Six Sigma Black Belt Study Guide
What's Contained on the Charter? - answer Problem Description, Scope, Project Goals,
Customer Benefits, Ownership/Team, Stakeholder Approval, Schedule
What are the Three Pillars of PE? - answer Lean, DMAIIC, DMADV
What is used to set Specification Limits? - answer Customer requirements
What is the difference between an Activity Flowchart and a Deployment Flowchart? -
answerActivity Flowchart: displays complexity & decision points in a process done by 1
person.
Deployment Flowchart: highlights handoff areas in processes between people or
functions. Clarifies roles and dependencies.
Describe the 5 Phases of the Roadmap and list the purpose of each and the likely
outcome or deliverables from each phase. - answerDefine: Business case/problem to
be addressed and how, Measure: Establish a baseline, Analyze: Identify root cause and
confirm with data, Improve/Innovate: Develop & implement solutions,
Control: Maintain the gains by standardizing processes for on-going improvement.
What is Market Segmentation? - answerMarketing strategy that divides broad target
market into subsets that have common needs and priorities.
What's the difference between proactive and reactive VOC? - answerReactive:
Information comes to you whether you take it or not (complaints, returns).
Proactive: Self-initiated to gather information (market research, customer interviews,
surveys).
CTQ's are derived from what? - answerCustomer specifications/requirements used to
create a CTQ tree to translate broad requirements into specific requirements.
VOC.
What's a Stakeholder's Analysis? - answerIdentification of individuals/groups that affect
or are affected by a proposed action, and sorting them according to their impact on the
action and the impact the action will have on them.
What's the difference between a SIPOC and a Process Flow Map? - answerA SIPOC is
high level process map which takes suppliers, inputs, outputs, and customers into
account. A Process Flow Map is detailed flow diagram of the process that drills further
detail.
, What's an Affinity Diagram? - answerA tool that gathers large amounts of language data
(ideas, opinions, issues) and organizes them into groups based on their natural
relationships. Often used to group ideas generated by brainstorming.
What do Lean Principles focus on? - answerEliminating waste
Why do we need a Charter? - answerClarify expectations of team, Keep team aligned
with organization, Keep team within scope- "scope creep", Gives authorization to work
on project
What's the Kano Model? - answerMethod of obtaining VOC. It charts customer
satisfaction vs presence of a characteristic or other item.
What's the filter for evaluating proper Process Excellence project? - answerOO'SMART
(owned by you, output, specific, measurable, attainable, relevant, time-bound)
What's Six Sigma? - answerMethodology used to attack process variability in order to
eliminate defects. Ruthless/relentless identification and elimination of sources of
variation for positive business impact.
What are the objectives during the Define Phase? - answerDevelop the business case,
scope, and charter
How do I calculate Sigma? - answerMethod 1 is DPMO
Method 2 is using standard deviation and spec limits
Which tool is best used to illustrate X's in a process? - answerFishbone diagram (cause
and effect, Ishikawa)
What are considered Funneling Tools for X's up front? - answerFishbone diagram
(cause and effect, Ishikawa)
What are the 6 Sources of Variation? - answer1. Within Unit- Different measurements at
different points on same part
2. Unit to Unit- One part to the next
3. Sub Group to Sub group
4. Stream to Stream- Supplier to supplier, line to line, machine to machine
5. Time- Short term to long term
6. Measurement- Gage R&R
What are the 4 Capability Indices and what do they tell you? - answerCp/Cpk: Process
Potential
Pp/Ppk: Current Performance
What's the difference between Cp and Pp? What's the difference between Cp and Cpk?
- answerCp: measures potential process capability against specification
