Many a times, the specification limits are not rightly set. This is because of lesser customer awareness on the subject. Therefore, the specification limits are always met despite a wide gap between what is achievable and what are the current specification limits One of the example could be newly transitioned processes from an onshore location where the customer does not have enough empirical data to set the LSL & USL. A point in context here is the specification limits are ever changing. In the cited example, once customer knows that, we are meeting the expectations he redraws the targets and at times, these are beyond comprehension. Regupathi Krishnan.
