Critical Evaluation of Lean Six Sigma

Comparing Waterfall, Agile, and Lean Six Sigma

Waterfall

• Project focused• Fixed phases and linear timelines• Fixed requirements• Teams with clearly set goals and timelines

Agile

• Project focused• Short-termed delivery cycles• Agile requirements• Customer involvement• Empowered teams

Lean Six Sigma

• Process focused• Removes non-value added process steps• Reduces variation and improves quality• Speed + accuracy

Combining Lean Six Sigma and Waterfall or Agile

Lean Six Sigma and waterfall

• 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 agile

• 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’
