2. 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
• Coverage , have we done enough?
• Impediments and remove the blockings.

3. Change our thinking process?

4. Think Beyond
• See the whole.
• Focus only on value
adding activities
• Constant customer
Value generation

5. How can we help Stream to flow and flow….
• Constantly optimize
the flow , remove
the impediments
from the system
• Make several tasks
parallel and do
constant handshake

6. Value generation model

7. What did we do to reduce the cycle time?

8. Empowered Team to take action

9. Gamifying work: -How we have implemented
Fun, play and work

10. Requirement Engineering: Are we solving the right puzzle ?

11. Expectation from Our Lean test engineers

12. Impact Based Testing to reduce regression
cycle time
• Where are the most changes? get the
data from code churn report?
• Assess the areas impacted and
functionalities?
• Concentrate testing towards that area

13. Quality Coverage: Have we done enough?

14. Dashboard: Are we able to see everything ?

15. Common Impediments and
Mitigation

16. Key Takeaway
