White Belt Chapter 1: What is 6s?

Question 1

What is the principle of 6 sigma?

Answer 1

• a process methodology should be constant w/o variation.
• why? because variation-> leads to opportunities for error ->defects in product -> POOR CUSTOMER SATISFACTION (Customer’s voice)

Question 2

Data Driven Processes and Decisions. What Does that Mean?

Answer 2

Goal of a 6s operation is to base implemented strategies from data + metrics.

Provides mathematical + statistical foundation for decision making.

Question 3

Decision Making w/o 6S

Answer 3

Problem with making decisions w/o 6s is that it causes redundant issues.

Ex: Would be having to go back and fix other problems that were incurred after applying a strategy.

Question 4

Decision Making with Six Sigma

Answer 4

benefits:
-highly accurate when understanding the problem in a process

• understanding the root cause of a problem
• gives visualized and predicted outcomes less financial risk

Question 5

Defining 6 Sigma

Answer 5

6 sigma is statistical perfection:

• 3.4 defects per million units created
• as you go from 6-5-4-3 sigma levels
• the customer satisfaction decreases

Question 6

Calculating Sigma Level

Answer 6

Yield= (# of opportunities- #of defects)/ (# of opportunities)=
% Yield

That % Yield can be looked up to give a Sigma Level

Question 7

Sigma Level is Not a Final Indicator

Answer 7

When talking about improving a process- you need to look at multiple things together.

• Leadership should cover: (costs, resources, and estimated impact on improvements)
• Also understand the 80/20 Pareto Rule (multiple processes involved, which one is most important?)

Question 8

Common Six Sigma Principles

Answer 8

• Customer Focused Improvement
• understanding the process value stream (SIPOC)
• Continuous Process Improvement
• Removing Variation @ all processes
• Removing waste or “muda” (DOWN-TIME Acronym)

-Equipping People-
once a 6 sigma team understands the process and has implemented issue soln. They need to let business process owner know & also other employees.

• Controlling the Process
• once a process is fixed, employees need to know how to manage those processes with graphical/statistical data analysis (control charts) to maintain productivity/sigma level.

Question 9

Challenges of 6 Sigma

Answer 9

Some people don’t see the value of 6 sigma:

• lack of support
• lack of resources
• poor project execution
• data access issues
