Basic Statistical Techniques


This course is designed to provide participants with the statistical tools needed to drive improvement of business processes throughout the entire organization. Participants will learn how to select the most appropriate statistical tool, and then will have an opportunity to implement SPC within their own jobs.


Held in a workshop format, this 4-day course is designed to teach participants the application of basic statistical process control techniques. The focus of this workshop is to enable participants to stabilize and to achieve improvements in the output of processes. Unlike typical SPC courses that only teach control charting techniques, this workshop enables participants to learn how to actually achieve measurable gains in the output of their processes. The intent is to significantly reduce the process variation and to improve quality.

Participants will learn through lecture, class discussions, class exercises, case studies and team breakouts. This workshop is often greatly enhanced by the inclusion of real-life company data (for in-house courses). Participants have the opportunity to apply SPC tools to a number of actual plant or office situations. It can also be customized to be spread out over a number of weeks—to enable participants to practice the application of the techniques.

SatiStar’s experts can follow-up this training with on-site consultants to ensure that the use of the tools is applied effectively.

SatiStar's Experience Makes The Difference!

  • . . . worked extremely well with the departmental and site managers . . . goal oriented and met the objectives set within the quoted budget and ensured the results were attained for the Company.

  • The guys from SatiStar did more in one week than we were able to do in 6 months.

  • Achieving ISO registration was far less onerous than we thought, our employees really rallied to the cause. The registration effort really brought us closer together as a team, and SatiStar really came through for us when we needed them.

  • We started this process a year ago with Mickey helping us create a spaghetti map of our processes on the whiteboard, and then his team guided us through their streamlining methodology and got us to where we are today. Our processes now look nothing like the spaghetti map – and we’re much more efficient today

  • This projected cycle time reduction of over 80% annual cost savings amounting to over 3% of sales, one-time savings of roughly $10 million, and working capital reduction of roughly $30 million really have us excited!

  • An outstanding success with Motorola’s vendor audit! What made this an exceptional achievement is that it typically takes 4 to 5 attempts to pass this audit. SatiStar’s expertise made it easy to avoid all the extra attempts.
