3. What is Lean?
– Waste ₊ Value
– Cost ₊ Quality
– Inventory ₊ Employee Knowledge
– Defects ₊ Employee Empowerment
– Supplies ₊ Organizational Agility
– Cycle times ₊ Capability

7. Lean Principle 1: Flow
GOAL: Improve Throughput time by reducing Work In Progress
(WIP) Inventory
Batch Single-Piece Flow
Processing Processing
 Don‘t start building all features simultanelusly in isolation and then
integrate
 Instead cut the software features in small implementable and usable
features – Build, Integrate, Test, Document completely

8. Pre and Final JIT Assembly Lines: Fishbone
Takt 1 Takt 3 Takt 4
Debugging in Rules
Takt 2

9. Lean Principle 2: Takt
Goal: Achieve consistent rhythm by leveling the work contents
to eliminate overproduction and waiting!
 Pick what you can fully finish!
 Shorter release cycles
 Staff the teams rightly (Cross Functional Team of 10 members)
 Align the takts in all related groups

10. Lean Principle 3: Pull
GOAL: Produce when the customer needs to avoid overproduction

11. Lean Principle 3: Pull
GOAL: Produce when the customer needs to avoid overproduction
 Customer defines the prioritized backlog/feature set
 Top priority items are pulled by the development teams
 Customer consumes the software and give feedback

12. Lean Principle 4: Zero Defect
GOAL: Fix issues in Products and Processes Immediately

13. Stop the Line in case of Issues: ANDON
 If the takt delivery is affected/endangered all development activities
are STOPPED for the affected projects.
 STOP for Dev Projects means, “no new feature development, instead
everybody works on corrections in Integration Codeline”
 STOPPED projects do “root cause deep dive” to prevent future faults

14. Solve the Root Cause: 5 Whys
The machine stopped
Why?
It overloaded and the
fuse blew Why?
The spindle drive isn’t
properly lubricated Why?
The oil pump isn’t
running properly Why?
The oil pump shaft
bearings are worn out Why?
Dirt has gotten into the
Take preventive measures to fix the root cause oil pump

19. Scrum and Lean – The Winning Pair
Lean provides the principles and mindset on the
overall process from define to delivery
Scrum provides great framework and
methodology of project execution
Both methodologies offer great models and tools
to focus on critical aspects
