that travel directly from the book into PE-portfolio operating systems and modern hiring stacks:

• The Scorecard — Mission + Outcomes + Competencies. The most-replicated single artifact from the book; now standard in Vista, Thoma Bravo, and Silver Lake portfolio playbooks.
• The Four-Step A Method — Scorecard, Source, Select, Sell. The structural spine of the book.
• The Topgrading Interview (Smart-compressed) — Geoff's ~2 hour adaptation of his father Brad's 4-hour version. The version PE-portfolio hiring managers actually run.
• The Voicemail Reference Check — leave detailed voicemails for past bosses; track who calls back. Smart's signature mechanic.
• The Five F's — Fit, Family, Freedom, Fortune, Fun. The candidate-side close.
• The Voodoo Interviewer Catalog — Art Critic, Sponge, Prosecutor, Suitor, Trickster, Animal Lover, Chatterbox, Psychological. Used by hiring trainers to diagnose what each interviewer defaults to.
• The Halo Trap, Halo Bias, Funnel Bias — Smart's catalog of the common biases the A Method counteracts.

What Holds Up, What Has Aged

What still holds (2025-2027):

• The Scorecard discipline is the book's most durable contribution and has been adopted as the de-facto hiring artifact across PE-portfolio operating systems. Vista Equity Partners standardizes Scorecards across its 80+ portfolio companies; Thoma Bravo and Silver Lake maintain similar playbooks.
• The four-interview sequence and the voicemail reference check are still the most-recommended hiring process for senior leadership roles in growth-stage and PE-backed companies.
• The Topgrading-compressed two-hour interview survives because remote-first hiring rewards a tighter, more structured conversation than the original four-hour version.

What has aged:

• AI sourcing and screening tools — HireVue, Eightfold, Plum, Greenhouse + GoodTime, and a wave of LLM-screening startups have automated the Sourcing and initial Screening steps. The A Method's "ask for referrals" gospel still wins for senior roles, but mid-funnel candidate generation is increasingly machine-mediated.
• The voicemail mechanic itself — voicemail response rates have collapsed industry-wide since 2008. Modern Smart-derivative practitioners use the same signal but adapt it to LinkedIn voice notes, scheduled video calls, or even text-message references for younger candidates.
• Diversity and bias mitigation — the book is relatively quiet on structured de-biasing of the interview process beyond the Funnel Bias mention. Modern hiring playbooks layer in structured-interview rubrics, blind resume review, and panel-debrief norms that go beyond what *Who* prescribes.
• The Five F's "call the spouse" mechanic is now culturally awkward in many regions and industries; the underlying point (sell the candidate's whole life situation, not just the comp package) still holds.

FAQ

What is the "A Method" for hiring? The A Method is a four-step hiring process: Scorecard, Source, Select, and Sell. It replaces gut-feel recruiting with a structured approach that defines the role's mission, outcomes, and competencies before sourcing candidates, then uses structured interviews and reference checks to select top talent, and finally "sells" the best candidate on the role.

How much does a bad hire really cost? The book estimates a hiring mistake costs roughly 15 times the employee's salary, and up to 50 times for senior leaders. This includes wasted salary, lost productivity, team disruption, and rehiring costs — though actual figures vary by role and industry.

What is a "Scorecard" and why is it important? A Scorecard is a one-page document created before you start recruiting. It lists the role's mission, 5-7 measurable outcomes, and 8-12 key competencies. It forces clarity on what success looks like and prevents hiring based on vague "culture fit" or a compelling resume.

How does the "voicemail reference check" work? You call a candidate's former bosses and leave a voicemail asking them to rate the candidate on a 1-10 scale and share the biggest strength and weakness. The key insight: the ones who call back are usually the most honest and revealing references, while silence often signals a problem.

What is the typical "A-Player hit rate" without this method? The authors claim the average manager hires an A-Player only about 25% of the time using traditional methods. With the A Method, they report hit rates of roughly 90% — though this depends on consistent application and the quality of your Scorecard.

How is this book different from "Topgrading" by Brad Smart? Geoff Smart's father, Brad Smart, wrote *Topgrading* (1999), which introduced the concept of "A-Players" and structured reference checks. *Who* simplifies and streamlines the process into four clear steps, adds the Scorecard, and focuses on outcomes and competencies rather than exhaustive career histories.

Bottom Line

Read *Who* if you have ever made a senior hire you later regretted — which is every hiring manager who has ever made more than five senior hires. The book's Monday-morning takeaway: write a Scorecard before you write the job posting, run the four-interview sequence, do the reference call discipline (even if not by voicemail), and wait rather than settle. Smart's framework has become the operating-system layer of PE-portfolio hiring playbooks, the curriculum of the best executive-search firms, and the closest thing the world has to a repeatable A-Player generation process. The book sits squarely between Brad Smart's *Topgrading* (the theoretical source) and the modern AI-augmented hiring stack — and the Scorecard discipline alone is the most-cited contribution any hiring book has made in the last twenty years.
