D469 Quality, Continuous Improvement, and Lean Six Sigma - Set 3 - Part 2

Correct Answer: Eliminating waste and increasing efficiency

Lean methodology focuses on eliminating waste in processes to create value for the customer while increasing operational efficiency.

Correct Answer: 3.4 defects per million

A Six Sigma process is designed to produce no more than 3.4 defects per million opportunities, representing a high level of quality and consistency.

Correct Answer: Map the entire process from suppliers to customers

A SIPOC diagram provides a high-level view of a process, showing how suppliers, inputs, the process, outputs, and customers are interconnected.

Correct Answer: Smoothing production to reduce fluctuations

Heijunka is a Lean technique that focuses on leveling production schedules to reduce fluctuations and create a steady workflow.

Correct Answer: Monitoring process variation over time

Control Charts help track how a process behaves over time by plotting performance data, identifying trends, and highlighting variations.

Correct Answer: Displaying process data in real-time

Visual Management uses visual tools and displays to communicate important process information, making it easy for employees to monitor performance and identify problems.

Correct Answer: Quantifying the current state of the process

The Measure phase is where the current performance of the process is quantified, providing a baseline for future improvements.

Correct Answer: Ensure process improvements are sustained

A Control Plan documents the steps needed to maintain process improvements and ensure that the process remains stable over time.

Correct Answer: The relationship between inputs (x) and outputs (Y)

Y=f(x) is a fundamental concept in Six Sigma, which represents the relationship between the outputs of a process (Y) and the inputs or variables (x) that affect the process.

Correct Answer: Show the distribution of data points

A Histogram is a graphical tool that shows the frequency distribution of data points, helping to visualize variation within a dataset.

Correct Answer: Identify the underlying cause of a defect or issue

Root Cause Analysis is used to identify the fundamental cause of a problem, enabling teams to address the issue at its source.

Correct Answer: Eliminating waste and improving process efficiency

Kaizen is a Japanese term meaning "continuous improvement," focusing on making small, incremental improvements to eliminate waste and enhance efficiency.

Correct Answer: Monitor the average of a process over time

An X-bar Chart monitors the average (mean) of a process over time, helping to identify shifts in the process mean.

Correct Answer: Value Stream Mapping

Value Stream Mapping is a Lean tool used to visualize the entire process and identify unnecessary steps or waste.

Correct Answer: Cause and Effect Diagram

A Fishbone Diagram, also known as a Cause and Effect Diagram, is used to identify the potential causes of a problem in a process.

Correct Answer: The percentage of products that meet quality standards

Process Yield is a measure of the percentage of products or services that meet quality standards without requiring rework or defect correction.

Correct Answer: Define, Measure, Analyze, Improve, Control

DMAIC is a structured approach used in Six Sigma to improve processes, focusing on defining the problem, measuring performance, analyzing root causes, improving the process, and controlling the results.

Correct Answer: Transportation of materials between workstations

Non-value-added activities are those that do not directly add value to the product or service from the customer's perspective, such as excessive transportation of materials.

Correct Answer: To validate the effectiveness of a proposed solution

Hypothesis testing is used to determine whether a proposed solution or change to the process has a statistically significant impact on the outcome.

Correct Answer: A visual tool used to manage inventory and production

Kanban is a visual scheduling tool used to manage the flow of materials and production based on actual demand, preventing overproduction.
