3. Control Charts: The Voice of the Process
One of the most significant contributions of Mahajan’s text is the detailed explanation of Control Charts. These are the "traffic signals" of production.
- X-bar and R Charts: Used for variable data (things you can measure, like length, weight, or temperature). The X-bar chart tracks the average performance, while the R chart tracks the variability. If a point falls outside the Upper or Lower Control Limits (UCL/LCL), the process is "out of control," signaling an immediate need for investigation.
- p-charts and c-charts: Used for attribute data (things you can count, like the number of defects). The p-chart monitors the proportion of defective items, while the c-chart monitors the count of defects per unit.
Mahajan emphasizes that the purpose of these charts is not to catch the worker, but to catch the process failure. They provide a visual history of the process capability.
B. Acceptance Sampling
Acceptance Sampling is reactive. It involves inspecting a random sample from a batch (lot) to decide whether to accept or reject the entire batch.
- The Goal: To ensure that the final product meets customer standards without the prohibitive cost of 100% inspection.
- The Outcome: Determining the quality of the output after production is complete.
6. The Economic Impact
Perhaps the most practical aspect of Mahajan's writing is the focus on cost. SQC is not applied for its own sake; it is applied to minimize the Cost of Quality. This includes:
- Prevention Costs: Training and planning.
- Appraisal Costs: Inspection and testing.
- Failure Costs: Scrap, rework, and warranty claims.
By utilizing SQC, organizations find the optimal balance—spending enough on prevention and appraisal to drastically reduce the cost of failures. Statistical Quality Control By Mahajan.pdf
