6. Comparing Waterfall, Agile, and Lean Six Sigma
•Project focused
•Fixed phases and linear timelines
•Fixed requirements
•Teams with clearly set goals and timelines
Waterfall
•Project focused
•Short-termed delivery cycles
•Agile requirements
•Customer involvement
•Empowered teams
Agile
•Process focused
•Removes non-value added process steps
•Reduces variation and improves quality
•Speed + accuracy

7. Combining Lean Six Sigma and Waterfall or Agile
• Lean six sigma projects:
• Determine which problems projects should address
• Determine broad solutions
• Waterfall projects:
• Spawned in the ‘improve’ phase
• Further define solutions
• Establish process control
Lean Six Sigma and waterfall
• Possible models:
• Initial approach
• Lean six sigma facilitates rapid process definition and measurement exercises
• During each iteration, lean six sigma analyses process performance,
quantifies project value, facilitates feedback and backlog prioritisation, and
assists with operational integration
• Integrated approach
• Lean six sigma projects provide initial definition and analysis of process areas
• Agile projects are spawned on the ‘improve phase’
