3. What is Lean
Lean consists of proven
tools and techniques that
focus on minimizing wasteful
activity and adding value to
the end product to meet
customer needs.

9. Advantages and disadvantages

 Advantages :
 Decreasing waste
 Increases business efficiencies – make sure staff
time is spent on value‐added activities.
 Using empirical methods to decide what matters , rather then
uncritically accepting pre-existing ideas
 Simplify processes
 Save money – reduce overhead in paperwork

10. Advantages and disadvantages
10
 Disadvantages:
 Strong customer relationships
 Success in the software development depends on how disciplined the
team members are and how advance their technical skills.
 The role of a business analyst is vital to ensure the business
requirements documentation is understood properly. If any organization
don't have a person with the right business analyst then this method
may not be useful for them.
 In this development model great flexibility is given to developer which is
surely great, but too much of it will quickly lead to a development team
who lost focus on its original objectives thus, it heart the flow of entire
project development work.

11. Conclusion
There are 7 Principles and 22 Tools.
The main goal of Lean Software Development are
 Elimination of waste
 Improve:
 Productivity
 Efficiency
 Bottom line
