Abstract: • Is our test team doing the right work ?
• How can we achieve below target?
• Reduce cycle time from 15 months production to release cycle to 10 months
• Improve Defect removal efficiency from 75% to greater than 90%
• Reduce regression cycle time by 50%
• What we have done?
• Lean Mindset and Think Beyond
• Flow optimization and Cycle time reduction steps
• Empowered team
• Requirement Engineering
• Increase engagement through gamification
• Risks based test strategy
• Team dashboard

Change our thinking process?
Think Beyond
• See the whole.• Focus only on value
adding activities• Constant customer
Value generation
How can we help Stream to flow and flow….
• Constantly optimizethe flow , removethe impedimentsfrom the system
• Make several tasksparallel and doconstant handshake
Value generation model
What did we do to reduce the cycle time?
Empowered Team to take action
Gamifying work: -How we have implemented Fun, play and work
Requirement Engineering: Are we solving the right puzzle ?
Expectation from Our Lean test engineers
Impact Based Testing to reduce regression cycle time
• Where are the most changes? get thedata from code churn report?
• Assess the areas impacted andfunctionalities?
• Concentrate testing towards that area
Quality Coverage: Have we done enough?
Dashboard: Are we able to see everything ?
Common Impediments and Mitigation
