A Z-Transform is an equation that transfers a set of data represented by a normal distribution into a standard normal distribution (mean equals zero and standard deviation equals one) by subtracting the original mean from […]
Yield is the ratio of the number of units that meet certain criteria to the number of units that enter into the process. The criteria determines if a yield is Traditional Yield or another kind […]
The Z-Distribution is a special case of the normal distribution in which the mean equals zero and the standard deviation equals one. Z-Distribution
A Z-Score is a standardized score for measuring process performance relative to customer requirements. The Z-Score is very useful in the DFSS methodology. Z-Score
A Z-Table is a statistical table of probabilities associated with the Z-distribution or standard normal distribution. Z-Table
If learning complex math, arithmetic, or statistics isn’t needed then why introduce Statistical Process Control or SPC for short? SPC simply put is a quality control method employing statistical methods. Statistical Process Control is applied […]
The Voice of the Process (VOP) encompasses the entire range of the output (Y) of a process when all of the X\’s in the Y = f(x) equation have varied their full range. Voice of […]
Y=f(x) is the mathematical relationship that identifies the inputs (X\’s) that need to be controlled and the levels they need to be set at to achieve the desired output (Y) to meet customer requirements. Y=f(x) […]
