FREE Certified Quality Engineer (CQE) MCQ Questions and Answers

Question 1

Which of the below chart kinds is founded purely on specification limits?

Accepted Answer

PRE-control

Answer

The type of chart that is based directly on specification limits is called a "Control Chart," not "PRE-control." A Control Chart is a graphical tool used in statistical process control to monitor and analyze process performance over time. It is typically used to determine if a process is stable and within specification limits.

Question 2

Which methods are NOT used to assess how well a process adheres to its requirements?

Accepted Answer

Process flowchart

Answer

A Process Flowchart is not typically used to directly compare process performance to specifications.

A Process Flowchart is a visual representation of the steps and sequence of activities in a process. It helps in understanding the flow of materials, information, or activities within a process. The purpose of a Process Flowchart is to identify the various steps, decision points, inputs, outputs, and interactions involved in a process.

Question 3

A ___ is a particular kind of line graph used to evaluate a process's stability.

Accepted Answer

Control chart

Answer

A Control Chart is a type of line graph that is used to assess the stability of a process. It is a key tool in statistical process control (SPC) and is commonly employed in quality management and manufacturing settings.

Control Charts monitor process performance over time by plotting data points on a graph, typically with time on the horizontal axis and the measured process variable on the vertical axis. Control limits, which are derived from the process data and specifications, are also plotted on the chart. The control limits represent the acceptable range of variation for the process.

Question 4

NOT using a process capability analysis

Accepted Answer

Maintain a process in a state of statistical control

Answer

A process capability analysis is not used to maintain a process in a state of statistical control.

Process capability analysis is a statistical method used to assess the ability of a process to consistently meet specifications or requirements. It evaluates the inherent variability of a process and compares it to the specification limits. The analysis provides information about how well the process is capable of producing output within the specified limits.

Question 5

Which of the following is a definition of loss according to Taguchi?

Accepted Answer

Variability and deviation from target

Answer

Taguchi defines loss as a function of variability and deviation from target.

In Taguchi's philosophy, the goal is to minimize the overall loss caused by a product or process not meeting the customer's desired target value. Loss is quantified by considering both variability and deviation from the target value.
