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
