A process is a sequence of actions with inputs and outputs, linked by a feedback loop to improve output. In SPC, use control charts and process capability to manage variation.
Learn how to summarize data using central tendency by computing the mean, median, and mode, and understand how these measures relate to dispersion and histogram peaks.
Explore the three measures of dispersion—range, standard deviation, and variance—and how they describe data spread, including population versus sample standard deviation and their role in control charts.
Explore probability distributions in SPC: use the normal distribution for continuous data and binomial or Poisson for discrete data in control charts.
Understand the normal distribution for continuous data, its symmetry and mean–mode–median equality, and how mean and standard deviation define probabilities within 1–3 standard deviations for SPC control limits.
Explore type I and type II errors in control charts. Distinguish false alarms from missed process changes and learn how subgroup size influences these errors.
Explore control charts basics, including seven common charts for attribute and variable data, with cusum and ewma, and practice creating control limits in Excel and Minitab.
Learn to construct a P chart for proportion defective using Excel and Minitab, calculating P-bar, upper and lower control limits, and applying it to varying subgroup sizes.
Explore the U chart theory for attributes when subgroup size varies, using proportion defects and U bar, with changing control limits and examples in Excel and Minitab.
Learn the x bar s chart for variable data when subgroups exceed nine, using standard deviation and control limits with A3, B3, and B4, plus plotting in Excel and Minitab.
Discover how EWMA and CUSUM time-weighted control charts detect very small shifts in the process mean using lambda weighting and moving averages.
Explore how control charts assess process stability and capability using I and MR charts, UCL and LCL, and specification limits, with Cp, Cpk, Pp, and Ppk.
Explore the difference between sigma within and sigma overall, and how Cp, Cpk, Pp, and Ppk relate to short-term versus long-term process capability, using Rbar, D2, and Excel/Minitab.
Compare Cp, Cpk with Pp, Ppk, showing how long-term standard deviation affects Pp and Ppk through Excel and Minitab demonstrations. Emphasize asking suppliers for Ppk to assess overall process capability.

Statistical Process Control (SPC) is one of the core IATF 16949 tools.
To confirm if the process is in statistical control, we use Control Charts.
To check if the process can produce output that meets specifications, we perform Process Capability Studies.
This course covers both aspects of Statistical Process Control (SPC): Control charts and Process Capability Studies.
This is the basics-to-advanced course on Statistical Process Control (SPC).
In fact, this is a 4-in-1 course.
Course 1: Statistics Foundation: To understand Control Charts and Process Capability, you need to have a basic understanding of statistical concepts, including probability distributions. Section B of this covers all that you need to understand SPC better.
Course 2: Control Charts/Process Capability Using Minitab: Minitab is the most advanced tool used by professionals to plot Control Charts and perform the Process Capability Analysis.
Course 3: Control Charts/Process Capability Using Excel: In addition to Minitab, you will understand how to perform all these calculations using Microsoft Excel. Minitab is costly and not everyone might have access to Minitab. Microsoft Excel is widely accessible. In addition, when you perform calculations using Excel, you get a much better understanding of what is happening under the hood.
Course 4: Process Capability Analysis: Control Charts just tell if the process is in control or not. To check whether the process is capable, you need to perform the Process Capability Analysis. This course covers all the calculations using Excel and Minitab.
