Process Capability Analysis

This one-day programme is one of a series of courses teaching the use of statistical methods to measure, understand and improve process performance. Process Capability uses statistical calculations to determine the ability of the process to meet specifications using Cp/CpK indices.

  • Capability Principles
  • Basic Statistics and Normality of Data
  • Cp/CpK Indices (and Pp/PpK)

Hypothesis Testing

Hypothesis tests are used to determine whether differences between sample statistics are statistically significant. For example: We assessed 300 pieces of work processed by Team 1 and 30 were defective (10%) and for Team 2, the defective rate was 45 out of 300 (15%). Although these results appear to prove Team 2 is performing worse, this difference is not statistically significant so any business decision based on thinking Team 2 was worse has a high risk of being wrong.

  • Confidence Intervals and Hypothesis Testing Principles
  • T-Tests, One Way ANOVA
  • Standard Deviations Tests and Chi Square Tests
  • Assumptions for the Tests and Checking Assumptions
  • Power and Sample Size / Type 1 and 2 Errors

Design of Experiments

DoE is a structured statistical technique for establishing cause and effect relationships, which in turn form the foundation for organisational learning.  Due to their efficient use of data and deployment in a team environment, learning occurs at an accelerated pace, critical in today’s highly competitive markets.

  • Screening and Optimising
  • Full and Fractional Factorial Experiments
  • Planning, Running, Analysing a DoE
  • Checking assumptions
  • Visualising the Response
  • Predictions and Optimisation

Measuring Process Performance using Minitab

Businesses need to be able to measure, understand and communicate the true performance of their processes to enable process control, improvement and decision making. This requires that the right measures are identified, the data is reliable and sampled appropriately and that the data is turned into useful information which describes the process honestly.

  • Operational Definitions
  • Gauge R&R Study
  • Process sampling and data collection
  • Summarising and presenting data
  • Statistical Process Control using the Individuals Chart
  • Process Capability Analysis (Cp/Cpk)

Analysing Process Performance using Minitab

When good quality data is available, businesses want to be able to extract the maximum information from it in order to increase process understanding. What factors affect process performance? Which do not? What is the size and nature of the effect of factors on output performance? This programme provides detailed training in the practical application of Hypothesis Testing and Regression Analysis which are used to answer these questions.

Our 3 day programme Measuring Process Performance using Minitab provides the skills needed to obtain high-quality process data and is often taken prior to this course.

  • t-test, ANOVA, Chi Square Tests
  • Simple Linear, Multiple Regression and Logistic Regression
  • An Introduction to Design of Experiments
  • The background statistical knowledge to correctly apply, interpret and communicate the above

Reliability and Survival Analysis

Products and systems are expected to function at the time of delivery and for a certain time afterwards. The life of the product can be measured in hours, miles, cycles-to-failure, stress cycles etc. These measurements are known as life data. Reliability is “Quality over Time”.

  • Censored Data
  • Parametric and Non-Parametric Analysis
  • Accelerated Life Testing
  • Shelf Life
