Introduction to SPC
- Key objectives of SPC: prevention vs detection
- The importance of process centring
- Using data for continuous process improvement
- The limitations of specification-based systems
- Sources, causes and types of variation
Pre-requisites to SPC
- Planning data collection and checking measurement system
- Frequency distributions and normal distribution
Control Techniques
- Overview of mistake proofing
- Pre-control charts; Reduced and sample inspection
Control Charts and their Applications
- Control charts for variables (I-MR, X-Bar R, X -Bar s)
- I-MR. X-Bar R, X -Bar s charts and how to use them
- Links to additional quality tools
SPC Techniques for Special Situations
- Short run SPC
- Handling more than one characteristic
Control Charts for Attributes (P, NP, C, U)
- P and NP charts
- Setting up the charts; interpreting results
- C and U charts
Evaluating Process Capability
- Capability analysis of variables data (Cp,Cpk,Pp,Ppk)
- Dealing with non-normal data
- Single sided tolerances
- Capability analysis for Attribute data (PPM, DPMO)
- Implementing SPC and process capability in the workplace
