Process and Measurement System Capability Analysis 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 To produce an acceptable product, the process must be capable and in control before production begins

56. Acceptance Sampling for Attributes and Variables 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 A sampling plan is required for acceptance sampling that precisely specifies the parameters of the sampling process and the acceptance/rejection criteria
57. Acceptance Sampling for Attributes and Variables Sampling plan for attributes Lot size (N) = 100,000 Inspection level = Normal Acceptance quality level (AQL) = 2% Sample size code letter = N Sample size (n) = 500 Acceptance number (c) = 18
58. Acceptance Sampling for Attributes and Variables Sampling plan for variables Lot size (N) = 100,000 Inspection level = Normal Acceptance quality level (AQL) = 2% Sample size code letter = O Sample size (n) = 100 Acceptance number (k) = 1.765

62. ISO Standardization ISO develops international standards of quality for all industrial standards ISO has gained popularity and recognition because of the facts that it controls quality, it saves money, customers expect it and competitors use it ISO 9000 and ISO 14000
63. ISO Standardization PROCON strictly follows the ISO standards of quality and its QMS is based entirely on the ISO 9000 family The compatible standard that applies to PROCON is ISO T/S 16949 quality specification for automotive industry supplier
64. Application of Six Sigma Approach Six Sigma Quality is defined as a high level of quality associated with approximately 3.4 defective parts per million Six Sigma simply means a measure of quality that strives for near perfection A Six Sigma defect is defined as anything outside of customer specifications
65. Application of Six Sigma Approach There are two aspects to implementing the Six Sigma concept: DMAIC and DMADV The first is the use of technical tools to identify and eliminate causes of quality problems The second aspect of Six Sigma implementation is people involvement
66. Critique of the Quality Control System The objective is to study, evaluate and critically analyze the quality control system of the company The quality control measures for the most part conform to the standard operating procedure One drawback of the quality control system of PROCON is its cost Overall, the quality control system is highly efficient and effective at establishing and maintaining quality
