Off-road vehicle drivetrains. Later, during the 1990s, manufacturers started to add even more luxuries to bring those off-road vehicles on par with regular cars. This eventually evolved into what we call the SUV today. It also evolved into the newer crossover vehicle, where utility and off-road capability was sacrificed for better on-road handling and luxury. To be able to drive off the pavement, off-road vehicles need several characteristics: They need to have a low ground pressure, so as not to sink into soft ground, they need ground clearance to not get hung up on obstacles, and they need to keep their wheels
Process capability index mean is T, the estimated mean of the process is formula_1 and the estimated variability of the process (expressed as a standard deviation) is formula_2, then commonly accepted process capability indices include: formula_2 is estimated using the sample standard deviation. Process capability indices are constructed to express more desirable capability with increasingly higher values. Values near or below zero indicate processes operating off target (formula_1 far from T) or with high variation. Fixing values for minimum "acceptable" process capability targets is a matter of personal opinion, and what consensus exists varies by industry, facility, and the process under consideration. For
