Control Charts

The control chart is the fundamental tool of Statistical Quality Control (SQC). It denotes the general cause variation in which is built into a system therefore permit the user to determine the procedure consistency and continuity. Special causes can be assigned for a process that is out of control or going to be out of control. The bounds of the control chart are marked through upper and lower control limits that are computed through applying statistical formulas to data from the procedure. Data points which fall outside these bounds represent variations because of special causes that can typically be found and eliminated. The most generally used SQC charts are X and R Charts, P Chart and C Chart.

Mere use of the quality control tools does not essentially constitute a guarantee to achieve drastic improvements in quality. It is imperative to build an environment and a system in which will continuously promote quality in all aspects of its operation. The basic reasons of the whole quality program along with the help of performance benchmarking and KPI data capturing is improvement in the procedure, in a particular methodology that involve:

  • Discovery;
  • Analysis;
  • Improvement;
  • Monitoring;
  • Implementation; and
  • Verification.
