What are swimlane diagrams?

Swimlane diagrams are flowcharts that include lanes to separate responsibilities for different participants or departments involved in a process.

What are the measures of central tendency?

The measures of central tendency include mean, median, and mode, which summarize a data set by identifying the center point.

What is standard deviation?

Standard deviation is a statistic that measures the dispersion or variability of a dataset relative to its mean.

What is normal distribution?

Normal distribution is a probability distribution that is symmetric about the mean, representing data that clusters around a central value.

What is measurement system analysis (MSA)?

Measurement System Analysis is a methodology that evaluates the accuracy and precision of measurement systems.

What is Gage R&R?

Gage R&R (Repeatability and Reproducibility) is a statistical tool used to assess the variability in measurement systems.

What is process capability?

Process capability refers to the ability of a process to produce output within specified limits, measured using attributes like Cp and Cpk.

How do you calculate Cp, Cpk, Pp, and Ppk?

Cp and Cpk measure a process's potential capability, while Pp and Ppk measure the actual performance over time, using specific formulas.

What are the 5 Whys?

The 5 Whys is a problem-solving technique that involves asking 'why' multiple times to drill down to the root cause of an issue.

What are Fishbone or Ishikawa diagrams?

Fishbone diagrams are visual tools that identify many potential causes of a problem, organizing them into categories.

What is hypothesis testing?

Hypothesis testing involves using statistical methods to determine if there is enough evidence to reject a null hypothesis.

What are p-values?

A p-value is a statistical measure that helps determine the significance of results in hypothesis testing.

What are t-tests used for?

T-tests are used to compare the means of two groups to determine if they are significantly different from each other.

What is ANOVA?

ANOVA (Analysis of Variance) is a statistical method used to compare means among three or more groups.

What is a chi-square test?

A chi-square test measures how expectations compare to actual observed data to assess associations between categorical variables.

What is correlation?

Correlation measures the degree to which two variables move in relation to each other.

What is regression analysis?

Regression analysis is a statistical method for examining the relationship between dependent and independent variables.

What is FMEA?

FMEA (Failure Mode and Effects Analysis) is a systematic method for evaluating potential failure modes and their impact on a process.

What is Poka-Yoke?

Poka-Yoke is a mistake-proofing technique designed to eliminate human error in processes.

What is Kaizen?

Kaizen is a philosophy that focuses on continuous improvement by involving all employees in enhancing processes and eliminating waste.

What are Design of Experiments (DOE)?

Design of Experiments is a statistical method to plan, conduct, and analyze controlled tests to evaluate the factors that may influence a process.

What is Statistical Process Control (SPC)?

Statistical Process Control involves using statistical methods to monitor and control a process to ensure it operates at its full potential.

What are control charts?

Control charts are tools used in SPC to track process data over time and identify any variations that may indicate a problem.

What is an I-MR chart?

An I-MR chart is a type of control chart that monitors individual values and moving ranges in a process.

What is an X-bar R chart?

An X-bar R chart is used to monitor the mean and range of a process based on subgroups of data.

What is a C-chart?

A C-chart is a type of control chart used for monitoring the number of defects in a process.

What is a P-chart?

A P-chart is a control chart used to monitor the proportion of defective items in a process.

What is a Control Plan?
