# Best Practices

TraceRTM best practices guide you through proven approaches for requirements management, test coverage, traceability, team collaboration, and project documentation.

## Why Best Practices Matter

### Quality Outcomes

Following best practices leads to:

- **Fewer defects**: Clear requirements reduce misunderstandings
- **Better coverage**: Systematic traceability identifies gaps
- **Faster audits**: Well-organized artifacts simplify compliance
- **Team alignment**: Consistent processes reduce friction

### Industry Standards

These practices align with:

- **DO-178C**: Aviation software safety
- **ISO 26262**: Automotive functional safety
- **IEC 62304**: Medical device software
- **ISO 29148**: Requirements engineering

## Best Practice Categories

### Requirement Writing

Write clear, testable, traceable requirements:

```python
from tracertm import TraceRTMClient

client = TraceRTMClient()

# Good: Clear, testable, atomic requirement
feature = client.create_item(
    title="User Login",
    item_type="feature",
    description="""
    Users shall be able to authenticate using email and password.

    Acceptance Criteria:
    - Valid credentials grant access
    - Invalid credentials show error message
    - Account lockout after 5 failed attempts
    - Session timeout after 30 minutes of inactivity

    metadata={
        "testable": True,
        "verifiable": True,
        "priority": "high"
    }
)
```

### Test Management

Organize tests for maximum coverage and efficiency:

```python
# Create test linked to requirement
test = client.create_item(
    title="Verify valid login credentials",
    item_type="test",
    description="Test successful authentication with valid email/password",
    metadata={
        "test_type": "functional",
        "automation": "automated",
        "priority": "high"
    }
)

# Link test to requirement
client.create_link(test.id, feature.id, "tests")

# Check coverage
coverage = client.get_coverage(feature.id)
print(f"Feature coverage: {coverage.percentage}%")
```

### Traceability

Maintain bidirectional links throughout the project:

```python
# Forward trace: requirement → implementation
client.create_link(code.id, feature.id, "implements")

# Backward trace: test → requirement
client.create_link(test.id, feature.id, "verifies")

# Impact analysis
impact = client.get_impact(feature.id)
for item in impact.affected:
    print(f"Change affects: {item.id} ({item.item_type})")
```

### Team Collaboration

Enable effective multi-team work:

```python
# Assign ownership
client.update_item(
    feature.id,
    metadata={
        "owner": "alice@example.com",
        "reviewers": ["bob@example.com", "carol@example.com"],
        "team": "authentication"
    }
)

# Track changes
history = client.get_history(feature.id)
for entry in history[-5:]:
    print(f"{entry.timestamp}: {entry.user} - {entry.action}")
```

### Documentation

Keep artifacts well-documented and discoverable:

```python
# Rich documentation with metadata
doc = client.create_item(
    title="Authentication System Design",
    item_type="design",
    description="""
    # Overview
    This document describes the authentication system architecture.

    ## Components
    - Login service
    - Session manager
    - Token validator

    ## Security Considerations
    - Password hashing with bcrypt
    - JWT tokens with 1-hour expiry
    - Rate limiting on login attempts
    """,
    metadata={
        "doc_type": "technical",
        "audience": ["developers", "security"],
        "review_status": "approved"
    }
)

# Link documentation to features
client.create_link(doc.id, feature.id, "documents")
```

### Version Control

Manage changes with proper versioning:

```python
# Create baseline for release
baseline = client.create_baseline(
    name="v1.0.0",
    description="Initial production release",
    include_types=["feature", "test", "design"]
)

# Compare baselines
diff = client.compare_baselines("v0.9.0", "v1.0.0")
print(f"Added: {len(diff.added)}, Modified: {len(diff.modified)}")
```

## Quick Reference

### Essential Practices

| Practice | Key Action | Benefit |
|----------|------------|---------|
| Atomic requirements | One requirement = one testable behavior | Clear test mapping |
| Bidirectional links | Forward and backward traceability | Full coverage visibility |
| Continuous updates | Link when creating, not later | Accurate traceability |
| Impact analysis | Check before changing | Prevent regressions |
| Regular audits | Weekly gap analysis | Early problem detection |

### CLI Commands

```bash
# Validate traceability rules
tracertm validate --rules required-links

# Check coverage gaps
tracertm coverage --min 80 --show-gaps

# Generate compliance report
tracertm report compliance --standard ISO26262 --output report.pdf

# Audit traceability quality
tracertm audit --since "30 days ago" --output audit.html
```

## Getting Started

1. **Assess current state**: Run `tracertm audit` to identify gaps
2. **Define standards**: Create `.tracertm/rules.yaml` with requirements
3. **Train team**: Share best practices documentation
4. **Automate validation**: Add checks to CI/CD pipeline
5. **Review regularly**: Schedule weekly traceability reviews
