BENEFITS• Process improvement and

redesign (manufacturing, construction, financial services, healthcare, public sector, high-tech industry)

• Resulting in superior quality and efficiency levels

• Structural financial impact

STRATEGIC VALUE• Superior cost structure• Competitive advantages based

on customer satisfaction• Competence development in

operations management, project management and continuous improvement

METHOD• Professional and scientific

problem solving• Working with precise and

quantitative problem descriptions• Starting with a data-based

diagnosis• Designing evidence-based

improvement actions

ORGANIZATION• Improvement projects are led by Green

and Black Belts, who are familiar with the process and Lean Six Sigma

• Improvement projects follow the DMAIC approach

• Lean Six Sigma program management coordinates projects by strategically choosing projects and making sure that benefits are realized

- Project charter- SIPOC and process flow chart- Benefit analysis- Organization (time and review board)- Stakeholder analysis

2. VALIDATE THE MEASUREMENTPROCEDURES

- Validity of the measurements: before, during and after data collection

- Precision: gage R&R or agreement study (kappa)- Pilot measurement- Start measuring

Check definitionsand calculations

Face validity

- CTQ flowdown- Operational definitions- Measurement plan and forms

5. ESTABLISH THE EFFECT OF INFLUENCE FACTORS

Process matrix

Statistical dataanalysis

- Select the most important influence factors- Determine impact and changeability of

influence factors- Summarize evidence
