Distributed platform engineering teams face coordination challenges absent from colocated teams. Platform work requires deep technical context, architectural alignment, and careful coordination across backend services, integration development, and infrastructure operations. Async-first communication principles enable distributed teams to maintain high velocity without synchronous meeting overhead.
Async-First Communication Principles
Platform engineering decisions require technical depth and thoughtful analysis. Synchronous meetings interrupt focus time required for complex systems design. Async communication enables engineers to respond with full context after investigating code, reviewing architecture diagrams, and considering tradeoffs.
When to Use Async Communication
Architecture Decisions: Document proposed architectures in written form with diagrams, tradeoffs analysis, and implementation timeline. Stakeholders review and comment async, enabling thoughtful feedback without meeting coordination.
Code Reviews: Pull requests provide async code review mechanism. Reviewers examine code, run tests, and provide detailed feedback on their timeline. Authors address feedback and iterate without scheduling synchronization meetings.
Technical Design Reviews: Post design documents to shared repository. Engineers review on their schedule, add inline comments, and propose alternatives. Final discussion occurs in focused meeting after everyone has reviewed async.
Integration Specifications: Document integration requirements, API specifications, and error handling in written format. Engineers implementing integrations reference documentation without requiring real-time meetings.
When Synchronous Communication is Required
Incident Response: Production incidents require real-time coordination. Use video calls for triage, investigation, and resolution.
Architectural Disagreements: When async discussion reveals fundamental disagreement, schedule synchronous meeting to resolve. Time-bound discussion (30 minutes) with clear decision framework.
Onboarding Sessions: New engineers benefit from real-time pairing sessions and architecture walkthroughs. Schedule focused sessions during onboarding period.
Team Building: Distributed teams require intentional social connection. Regular video socials maintain team cohesion.
Technical Design Documentation
Written design documents enable async collaboration on architectural decisions.
Design Document Structure
Problem Statement: Clear description of problem being solved. Include business context, technical constraints, and success criteria.
Proposed Solution: Detailed architecture with diagrams, component interactions, and data flow. Explain design decisions and justify technology choices.
Alternative Approaches: Document alternatives considered and reasons for rejection. Prevents recurring debates on settled decisions.
Implementation Plan: Break implementation into phases with dependencies. Estimate effort and identify risks.
Success Metrics: Define how to measure solution success. Include performance targets, reliability requirements, and adoption metrics.
Design Review Process
- Author drafts design: Engineer creates design document in shared repository (Google Docs, Notion, GitHub).
- Request review: Post document link in engineering channel with review deadline (72 hours).
- Async review: Reviewers examine document, add inline comments, and ask questions.
- Author responds: Address feedback, update document, and respond to questions.
- Approval: After addressing major concerns, reviewers approve design.
- Optional sync: For complex designs or unresolved debates, schedule 30-minute discussion.
Pull Request Best Practices
Code reviews are primary async collaboration mechanism for distributed engineering teams.
PR Size and Scope
Target: 200-400 lines changed: Large PRs slow review process and reduce review quality. Break large features into multiple PRs.
Single Concern: Each PR addresses one logical change. Mixing refactoring with feature work creates review confusion.
Self-Contained: PR should be independently reviewable without referencing external context. Include background in PR description.
PR Description Template
## What
Brief description of changes.
## Why
Business context or bug being fixed.
## How
Technical approach and implementation details.
## Testing
Test strategy and validation approach.
## Deployment
Deployment considerations, feature flags, or rollout plan.
## Screenshots
For UI changes, include before/after screenshots.
Review Response Time
Target: <8 hours during business hours: Blocked PRs slow team velocity. Reviewers prioritize PR reviews to unblock authors.
Use Draft PRs: Mark PRs as draft for early feedback or work-in-progress. Prevents premature review when code isn't ready.
Request Specific Reviewers: Tag engineers with relevant expertise rather than broadcasting to entire team.
Architecture Decision Records (ADRs)
ADRs document architectural decisions with context and rationale. Distributed teams benefit from searchable decision history.
ADR Structure
Title: Concise decision description (e.g., "Use PostgreSQL JSONB for workflow state").
Status: Proposed, Accepted, Deprecated, or Superseded.
Context: Problem being solved, constraints, and forces influencing decision.
Decision: Chosen approach with technical details.
Consequences: Positive and negative outcomes from decision. Include maintenance burden, performance implications, and technical debt.
ADR Workflow
- Draft ADR: Engineer proposes decision in new ADR document.
- Team Review: Share ADR in engineering channel for review.
- Discussion: Engineers comment on ADR, suggesting alternatives or identifying concerns.
- Decision: After review period (3-5 days), mark ADR as Accepted or revise based on feedback.
- Archive: Store ADRs in version-controlled repository for future reference.
Integration Development Coordination
Integration work spans multiple engineers: platform team builds connector framework, integration team implements specific connectors, and infrastructure team deploys and monitors.
Integration Request Process
Customer Request: Sales or customer success team identifies integration need.
Prioritization: Product team evaluates integration against prioritization framework (customer demand, market differentiation, technical complexity).
Specification: Integration team documents API analysis, authentication requirements, rate limits, and error scenarios.
Implementation: Platform team assigns integration to engineer. Engineer develops connector, writes tests, and documents usage.
Review: Platform team reviews implementation for security, error handling, and code quality.
Deployment: Infrastructure team deploys integration to staging for validation, then production.
Monitoring: Platform team monitors integration error rates and performance for first week.
Integration Documentation
Each integration requires comprehensive documentation:
- API Analysis: Endpoints used, authentication method, rate limits
- Configuration Guide: How users connect integration
- Action Documentation: Available actions, parameters, and response formats
- Error Handling: Common errors and resolution steps
- Testing Guide: How to test integration functionality
Incident Response Playbooks
Distributed teams require documented procedures for incident response.
Incident Severity Levels
Severity 1 (Critical): Platform outage affecting all customers. Page on-call engineer immediately.
Severity 2 (High): Integration degradation or workflow execution failures affecting subset of customers. Alert on-call engineer via Slack.
Severity 3 (Medium): Performance degradation without customer impact. Create ticket for investigation.
Incident Response Process
- Detection: Monitoring alerts detect anomaly and create incident.
- Triage: On-call engineer assesses severity and impact.
- Communication: Post incident update in status channel. Notify affected customers if severity 1 or 2.
- Investigation: Debug issue using logs, metrics, and distributed traces.
- Mitigation: Implement fix or rollback to restore service.
- Resolution: Verify metrics return to normal. Close incident.
- Postmortem: Within 48 hours, write postmortem documenting timeline, root cause, and prevention measures.
Postmortem Template
## Incident Summary
