Adaptive Cadence

Ship when ready. Feature flags, CI, and tests replace calendar-driven delivery.

Beyond Time-Boxed Releases

Traditional software development follows fixed release schedules:

Sprint ends → Release happens
Features ready or not, the calendar decides
Incomplete work gets rushed or punted
Quality suffers under deadline pressure
Teams optimize for dates, not value

The RAD Alternative: Ship continuously when features are truly ready, not when the calendar says so.

The Problem with Calendar-Driven Delivery

Artificial Deadlines Create Waste

When releases happen on fixed dates:

Last-minute scrambling - “We have to ship by Friday!”
Cut corners - Skipping tests to meet deadlines
Feature bloat - Forcing partial features into releases
Burnout - Crunch time every sprint end
Delay costs - Waiting weeks for next release window

Example:

Traditional 2-Week Sprint:

Day 1-8:   Normal development pace
Day 9-11:  Scramble to finish "committed" work
Day 12:    Code freeze, stabilization panic
Day 13:    Sprint review (demo half-finished features)
Day 14:    Sprint retro + planning for next sprint

Result: Stressed team, uneven quality, artificial urgency

Continuous Delivery in RAD

RAD embraces adaptive cadence—shipping when features are ready:

Core Enablers:

Feature Flags - Deploy code without exposing features
Continuous Integration - Automated testing on every commit
Automated Testing - Comprehensive test coverage
Monitoring & Telemetry - Real-time production insights
Rollback Capabilities - Quick recovery from issues

The result: Deploy daily, release strategically.

How It Works: Feature Flags

Feature flags decouple deployment from release:

Deploy Dark

// Code deployed to production but not visible
if (featureFlags.isEnabled('new-checkout-flow')) {
  return <NewCheckoutFlow />;
} else {
  return <OldCheckoutFlow />;
}

Gradual Rollout

New Checkout Flow Rollout:

Day 1: Enable for internal team (10 users)
- Monitor: Error rates, performance, feedback

Day 2: Enable for beta users (100 users)
- Monitor: Conversion rate, user behavior

Day 5: Enable for 10% of users (1,000 users)
- Monitor: A/B test results, metrics comparison

Day 10: Enable for 50% of users (5,000 users)
- Confirm: No regressions, positive metrics

Day 15: Enable for 100% of users (10,000 users)
- Decision: Full rollout or adjust based on data

Quick Rollback

Issue Detected: Payment processing error spike

Action: Disable feature flag "new-checkout-flow"
Time to rollback: 30 seconds
Impact: Zero downtime, users revert to stable version

vs. Traditional Release:
Time to rollback: 2-4 hours (redeploy previous version)
Impact: Extended downtime, customer complaints

Continuous Integration & Testing

Every code change goes through automated validation:

CI Pipeline (Every Commit)

Commit pushed to GitHub
     ↓
1. Automated tests run (30 seconds)
   - Unit tests
   - Integration tests
   - Linting and type checking
     ↓
2. Build & compilation (1 minute)
   - Create production bundle
   - Optimize assets
     ↓
3. Deploy to staging (2 minutes)
   - Automatic deployment
   - Smoke tests run
     ↓
4. Ready for production (manual or automated)
   - One-click deployment
   - Feature flag controlled

Total time: ~4 minutes from commit to staging

Test Coverage Requirements

Quality Gates (Enforced by CI):

✅ Unit test coverage: >80%
✅ Integration tests: All critical paths
✅ No linting errors
✅ Type safety: 100%
✅ Security scan: No high/critical issues
✅ Performance: No regressions >5%

If any gate fails: Deployment blocked

Ship When Ready, Not When Scheduled

Features ship based on readiness, not calendar:

Readiness Criteria

Criterion	How We Verify
Functionality	All acceptance criteria met and tested
Quality	Tests pass, code reviewed, no known bugs
Performance	Load tested, meets SLA requirements
Security	Vulnerability scan passed, security review complete
Documentation	User docs written, API docs updated
Monitoring	Telemetry in place, alerts configured
Rollback Plan	Feature flag or rollback procedure defined

Example: Feature Release Timeline

"Mobile Push Notifications" Feature:

Jan 5:  Development started
Jan 12: Code complete, deployed to staging (feature flag OFF)
Jan 15: QA testing in staging environment
Jan 17: Found edge case bug, fix deployed
Jan 19: QA sign-off, ready for production
Jan 20: Deployed to production (feature flag OFF)
Jan 21: Enabled for internal team (20 users)
Jan 23: Enabled for 5% of users (500 users)
Jan 26: Monitoring shows great metrics
Jan 27: Enabled for 100% of users (10,000 users)

Total: 22 days from start to full release
Actual "release" spread over 7 days
Zero customer impact from issues

Multiple Cadences Coexist

Different types of work have different cadences:

Fast: Hotfixes & Bug Fixes

Critical bug reported → Fixed → Tested → Deployed
Timeline: Hours (same day)

Process:
- Fix developed and tested
- Reviewed by one other developer
- Deployed directly to production
- Monitored closely for 24 hours

Medium: Features

Feature developed → Staged → Tested → Gradual rollout
Timeline: Days to weeks

Process:
- Developed with feature flag
- Comprehensive testing in staging
- Gradual production rollout
- Monitor metrics and feedback
- Full rollout when validated

Slow: Architectural Changes

Architecture change → Tested → Validated → Migrated
Timeline: Weeks to months

Process:
- Extensive design and review
- Parallel systems during migration
- Comprehensive testing
- Incremental migration
- Decommission old system when safe

Real-World Benefits

Faster Time to Value

Traditional Approach:
- Feature ready on Day 8 of 14-day sprint
- Waits until Day 14 to ship
- Lost value: 6 days

RAD Approach:
- Feature ready on Day 8
- Deployed to production Day 8 (flag OFF)
- Enabled for users Day 9
- Lost value: 1 day

Reduced Risk

Traditional Big Release:
- 20 features ship simultaneously
- If issue found, hard to identify cause
- Rollback requires redeploying entire release

RAD Continuous Release:
- Features ship independently when ready
- Issues isolated to specific feature
- Rollback via feature flag (instant)

Better Work-Life Balance

Traditional End-of-Sprint Crunch:
- Late nights to meet Friday deadline
- Weekend work to stabilize release
- Stressful "feature freeze" period

RAD Flow:
- Steady pace throughout
- Ship when truly ready
- No artificial urgency

Best Practices for Adaptive Cadence

1. Invest in Automation

Make deployment painless:

Comprehensive automated testing
CI/CD pipelines for all projects
Infrastructure as code
Automated rollback procedures

2. Use Feature Flags Liberally

Don’t wait for “special cases”:

Flag all new features by default
Keep flags simple and well-documented
Clean up old flags regularly
Use flags for gradual rollouts

3. Monitor Everything

You can only ship fast if you know things work:

Application performance monitoring
Error tracking and alerting
User behavior analytics
Business metrics dashboards

4. Build Rollback Confidence

Practice makes perfect:

Test rollback procedures regularly
Document rollback steps
Use feature flags for instant rollback
Maintain deployment history

5. Shift Quality Left

Catch issues early:

Write tests as you code
Run tests on every commit
Code review before merge
Staging environment validation

The Freedom of Continuous Delivery

When you can ship any time, you gain:

Flexibility - Respond to urgent needs immediately
Confidence - Small changes are less risky
Speed - Value reaches users faster
Quality - No pressure to cut corners for deadlines
Innovation - Experiment without fear

The RAD Promise: Ship daily, release strategically, sleep soundly.
