Engineering Handbook Template

Overview

Teams without a written handbook reinvent their culture with every new hire. Decisions that were obvious to founders become mysteries to the tenth engineer. An engineering handbook captures the rules, norms, and reasoning that define how your team builds software. It is not a replacement for conversation. It is the reference that makes conversations productive instead of repetitive.

When to Use

• For alternatives, see SLA Definition Template.

Use this template when:

• Your engineering team is growing beyond the founding group
• New hires keep asking the same questions about process or culture
• You need to align multiple teams or office locations on shared practices
• You are preparing for an audit that requires documented engineering processes
• Team practices have evolved and need to be captured before knowledge is lost

Prerequisites

Before writing the handbook:

• Identify who owns maintenance (usually engineering manager or tech lead)
• Decide where the handbook lives (wiki, Notion, Git repo, internal docs site)
• Gather input from all current team members on current practices
• Review existing documentation and mark what is still accurate
• Set expectations: this is a living document, not a one-time project

## 3. Development Workflow

### Our Process
1. **Pick up work** — Self-assign from ready column in [ticket system]
2. **Start a branch** — Follow branching strategy (see Git Strategy doc)
3. **Write code + tests** — All code must have tests; all tests must pass
4. **Open PR** — Fill out PR template; request review from [team members]
5. **Address feedback** — Discuss, iterate, resolve
6. **Merge** — Only after approval + CI green; merge using [merge strategy]
7. **Deploy** — Follow deployment checklist; monitor after release
8. **Verify** — Confirm in production; close ticket

### Definition of Done
- [ ] Code written and tested locally
- [ ] Unit tests added/updated with >80% coverage

- [ ] Ticket closed with resolution notes

### Code Review Standards
- Review within [timeframe] of PR opening
- Approvals are required from [number] non-author engineer
- Review for: correctness, maintainability, security, performance, test coverage
- Nitpicks: prefix with "Nit:"; author decides whether to address
- Blockers: must be resolved before merge
- If you do not understand something, ask — silence is not approval

## 7. How to Change This Handbook

This handbook is maintained by [owner] and updated through:
1. Propose changes via PR to [handbook repo]
2. Discuss in #engineering or team meeting
3. Merge after consensus from [team leads / all engineers]
4. Announce changes in #engineering
5. Update onboarding materials if affected

## Changelog

| Date | Change | Author |
|------|--------|--------|
| ______ | Initial version | ______ |

Explanation

The handbook template organizes team knowledge into four areas: philosophy (why we exist), workflow (how we build), standards (what quality means), and operations (how we keep systems running). Separating these sections prevents the common mistake of documenting only process while leaving culture and technical standards implicit. The changelog and change process at the end make it clear this is a living document that evolves with the team.

Variants

Context	Adjustments	Notes
Startup < 10 engineers	Shorter; focus on principles over process	Over-documenting early creates bureaucracy
Enterprise > 100 engineers	Add compliance sections, approval matrices, cross-team interfaces	May need separate team-level and org-level handbooks
Remote-first	Add async communication norms, timezone coverage, virtual social events	Written documentation is more critical
Regulated industry	Add security, audit, and compliance sections explicitly	SOC2, HIPAA, or PCI requirements

What Works

1. Start small, expand gradually. A 5-page handbook people read beats a 50-page handbook people ignore.
2. Make it searchable. New hires look for specific answers, not a narrative.
3. Review quarterly. Outdated handbooks are worse than none; they create confusion.
4. Include reasoning, not just rules. “We do X because Y” creates understanding, not just compliance.
5. Link, do not duplicate. The handbook should reference specialized docs (runbooks, API docs) rather than include everything.

Common Mistakes

1. Writing it once and forgetting it. Handbooks rot faster than code; schedule reviews.
2. Copying another company’s handbook. Culture is context-specific; Netflix’s practices may destroy your team.
3. Making it too long. If it takes more than 20 minutes to read the essentials, it is too long.
4. Skipping the “why”. Rules without reasoning feel arbitrary and get ignored.
5. Not making it discoverable. Buried in a wiki no one checks is as good as not existing.

Frequently Asked Questions

How do we keep the handbook from becoming outdated?

Treat handbook updates as part of process changes. When a team decides to change a practice, the handbook update is the final step of that decision, not a separate task. Assign an owner who reviews quarterly. Use the changelog to track when sections were last updated.

Should the handbook be public or internal?

Engineering handbooks can be public and often serve as recruiting tools (GitLab, Buffer, and Basecamp publish theirs). Keep security, on-call contact information, and incident procedures internal. Publish philosophy, process, and technical standards externally to attract candidates who align with your approach.

How detailed should coding standards be?

Cover principles and non-negotiables (security, error handling, testing requirements). Leave formatting to automated tools (Prettier, Black, gofmt). Do not document every possible decision — focus on where the team has made intentional choices that differ from industry defaults.

Should we use a wiki or a Git repo for the handbook?

A Git repo gives you version history, pull request reviews for changes, and diff notifications. Wikis are easier to edit but lack review workflows. If your team already uses PRs for code, a Git repo creates consistency: handbook changes go through the same review process as code changes. Use a wiki only if non-engineers need to edit the handbook frequently and a PR workflow would create friction.

How do we measure if the handbook is useful?

Track how often new hires reference it during onboarding. Ask in 30-day check-ins: “Did the handbook answer your questions?” Monitor search queries if your docs site supports analytics. If the same questions keep coming up in Slack despite being documented, the handbook may be hard to find or the relevant section may be unclear.
