Free Certified Six Sigma Black Belt MCQ Questions and Answers — Questions and Answers

Question 1: In terms of waste identification, which of the following is/are not key concepts in the Toyota Production System (TPS)?

Muri
Maru (Correct answer)
Mura
Muda

Correct answer: Maru

The Toyota Production System (TPS) identifies three main types of waste, often referred to as the '3 Ms': Muda (wasteful activities), Mura (unevenness or inconsistency), and Muri (overburden or unreasonableness). 'Maru' is not a recognized term for waste within the TPS framework. Understanding these three types of waste is crucial for Lean practitioners.

Question 2: Which of the following should be done after establishing ownership?

Define the mission, or purpose, of the process. (Correct answer)
Identify the process of business.
Establish main financial assets.
All of the above

Correct answer: Define the mission, or purpose, of the process.

After establishing clear ownership for a process, the logical next step in effective process management is to define its mission or purpose. This step ensures that all stakeholders understand the process's objectives and its contribution to the overall organizational goals. A well-defined mission provides direction and a basis for measuring success and identifying improvement opportunities.

Question 3: Which of the following claims about the Process Improvement Team (PIT) is/are correct?

They are made up of lower-level managers.
They conduct ongoing activities to ensure process effectiveness, efficiency, and adaptability.
They establish the basics of process quality management.
They are process functional owners. (Correct answer)

Correct answer: They are process functional owners.

Process Improvement Teams (PITs) are typically comprised of individuals who are directly involved in, or have deep expertise in, the process under review. They often represent the functional owners or key stakeholders of different parts of the process. Their role is to analyze, recommend, and implement improvements, leveraging their intimate knowledge and ownership of the process functions.

Question 4: Which of the following is NOT a Process Management Committee characteristic?

All process activities are represented.
Conduct ongoing activities to ensure process effectiveness, efficiency, and adaptability. (Correct answer)
The senior/top manager of the parent function for each activity is a member.
The members are peer level, to the degree possible.

Correct answer: Conduct ongoing activities to ensure process effectiveness, efficiency, and adaptability.

A Process Management Committee (PMC) is a high-level governance body responsible for strategic oversight and guidance of processes. While they set policies and monitor overall performance, the *ongoing activities* to ensure day-to-day process effectiveness, efficiency, and adaptability are typically carried out by process owners, operational teams, or Process Improvement Teams. The PMC's role is more strategic and less operational.

Question 5: Which of the following is a method for picking from bigger lists of alternatives? They can be used to choose an issue from a list of possible problems, major underlying causes from a wider list, or a remedy from a list of options.

Fundamental Lean Strategies
SWOT Analysis
Six Sigma Measurements
Matrix diagram (Correct answer)

Correct answer: Matrix diagram

A matrix diagram is a visual tool used to analyze and display the relationships between different sets of items, such as problems, causes, or solutions. It helps in systematically prioritizing and selecting from larger lists by illustrating the strength and type of connections between elements. This makes it highly effective for choosing key issues, underlying causes, or optimal remedies from a comprehensive list of alternatives.

Question 6: Which technique concentrates a group's attention on a single process for a 1- or 2-day meeting to outline how the group might enhance the process over the next 90 days?

Fast action solution technique (Correct answer)
Just-In-Time Modification
The 90 Days Cycle Time Function
Interpersonal Problem-Solving Technique

Correct answer: Fast action solution technique

The description perfectly matches a 'Fast Action Solution Technique,' often known as a Rapid Improvement Event or Kaizen Event. These are intensive, short-duration (typically 1-5 days) meetings involving key process participants, focused on quickly identifying and implementing solutions to specific process improvement areas within a defined timeframe, such as 90 days.

Question 7: The matrix diagram is a method for investigating relationships that is available in which of the following formats?

W-Shaped Matrix
M-Shaped Matrix
L-Shaped Matrix (Correct answer)
All of the above

Correct answer: L-Shaped Matrix

Matrix diagrams are versatile tools for investigating relationships and come in various formats depending on the number of groups being compared. The L-shaped matrix is the most common and fundamental type, used to show the relationships between two distinct groups of items. Other formats like T, Y, X, C, and R matrices exist for more complex comparisons.

Question 8: For Six Sigma to successfully affect change, _________ across the business is necessary.

Money
Buy-in (Correct answer)
Vendors
Executives

Correct answer: Buy-in

For Six Sigma initiatives to be successful and drive lasting change, widespread 'buy-in' or commitment from all levels of the organization is absolutely essential. Without the active support, understanding, and participation of employees, managers, and executives, projects can face resistance, lack resources, and ultimately fail to achieve their intended impact or be sustained.

Question 9: Standardize (also known as Seiketsu) is a technique for producing and delivering the appropriate goods in the appropriate quantities and at the proper times, locations, and places. The idea of a Pull system depends on this premise.

False (Correct answer)
True

Correct answer: False

The statement is false. Standardize (Seiketsu) is one of the 5S principles, focusing on maintaining cleanliness and order through standardized practices. The description provided, 'producing and delivering the appropriate goods in the appropriate quantities and at the proper times, locations, and places,' accurately defines the core concept of Just-in-Time (JIT) and a Pull system, not Seiketsu.

Question 10: Rapid Improvement Event (also known as a Kaizen Event): In actual practice, a Kaizen is a Rapid Improvement Event that typically lasts between one and five days and involves important process participants who concentrate on resolving a specifically defined area for process improvement.

False (Correct answer)
True

Correct answer: False

The statement is false because the description provided is actually a correct definition of a Rapid Improvement Event (Kaizen Event). Kaizen Events are indeed typically short-duration (1-5 days) activities involving key process participants focused on specific improvement areas. The question asks if the assertion is false, and since the description is true, the assertion that it is false is incorrect.

Question 11: Visual check system for reviewing important workplace items: leader task boards. It consists of a set of duties connected to daily management, leader standard work, production, cost, and quality.

False
True (Correct answer)

Correct answer: True

The statement is true. Leader task boards are a visual management tool used in Lean environments to provide leaders with a clear, concise overview of daily management tasks, standard work adherence, and key performance indicators related to production, cost, and quality. They facilitate quick checks, promote accountability, and ensure consistent execution of daily management routines.

Question 12: This strategy, which takes its cues from Hoshin Kanri, is called Catchball and it aims to take employee input into account while deciding on the path of the company. It's frequently used when formulating things like mission statements and goals, with the concept being that management and staff will "throw" and "catch" each other's ideas and work together to produce the desired outcome.

False
True (Correct answer)

Correct answer: True

The statement is true. Catchball is a strategic planning and deployment process, inspired by Hoshin Kanri, that emphasizes iterative communication and negotiation between management and employees. It involves 'throwing' down strategic ideas and 'catching' feedback and refinements from various organizational levels, ensuring alignment, buy-in, and a shared understanding of goals and mission statements.

Question 13: Lead Time: The period of time between when a consumer puts an order and when they actually receive the products or services they ordered.

False
True (Correct answer)

Correct answer: True

The statement is true. Lead Time is a critical metric in process management, representing the total duration from the moment a customer places an order until they receive the final product or service. It encompasses all stages, including order processing, production, and delivery, and is a key focus for reduction in Lean methodologies.

Question 14: This method of resource conservation through waste reduction is regarded as the forerunner to lean manufacturing. The two fundamental ideas of "The Toyota Way" are Jidoka, which means identifying the immediate root cause of any production-related issues, and Just-in-Time, which means only creating what is required and not keeping surplus inventory. Only through believing in and empowering employees to participate in the system is this potent combination achievable.

Pdca (aka plan do check adjust)
Gemba Walk (aka process Walk)
Total Quality Management (aka Tqm)
Toyota Production System (aka TPS) (Correct answer)

Correct answer: Toyota Production System (aka TPS)

The description accurately defines the Toyota Production System (TPS), which is widely recognized as the precursor to lean manufacturing. TPS is built upon two foundational pillars: Jidoka (automation with a human touch, stopping for defects) and Just-in-Time (producing only what is needed, when needed), all empowered by employee involvement to eliminate waste and conserve resources.

Question 15: A methodical approach of removing waste from a process with the intention of giving the customer what they want. This method is largely composed of tools that Toyota developed while developing the Toyota Production System.

Push
Pull
Lean (Correct answer)
Cycle Time

Correct answer: Lean

Lean manufacturing (or simply Lean) is a systematic methodology focused on identifying and eliminating waste from processes to maximize customer value. It originated from the Toyota Production System and employs various tools and principles to streamline operations, reduce lead times, and improve quality by removing non-value-added activities.

Question 16: The premise that things should move from one procedure to another in the shortest possible increments, one piece being optimal.

Non-utilized Talent
Single-Piece-Flow (Correct answer)
Overproduction
Cycle Time

Correct answer: Single-Piece-Flow

Single-Piece-Flow (also known as One-Piece Flow) is a fundamental Lean principle that advocates for products to move through the production process one unit at a time, without accumulating in batches. This approach minimizes work-in-process inventory, reduces lead times, and allows for quicker detection of defects, promoting continuous movement and value creation in the smallest possible increments.
