3. What is Six Sigma ? What is Sigma? • Sigma (s) is the Greek symbol used to represent standard deviation, a measure of the variation from the mean in a normal distribution • Six Sigma (6 ) is a business-driven, management philosophy based on multi-faceted approach to process improvement, reduced costs, and increased profits. It was pioneered by Motorola in 1986. CSE 577b - Six Sigma

4. Six Sigma methodologies • DMAIC • DMADV CSE 577b - Six Sigma

5. Process Improvement — DMAIC • Define: Define the project goals and customer (internal and external) deliverables • Measure: Measure the process to determine current performance • Analyze: Analyze and determine the root cause(s) of the defects • Improve: Improve the process by eliminating defects • Control: Control future process performance CSE 577b - Six Sigma

6. Define – Measure – Analyze – Design – Verify (DMADV) • Define: Define the project goals and customer (internal and external) deliverables • Measure: Measure and determine customer needs and specifications • Analyze: Analyze the process options to meet the customer needs • Design: Design (detailed) the process to meet the customer needs • Verify: Verify the design performance and ability to meet customer needs CSE 577b - Six Sigma

7. Six Sigma Key Roles • Executive Leadership • Champions • Master Black Belts • Black Belts • Green Belts CSE 577b - Six Sigma

8. A Typical Six Sigma Project in Software • Customers express concern that software defects are causing frequent failures in the field • A Six Sigma team is formed to scope the problem, collect data, and determine the root causes • The team’s analysis of the data determines that poorly understood interface requirements accounts for 90% of the problem in the field • The project collects data to verify the problem has been corrected, and continues collecting data to ensure the problem does not return • The organization’s requirements process is modified to ensure future projects do not encounter similar problems CSE 577b - Six Sigma

9. How Six Sigma Helps Process Improvement • PI efforts often generate have little direct impact on the business goals • Six Sigma delivers results that matter to managers (fewer defects, higher efficiency, cost savings, etc …) • Six Sigma concentrates on problem solving in small groups, focused on a narrow issue • Six Sigma focuses on the customer’s perception of quality CSE 577b - Six Sigma
