Technical Leadership Best Practices
Technical leadership requires balancing hands-on technical work with strategic thinking, mentorship, and communication. GitScrum provides visibility that helps tech leads understand team workload, identify blockers, and ensure technical direction aligns with business priorities. Great tech leads multiply their impact through others rather than trying to write all the code themselves.
Tech Lead Responsibilities
| Area | Responsibilities | Time % |
|---|---|---|
| Technical | Architecture, code quality, decisions | 30-40% |
| Execution | Unblocking, delivery, planning | 20-30% |
| People | Mentoring, growing the team | 20-25% |
| Communication | Stakeholders, coordination | 15-20% |
Technical Direction
SETTING TECHNICAL DIRECTION
ARCHITECTURE DECISIONS:
┌─────────────────────────────────────────────────┐
│ As tech lead, you: │
│ ├── Propose architectural direction │
│ ├── Gather team input │
│ ├── Evaluate trade-offs │
│ ├── Make decisions (not defer forever) │
│ ├── Document rationale (ADRs) │
│ └── Own outcomes (good or bad) │
└─────────────────────────────────────────────────┘
DECISION FRAMEWORK:
┌─────────────────────────────────────────────────┐
│ Before deciding: │
│ ├── What problem are we solving? │
│ ├── What are the options? │
│ ├── What are the trade-offs? │
│ ├── What's reversible vs one-way door? │
│ ├── What does the team think? │
│ └── What's the long-term impact? │
│ │
│ Two-way doors: Decide quickly, can reverse │
│ One-way doors: Decide carefully, hard to undo │
└─────────────────────────────────────────────────┘
ADR (ARCHITECTURE DECISION RECORD):
┌─────────────────────────────────────────────────┐
│ Title: ADR-003: Use PostgreSQL for Primary DB │
│ Date: 2025-03-15 │

│ │
│ Context: │
│ We need a primary database for the new service.│
│ │
│ Decision: │
│ Use PostgreSQL on AWS RDS. │
│ │
│ Options Considered: │
