InfinityQS software automates SPC, eliminating human error and the need for paper records. A state of statistical quality control, in which an operation produces articles that remain consistently within their range of chance variation, so that no assignable or findable cause is present, is not usually found where statistical control techniques have not been used. A state of control must be established at a satisfactory quality level before maximum efficiency in the operation can be obtained. More commonly known as statistical process control (SPC), this methodology was in use long before computers; however, today most companies use SPC software to inspect their products. Statistical Process Control (SPC) is an industry-standard methodology for measuring and controlling quality during the manufacturing process. Publish your original essays now.
