- Question 1Intermediate
Lean Principles · The 8 Wastes (DOWNTIME)
A manufacturing plant manager is concerned about workplace organization and efficiency. She observes that tools are often misplaced, work areas are cluttered, and time is wasted searching for necessary items. Which Lean methodology would most directly address these specific problems?
Show answer & explanation
Correct answer: C
5S (Sort, Set in Order, Shine, Standardize, Sustain) is a systematic method for organizing a workspace for efficiency and effectiveness. It directly targets problems like clutter, misplaced tools, and wasted search time.

DMAIC Methodology · Measure Phase
A project team is in the 'Measure' phase of a DMAIC project. Which of the following activities are characteristic of this phase? (Select TWO)
Show answer & explanation
Correct answers: B, D
A key goal of the Measure phase is to quantify the current state or 'as-is' performance of the process. This baseline provides a starting point against which improvements can be compared.
After defining what needs to be measured, the team executes a plan to collect the necessary data to understand the process and establish its baseline performance.
- Question 3Beginner
Six Sigma Fundamentals · Voice of the Customer (VOC)
The term 'Voice of the Customer' (VOC) is fundamental to Six Sigma. It is primarily used to:
Show answer & explanation
Correct answer: C
The core purpose of VOC is to capture customer feedback, needs, and expectations. This information is then translated into specific, measurable characteristics known as Critical to Quality (CTQ) requirements that the process must deliver.
- Question 4Intermediate
Lean Principles · The 8 Wastes (DOWNTIME)
A call center is analyzing its processes. It is discovered that customer service agents frequently have to ask customers to repeat their account information because the information is not automatically transferred when a call is escalated from a junior to a senior agent. This redundant questioning is an example of which of the 8 Wastes?
Show answer & explanation
Correct answer: D
Extra-Processing (or Over-processing) refers to performing more work than is necessary. Re-entering or re-collecting data that has already been provided is a classic example of this waste in a service environment.

DMAIC Methodology · Define Phase
Case Study
A mid-sized e-commerce company, 'QuickShip Goods', has been receiving an increasing number of customer complaints about delayed shipments. The company's goal is to ship all orders within 24 hours of receipt, but internal data shows they are only meeting this goal 75% of the time. The Operations Manager, who has a basic understanding of continuous improvement, wants to launch a formal project to address this issue.
The manager assembles a team including warehouse staff, customer service representatives, and an IT specialist. He states the problem as 'customers are unhappy with shipping times'. He wants the team to immediately start testing solutions, such as hiring more staff or buying a new software system, to see what works.
As a team member with Lean Six Sigma White Belt knowledge, what is the most critical first step of the DMAIC process that the manager is overlooking?
Show answer & explanation
Correct answer: C
The manager is jumping directly to the 'Improve' phase (testing solutions) without a structured foundation. The most critical missing step is from the 'Define' phase. A Project Charter would formalize the problem statement (e.g., 'Increase on-time shipment rate from 75% to 95% within 6 months'), set a measurable goal, define the project's scope (what's in and out), and align the team before any work begins.
- Question 6Advanced
Six Sigma Fundamentals · History and Evolution of Six Sigma
Which of the following statements best describes the relationship between Lean and Six Sigma?
Show answer & explanation
Correct answer: C
This is the most accurate description. Six Sigma uses statistical tools to tackle variation and improve process capability (quality), whereas Lean uses tools like 5S and Value Stream Mapping to eliminate non-value-added steps and increase speed and efficiency. Together, they create a powerful, holistic approach to process improvement.
- Question 7Beginner
Lean Principles · Lean Culture and History
The Japanese term for continuous improvement, which is a core philosophy of Lean, is known as __________.
Show answer & explanation
Correct answer: B
Kaizen is the Japanese philosophy of continuous improvement, involving all employees from the CEO to the front-line workers. It focuses on making small, incremental changes on a regular basis.
- Question 8Beginner
Roles and Responsibilities · Champions and Sponsors
Which Six Sigma role is typically a senior manager who provides resources, removes organizational barriers, and ensures the project aligns with strategic business goals?
Show answer & explanation
Correct answer: C
The Champion, also known as the Project Sponsor, is a senior leader who owns the project from a business perspective. Their responsibilities include securing funding and resources, removing organizational obstacles, and ensuring the project's objectives are aligned with the company's strategic vision.
- Question 9Beginner
Basic Quality Tools · Process Mapping Basics
A team is creating a high-level process map to understand the scope of their project. They want to identify the key parties involved and the major steps. They create a diagram that lists Suppliers, Inputs, Process, Outputs, and Customers. What is this type of diagram called?
Show answer & explanation
Correct answer: C
SIPOC stands for Suppliers, Inputs, Process, Outputs, and Customers. It is a high-level process map used in the 'Define' phase of DMAIC to clarify the scope and key elements of a project before diving into details.
- Question 10Intermediate
DMAIC Methodology · Control Phase
During the final phase of a DMAIC project, the team implements a new checklist for processing invoices to ensure accuracy. They also document the new procedure and provide training to all accounting clerks. Which phase of DMAIC do these activities belong to?
Show answer & explanation
Correct answer: C
The Control phase is focused on ensuring that the improvements are sustained over time. Key activities include updating documentation, creating standard operating procedures (SOPs), training employees on the new process, and establishing a monitoring plan. These actions lock in the gains achieved.
