Process and Measurement System Capability Analysis<br />Process capability involves evaluating process variability relative to preset product specifications in order to determine whether the process is capable of producing an acceptable product<br />To produce an acceptable product, the process must be capable and in control before production begins<br />

Acceptance Sampling for Attributes and Variables<br />Acceptance sampling refers to the process of randomly inspecting a certain number of items from a lot or batch in order to decide whether to accept or reject the entire batch<br />A sampling plan is required for acceptance sampling that precisely specifies the parameters of the sampling process and the acceptance/rejection criteria<br />
Acceptance Sampling for Attributes and Variables<br />Sampling plan for attributes<br />Lot size (N) = 100,000<br />Inspection level = Normal<br />Acceptance quality level (AQL) = 2%<br />Sample size code letter = N<br />Sample size (n) = 500<br />Acceptance number (c) = 18<br />
Acceptance Sampling for Attributes and Variables<br />Sampling plan for variables<br />Lot size (N) = 100,000<br />Inspection level = Normal<br />Acceptance quality level (AQL) = 2%<br />Sample size code letter = O<br />Sample size (n) = 100<br />Acceptance number (k) = 1.765<br />
ISO Standardization<br />ISO develops international standards of quality for all industrial standards<br />ISO has gained popularity and recognition because of the facts that it controls quality, it saves money, customers expect it and competitors use it<br />ISO 9000 and ISO 14000<br />
ISO Standardization<br />PROCON strictly follows the ISO standards of quality and its QMS is based entirely on the ISO 9000 family<br />The compatible standard that applies to PROCON is ISO T/S 16949 quality specification for automotive industry supplier<br />
Application of Six Sigma Approach<br />Six Sigma Quality is defined as a high level of quality associated with approximately 3.4 defective parts per million<br />Six Sigma simply means a measure of quality that strives for near perfection<br />A Six Sigma defect is defined as anything outside of customer specifications<br />
Application of Six Sigma Approach<br />There are two aspects to implementing the Six Sigma concept: DMAIC and DMADV<br />The first is the use of technical tools to identify and eliminate causes of quality problems<br />The second aspect of Six Sigma implementation is people involvement<br />
Critique of the Quality Control System<br />The objective is to study, evaluate and critically analyze the quality control system of the company<br />The quality control measures for the most part conform to the standard operating procedure<br />One drawback of the quality control system of PROCON is its cost<br />Overall, the quality control system is highly efficient and effective at establishing and maintaining quality<br />
