Case Studies

From weekly to daily releases

A DevOps transformation that enabled daily deployments while maintaining quality and reducing incidents.

Problem

A product team was stuck on weekly releases. Deployments were risky, incidents frequent, and the team couldn't respond quickly to user feedback.

DETA™ Approach

We applied DETA™ principles systematically:

  1. Golden paths: Created standard deployment templates
  2. Progressive delivery: Implemented feature flags and canary releases
  3. Comprehensive testing: Automated tests at every stage
  4. Monitoring: Real-time dashboards and alerting

Solution

  • Built CI/CD pipelines with automated testing and security scans
  • Introduced feature flags for safe experimentation
  • Set up canary deployments to reduce risk
  • Created comprehensive runbooks and monitoring

Outcomes

  • Deploy frequency: Weekly → Daily (7x increase)
  • Change-failure rate: 15% → 3% (80% reduction)
  • Time to restore: 2 hours → 20 minutes (83% reduction)
  • Incident count: 4/month → 0.5/month
