Acronyms and DefinitionsCI (Continuous improvement) - an ongoing effort to improve products, services,processes. Processes are constantly evaluated and improved in the light of theirefficiency, effectiveness and flexibility.DFMEA (Design-Potential Failure Mode and Effects Analysis) - is the application of theFailure Mode and Effects Analysis (FMEA) method specifically to product/service design.SCR (Supplier Change Request) - request for permanent change to part, dimension,tolerance, material, process, method, or standard.MSA (Measurement System Analysis) - Measurement system analysis (MSA) is anexperimental and mathematical method of determining how much the variation withinthe measurement process contributes to overall process variability. There are fiveparameters to investigate in an MSA: bias, linearity, stability, repeatability andreproducibility. An example of MSA is a Gage Repeatability and Reproducibility Study (G,R&R). According to AIAG (2002), a general rule of thumb for measurement systemacceptability is:
