Saving Big Blue

“I don’t know what ‘platform support’ is, but let me answer your question very simply. If there is a key customer requirement, do it. Whatever this thing is - ‘platform whatever’ - get it out of the way.”

Measure – Gather Data

Analyze – Root Cause Data Analysis

Improve – Develop Solutions

Control – Maintain the Gain

• Six sigma provides a systematic, logical approach to project management.

-Document-Response plan-Control Charts- Institution-alize

-Develop solutions-Select best solution-Pilot & Measure-Implement full scale

-Analyze data & process-Use graphical & statistics to verify root cause(s)

-ID key measures-Collect baseline data-Validate scope

What is Lean?What is Lean?

• A process improvement methodology• Based on principles developed at Toyota in the

50’s• Focuses on reducing cycle time by:

• Reducing the seven wastes• Using the “lean toolbox”

Six Sigma and Lean – Six Sigma and Lean –

How They’re SimilarHow They’re Similar

• Both methodologies:• Emphasize focusing on the

customer• Involve empowering

employees• Stress continuous

improvement• Use basic “quality tools”

Six Sigma and Lean –Six Sigma and Lean –

How They’re DifferentHow They’re Different

Six Sigma:• Focuses on defect

reduction• Emphasizes analysis• Is process focused Relies

heavily on statistics• Emphasizes

implementation infrastructure

• Is more client-centric

Lean:• Focuses on cycle time

reduction• Emphasizes solutions• Is value stream focused• Is more consultant

driven• Tends to be

implemented in phases by tool

Value - Add ActivitiesValue - Add Activities

The answer to all 4 questions must be yes for a step to be value-add.

• Does the customer care?

• Does it change the thing?

• Is it done right the first time? • Is it required by law or regulation
