3M
Muda (waste), Mura (irregular, uneven or inconsistent) and Muri (unreasonable or excessive strain)
Machine Capability (Cmk)
capability of a machine to produce a measurable characteristic under short term influences. The minimum requirement is xbar ±5s within tolerance, i.e., 99.99998% of manufactured parts are expected to be within the tolerance. This corresponds to a Cmk factor of 1.67. The ultimate target is a Cmk factor of 2.00. (also ongoing capability)
Maintainability
The probability that a failed system can be made operable in a specified interval or downtime.

Multi Vari
Analysis
a powerful graphical analysis technique used to identify and quantify dominant sources of variation in a process. It is appropriate when the response variable (y) is continuous and the x's under investigation are discrete. Multi-Vari Analysis graphically depicts multiple sources of variation. It allows the examination of major families of variation, including positional (within unit or part), cyclical (unit-to-unit or part-to-part) and temporal (over time). The basic objective of Multi-Vari Analysis is to determine which family exhibits the largest variation.
Multiple Regression
most common statistical technique for predicting the value of a dependent variable in relation to one or more independent variables. Relationships can be linear, non-linear, logarithmic, etc.
