Handbook: The 37signals Manager Playbook
Executive Summary
37signals hires people who can run themselves, then deliberately narrows what managers are allowed to touch — no say over pay, no approving time off, no owning conduct complaints — so the role collapses down to one thing: assessing performance honestly and saying so out loud, early and often. A single three-part framework (Skills, Engagement, Coachability) runs through hiring, onboarding, reviews, coaching, promotion, and termination, which makes the whole system legible to both sides. The core argument is that management is not overhead but compounding infrastructure: done well it retains people, protects quality, and scales judgment; neglected, it degrades the business quietly and then suddenly.
Key Vocabulary & Unique Concepts
- Manager of One: The hiring bar and the operating assumption — someone who sets their own direction and needs no supervision most of the time. It's why the playbook opens by saying management here shouldn't consume much of a manager's day.
- SEC: Shorthand for Skills, Engagement, Coachability — the single assessment framework applied at every role and level. Skills can be taught; engagement can be coached but is largely inherent; coachability governs whether either improves.
- SEC Scan: A fast HIGH/MID/LOW read across the three categories, used as a diagnostic rather than a verdict. The illustration is a brilliant but withdrawn and dismissive senior programmer who scans high-skill, low-engagement, low-coachability — which names the problem precisely enough to act on.
- Hell Yeah: The one-year retention bar. Passable performance isn't enough; the manager must be actively enthusiastic about keeping the person, and must commit to it in writing with People Ops.
- Cycle Review: An informal look-back at the end of every project cycle, using formal review standards. It exists to fill the dead zone between the one-year and two-year decision points where problems otherwise go unaddressed.
- Non-Directive Coaching: Entering a conversation with no answer in mind — open questions, reflective listening, withheld opinion — so the report reaches their own conclusion. Explicitly the harder technique, and the one that builds capacity.
- We Hire When It Hurts: Headcount follows sustained pain, not forecast. If the candidate pool doesn't produce someone convincing, hiring nobody is the correct outcome.
Deep Dive: The SEC Model
1. Skills
Mechanics: Technical ability, judgment, decision making, problem solving, project management, and communication, calibrated against a written progression framework specific to each job family and seniority level.
Function: This is the non-negotiable floor. Without it nothing else compensates — and because skills respond to coaching, a skills gap is the most fixable of the three.
2. Engagement
Mechanics: How someone shows up — energy, initiative, curiosity, ownership, accountability, independence, attitude. Assessed through visible behavior: check-in quality, willingness to run at problems, presence in team communication.
Function: Treated as inherent rather than teachable, which raises the stakes at hiring and lowers expectations for remediation. A manager can coach around it; they can't install it.
3. Coachability
Mechanics: Receptivity to feedback, growth mindset, capacity to disagree and commit, and standing within the team as a source of useful counsel.
Function: The multiplier on the other two. It's also a stated expectation for managers themselves, who are graded on seeking feedback from their reports and responding without defensiveness.
Where the model gets applied: leveling new hires, annual reviews, coaching progression, and diagnosing underperformance. Persistent high-low-low, mid-low-low, or mid-mid-low patterns are the trigger to escalate.
Deep Dive: The Underperformance Escalation Path
1. Identify and classify
Distinguish a one-time lapse from a pattern. A single crucial mistake with severe operational impact can qualify on its own; patterns earn less leniency than isolated errors.
2. Alert People Ops before talking to the report
The plan — timeline, measurable benchmarks — gets built with People Ops first. This ordering is load-bearing: the manager aligns before the report hears anything.
3. Deliver the plan directly
State what went wrong, what correction looks like, the deadline, and that the job is genuinely at risk. Support is offered, but the stakes are not softened.
4. Work the plan
Weekly check-ins with People Ops, candid running assessment. If recovery looks impossible at any point, the process moves to termination rather than running out the clock.
5. Commit to a decision
Retain or terminate. A manager who can't decide has the decision made with them by People Ops or senior leadership.
6. Run the checklist
Nearly all of it is People Ops paperwork. The manager owns two items: when the termination happens and scheduling the conversation.
7. Have the conversation, then stop
Usually under five minutes: decision, last day, reason, People Ops follow-up, one open question. If the report argues or turns hostile, refer to People Ops and end the call.
The pressure valve: at any point, a manager whose own contributor work is suffering under the weight of this can hand performance management to senior leadership. The playbook says these duties are significant but easily shed — an unusual admission, and one that removes the incentive to let problems fester out of avoidance.
Key Management Principles
Bounded authority is a feature, not a limitation
Managers have no input on compensation — salaries come from an annual Radford benchmark set at the top decile of San Francisco tech pay regardless of where anyone lives, with a floor for roles the market undervalues. Time off is informed, not requested. Complaints about conduct, harassment, or regulatory exposure end the conversation immediately and route to People Ops. Stripping these levers away removes both the favoritism risk and the excuse: what's left is assessment and communication.
Speed of feedback beats polish of feedback
Feedback is due when the manager notices, not at review time. Vague gestures ("something's not right") are useless; the prescribed form names the expected deliverable and asks what changes to hit the date. The compliment sandwich is discouraged as inauthentic. For engagement problems, the rule is behavior over person — cite the blunt tone in a specific PR, not the report that someone's hard to work with.
Coaching exists to build capacity, not to solve problems
Directive coaching is legitimate when the report lacks the knowledge, the clock is short, or exactly one right answer exists — but it scales badly and makes the manager a permanent bottleneck. Non-directive coaching, the harder discipline, requires no expertise in the subject at all. Situational coaching moves between the two. The stated payoff: teaching how to think rather than what to do compounds into a team with reputable independent judgment.
The bar is enthusiasm, not adequacy
"Hell yeah" governs both the one-year retention decision and promotion. Promotion additionally requires a business case — over-leveling relative to actual work is treated as a real failure mode, and managers are told to ask what happens if they don't promote. Because there are no merit raises or incentive pay, promotion is the only reward lever, which is precisely why the playbook warns against using it as a consolation prize.
Management compounds or it corrodes
Retention protects institutional knowledge and product momentum. Clear standards prevent judgment and ownership from blurring. Documented concerns reduce legal exposure. And culture is defined not by stated values but by manager behavior — what gets rewarded becomes aspirational, what gets ignored becomes permissible. Managers are told to keep their energy positive even about decisions they disagree with.

Practical Applications Outside People Management
- Facilitation practice: The directive/non-directive/situational taxonomy is a cleaner articulation of facilitator stance than most facilitation literature offers — and the admission that non-directive work is unnatural and requires low-stakes practice is worth borrowing for training design.
- Client engagements: The bounded-authority pattern translates directly to scoping. Naming in advance what a consultant does not decide protects the relationship more than expanding the mandate does.
- Organizational diagnosis: SEC scanning is a fast triage instrument for any group, not just direct reports. The insight that engagement fluctuates by project — and so shouldn't be read as a fixed trait from a single observation — guards against premature judgment.
- Standards and documentation: The cycle review closes the gap between formal checkpoints. Any practice with long evaluation intervals has that same dead zone, and the fix is the same: a lightweight recurring look-back using the formal criteria.
- Written culture artifacts: The playbook itself models a specific move — publishing internal management standards publicly. It functions simultaneously as an operating manual, a recruiting document, and a commitment device.
- AI as a review lens: Three chapters recommend AI for pressure-testing hiring exercises, surfacing patterns across a year of notes, and stress-testing feedback phrasing — always as a check on judgment already formed, explicitly not as a script generator or a promotion checklist.
