Answer #1

Answer:- Option"A" ---- Natural causes and assignable causes

Explanation:- As per the concept of the SPC statistical process control is used to find that the data collected regarding a process with some variations do fall with in control or not. If the variationa in the process is more then the process may out of control but with less number of variations leads to process to statistical control. The variations that make process control or out of control is depends up on the assignable causes and natural causes only. All other options do not satisy the above statement.

Answer #2

Both Assignable cause which is non random results created by a single identifiable character and natural causes are common failures that may occur.

    What does the phrase “in control” mean with respect to processes? An in-control process is one in which the output falls within the specification limits. An in-control process is statistically stable; it is free of assignable or non-random variation An in-control process is one in which the process width (i.e., 6σ) is substantially wider than the specification width (i.e., the upper specification limit minus the lower specification limit) None of these is correct
