    I am new to the Six Sigma and i was looking over some of the things posted on the web and was wondering can a process be in control because it can drift 1.5 sigma from the mean and not produce a defect
    with a CP=2 and a Cpk =1.5

    Bob,
    Peruse the blue bar to the left and click on, ‘New To Six Sigma?”.   Your journey will begin there.

    The best way to understand this is by dropping the letter F from shift. Read what it says a few times, and be enlightened.

    There is no link between if a process is in control and if it’s producing defects. This is a common error which lots of people make, control is just about variation in the process not about how that links to customer specifications.
    A process can be in perfect control in that it produces the same thing everytime but everything it produces is defective and the reverse can be true as well.
