Direct Answer

Who: The A Method for Hiring by Geoff Smart and Randy Street (Ballantine, 2008) is the most influential operator's manual ever written on how to actually run a hiring process — not philosophy, not culture-fit theology, but a four-step playbook that PE-portfolio CEOs at Vista Equity Partners, Thoma Bravo, and Silver Lake have standardized into their value-creation playbooks.

The central thesis: a typical hiring mistake costs 15x salary (and up to 50x for senior leaders), the average manager hits only ~25% A-Players with their hires, and a disciplined process — Scorecard, Source, Select, Sell — gets you to ~90% A-Player hit rates. Smart's signature contribution is the Scorecard (mission + 5-7 outcomes + 8-12 competencies, defined BEFORE recruiting) and the voicemail reference check (the ones who call back are the signal).

The book sits in the modern hiring canon between Brad Smart's *Topgrading* (1999) — Geoff's father's source material — and Lou Adler's *Performance-Based Hiring* (2007), and remains the most-cited "how do we actually hire?" reference among growth-stage CEOs and fractional CROs.

1. 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)

2.1 Chapter 3 — The Scorecard

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

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)

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:

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)

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:

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

5. 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:

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.

FAQ

Is this book just Topgrading with a different cover? No — but it is the operator's compression. Brad Smart's *Topgrading* (1999) is the source theory and the 4-hour interview protocol. Geoff Smart's *Who* (2008) is the four-step, two-hour, PE-portfolio-friendly version most managers actually use.

Does the 90% A-Player claim hold up? It is a claim, not a peer-reviewed finding. GhSMART's internal data supports it but the methodology is not public. The directional point — that structured hiring dramatically outperforms voodoo hiring — is supported by decades of organizational-psychology research (Schmidt and Hunter, 1998).

Does the voicemail reference check still work in 2027? Voicemail response rates are way down, but the underlying signal — *do former bosses go out of their way to help your candidate?* — still works. Modern practitioners use scheduled video calls or LinkedIn voice notes for the same diagnostic.

Who actually uses the A Method today? PE-portfolio operators (Vista Equity Partners, Thoma Bravo, Silver Lake), most ghSMART clients, a large share of growth-stage tech-company CEOs, and fractional CROs/CFOs who join multi-portfolio engagements. It is under-used by mid-market sales hiring managers, which is part of why it remains an edge.

**How does it compare to Lou Adler's *Performance-Based Hiring* (2007)? Adler's method overlaps heavily on the Scorecard idea (he calls it a "performance profile") and the structured-interview approach, but Adler emphasizes the performance-based job description** and a single deep behavioral interview, where Smart prescribes the four-interview sequence.

Most practitioners blend the two.

Should sales leaders read this even if they only hire reps? Yes — the Scorecard discipline alone is worth the read. A sales-rep Scorecard with explicit Year-1 outcomes (logos, ARR, pipeline-coverage) and explicit competencies (hunter vs farmer, technical depth, channel fluency) catches bad hires earlier than any other single intervention.

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.
