LEAN SIX SIGMA GREEN BELT
CERTIFICATION EXAM QUESTIONS
WITH VERIFIED ANSWERS
\.What is Six Sigma? - ANSWERS-is both a methodology for process improvement
and a statistical concept that seeks to define the variation inherent in any process.
\.The overarching premise of Six Sigma - ANSWERS-is that variation in a process
leads to opportunities for error; opportunities for error then lead to risks for
product defects.
\.Decision-making with Six Sigma - ANSWERS-The six sigma method lets
organizations identify problems, validate assumptions, brainstorm solutions, and
plan for implementation to avoid unintended consequences.
\.What is 6σ as a statistical concept? - ANSWERS-is a statistical representation of
what many experts call a "perfect" process. Technically, in a six sigma process,
there are only 3.4 defects/1,000,000 opportunities, or 99.99966% of the products
from six sigma are without defect.
\.Common six sigma principles - ANSWERS-- Customer-focused improvement
- Value streams
- Continuous process improvement
- Variation
,- Removing waste
- Equipping people
- Controlling the process
\.Value stream - ANSWERS-is the sequence of all items, events, and people
required to produce an end result
\.Jidoka - ANSWERS-a principle that creates control of defects inside a business.
Jidoka demands that a process stop as soon as errors are detected instead of
identifying defects at the end of the production line and attempting to trace errors
back to a source.
\.Principles of Lean Six Sigma - ANSWERS-- Defining customer values
- Identifying the value stream for customer needs and desires
- Identifying waste in the process
- Creation of a continuous process flow
- Continually working to reduce the number of steps and time it takes to reach
customer satisfaction
\.Rummler-Brache's Nine Box Model - ANSWERS-- Improvement-planning
- Definition
- Analysis and Design
- Implementation
- Management of process
- Processes are turned over to daily teams
, \.Scrum - ANSWERS-is a project development method specific to Agile
programming endeavors in technical departments.
\.When to use six sigma - ANSWERS-- When facing the unknown
- When problems are widespread and not defined
- When solving complex problems
- When costs are closely tied to processes
\.Other formal quality or process improvement programs - ANSWERS-- Lean
Process Management
- Total Quality Management
- Business Process Reengineering
- Rummler-Brache
- Scrum
- The Customer Experience Management Method
- JumpStart
\.Muda - ANSWERS-Waste that fails to add value to a product or process as
defined by the customer or end-user.
\.The Seven Muda or Wastes - ANSWERS-- Overproduction
- Correction
- Inventory
