Implementation Guidance
Phased Delivery
| Stage | Timeline | Focus |
|---|---|---|
| MVP | 2-4 weeks | Core workflow only, simplest architecture, manual processes OK. Validate problem-solution fit. |
| Beta | 4-8 weeks | Key features, basic scalability, monitoring, automated deployment. Validate product-market fit. |
| Production | 8-12 weeks | Full features, production-grade reliability, auto-scaling, DR. Scale and optimize. |
| Optimization | Ongoing | Performance tuning, cost optimization, feature refinement. Efficiency and experience. |
Critical Path Analysis
For each stage identify:
- Blocking dependencies: What must be done first?
- Parallel workstreams: What can happen simultaneously?
- Resource constraints: Who's needed, when?
- Risk areas: What might delay us?
- Decision points: What decisions can't be delayed?
Observability Stack
Metrics (quantitative health)
- Business metrics (signups, transactions, revenue)
- System metrics (CPU, memory, disk, network)
- Application metrics (request rate, latency, errors)
Logging (what happened)
- Structured JSON logs
- Correlation IDs across services
- Context (user ID, request ID, session)
- Appropriate levels: ERROR actionable, WARN concerning, INFO key events
Tracing (where time spent)
- Distributed traces with OpenTelemetry
- Critical path instrumentation
- Database query timing
- External API call timing
Alerting (what needs attention)
- SLO-based alerts (error rate, latency, availability)
- Actionable only (if it fires, someone must do something)
- Runbooks for each alert
- Escalation policies
