  9. 9. Advantages and disadvantages 9  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. 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. 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 11
