Update Component Ownership Model handbook with detailed procedures and validation

Overview

The Component Ownership Model handbook provides high-level guidance on the model and the "From Idea to Production" runbook, but feedback from the pilot rollout indicates that the documentation needs to be expanded with more detailed procedures, examples, and validation steps. This issue tracks improvements needed to make the handbook a comprehensive resource for teams adopting the model.

Current State

The handbook exists at: https://handbook.gitlab.com/handbook/engineering/infrastructure/production/component-ownership-model/

Current sections include:

• Overview of the Component Ownership Model
• "From Idea to Production" runbook with high-level steps

Gaps Identified

1. Insufficient Detail in Procedures

• The "From Idea to Production" runbook exists but lacks detailed step-by-step guidance
• Many procedures reference external documentation but don't provide enough context
• Teams need more concrete examples and walkthroughs

2. Missing Integration Procedures

• Vault setup procedures need to be documented or linked
• Helmfile and infra-mgmt onboarding procedures need to be documented or linked
• Observability setup procedures need to be documented or linked
• Metrics catalogue procedures need to be documented or linked

3. Lack of Validation Steps

• No clear guidance on how to validate that each step was completed successfully
• Teams don't know what "done" looks like for each phase
• No troubleshooting guidance for common issues

4. Outdated or Inaccurate Information

• Some procedures may no longer be accurate after the pilot rollout
• Need to verify all procedures are current and reflect actual processes

5. Missing Examples and Templates

• No examples of actual configuration files or changes
• No templates for common tasks
• Teams must search for examples in existing projects

Goals

Create a comprehensive handbook that enables teams to:

1. Understand the complete Component Ownership Model process
2. Follow detailed procedures for each phase (idea, development, staging, production)
3. Know what success looks like at each step
4. Find examples and templates for common tasks
5. Troubleshoot common issues independently

Proposed Solutions

1. Expand "From Idea to Production" Runbook

   • Add detailed step-by-step procedures for each phase
   • Include validation steps for each phase
   • Add troubleshooting guidance for common issues
   • Include estimated timelines for each phase

2. Link to Detailed Procedures

   • Link to Vault setup documentation (issue #28192 (moved))
   • Link to helmfile/infra-mgmt onboarding documentation (issue #28193 (moved))
   • Link to observability setup procedures
   • Link to metrics catalogue procedures
   • Link to naming conventions guidelines

3. Add Examples and Templates

   • Provide example configuration files
   • Include templates for common tasks
   • Link to real-world examples from completed projects
   • Show before/after examples of configuration changes

4. Add Validation Checklists

   • Create checklists for each phase
   • Include validation steps to confirm completion
   • Provide commands or procedures to verify success
   • Include expected outputs or results

5. Document Common Issues and Solutions

   • Create a troubleshooting section
   • Document common issues encountered during pilot
   • Provide solutions for each issue
   • Include how to escalate to SREs if needed

6. Verify Accuracy

   • Review all procedures with SREs and component owners
   • Test procedures with non-SRE teams
   • Update any outdated information
   • Confirm procedures reflect current processes

• Troubleshooting section covers common issues
• Examples and templates are provided for common tasks
• All procedures are verified as accurate and current
• Links to related documentation (Vault, helmfile, observability, metrics) are included
• Non-SRE teams can follow the handbook to complete the full process
• Handbook is reviewed and approved by SREs and component owners
• Handbook is discoverable and easy to navigate
