Statistical Process Control (SPC) Implementation

Statistical Process Control Training and Implementation

Statistical Process Control (SPC) is a set of techniques that provides a clearer understanding of the evolution and behavior of a process or system. Furthermore, SPC can be utilized to understand any industrial and service oriented process. Applications include manufacturing, customer service, health care, accounting, banking, insurance, investing, and so on.

Typically, companies react to a process when a problem has already occurred. Every time we react to process problems, the process is controlling our behavior. In essence, we are responding to the process instead of controlling it. The purpose of SPC is to control our processes rather than be controlled by them.

When applied properly, Statistical Process Control strengthens our knowledge of a process or system, and it allows us to prevent detrimental outcomes. SPC also indicates when an improvement has occurred so that we can identify the cause.

Although SPC was invented in 1924, most companies still do not appreciate its value because when SPC is implemented, it is almost always misused and misunderstood. The result is that companies in every industry continue to struggle with the need or desire to consistently and competently apply Statistical Process Control throughout their organizations.

Most organizations find themselves in one of three categories:

  • No internal expertise with statistical methods,
  • One or select few individuals with statistical methods competency, but no widespread or systematic application of SPC, or
  • Widespread but improper and inappropriate application of Statistical Process Control methods.

The traditional cause of these shortcomings is that practitioners of statistical methods have been too academic with the transfer of their knowledge and have failed to develop practical tools that allow a "lay person" to use Statistical Process Control in their daily work. Furthermore, many practitioners are not up to date on the most modern SPC methods.

SPC-IQ® is a truly unique approach to the implementation of SPC and Measurement System Assessment (MSA). SPC-IQ® allows any person in your company (with even the most basic mathematics and computer skills) to identify and apply the most appropriate and modern SPC techniques to their daily work. They will even be able to interpret the outcome. Furthermore, for the first time, SPC-IQ® has turned SPC and MSA implementation into a defined business processes that can be seamlessly integrated into your business operating system (BOS) and/or quality management system (QMS).

SPC-IQ® introduces two Support Processes and 14 supporting step-by-step Work Instructions:

  1. SP-8230 Process Stability & Capability (SPC)
    1. WI-8230-01 Determining Sample Size & Frequency
    2. WI-8230-02 Testing For Normality of Data
    3. WI-8230-03 I-MR Charts for Normal & Non-Normal Data
    4. WI-8230-04 Constructing CUSUM & EWMA Charts
    5. WI-8230-05 Xbar/Rb/Rw & Xbar/Rb/d Charts
    6. WI-8230-06 Xbar-R & Xbar-S Charts
    7. WI-8230-07 np, p, & Standardized p Charts
    8. WI-8230-08 c, u, & Standardized u Charts
    9. WI-8230-09 Testing For Location/Position Differences
    10. WI-8230-10 Stability Assessment - Control Chart Interpretation Guide
    11. WI-8230-11 Capability Assessment
  2. SP-7610 Measurement Systems Assessment (MSA)
    1. WI-7610-01 Attribute Gage R&R Study
    2. WI-7610-02 Variable Gage R&R Study
    3. WI-7610-03 Linearity Assessment

SPC-IQ® includes MSA because understanding measurement system (gage) variability, capability, and reliability is vital to the success of SPC implementation.

Both processes are presented in the form of Process Maps to aid in training, retention, and ease of use. Together these Process Maps guide the user through all of the process steps and decisions needed to identify the appropriate SPC method and to assess the capability of a measurement system.

Each Process Map also includes direct links to each of the 14 Work Instructions that detail how to use Minitab 15 statistical software to set up data and studies, apply each Statistical Process Control technique, and how to generate and interpret the outcome. The Work Instructions include actual Minitab 15 screen shots that the user will see every step of the way.

SPC-IQ® is provided as stand-alone set of documents, as an element of the Lean QMS® Curriculum, or as a stand-alone workshop.

SPC-IQ® Workshop Agenda

Preparation for Workshop

Pinnacle customizes all of its services to be relevant to each individual client. For this reason, Pinnacle's instructor will provide you with a data collection worksheet prior to the SPC-IQ® Workshop. You will use the worksheet to collect process data from two of your actual industrial and/or service oriented processes. The completed worksheet will be used during the SPC-IQ® Workshop. This ensures that participants experience SPC implementation in their everyday work environment.

SPC-IQ® Workshop Format

Because Pinnacle customizes all training and consulting service, this workshop is presented on-site to groups of up to 12 individuals. All discussions and examples are relevant to your organization. The delivery style is interactive and participants are encouraged to ask questions.


By the end of the SPC-IQ® Workshop your organization will have processes that address SPC and MSA that your employees will understand and use. The processes will also empower the employees with the understanding of what their process is really doing and how their work may influence it. The net result is that modern statistical methods become integral components of your organization's BOS and/or QMS.
