# 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
