  • Eight Dimensions of Quality
    • Performance  Inspection right off assembly
    • Features  Seat recliners and comforters
    • Reliability  Performance tests (pressure/temperature)
    • Conformance  Design diagram during production
    • Durability  Process capability
    • Serviceability  Rework Redesign
    • Aesthetics  Style, color, shape, tactile characteristics
    • Perceived Quality  100% inspection on outgoing products
  • Descriptive Statistics
    Objective
    Summarize data to be used for inference
    Pattern and Distribution
    Discrete  Binomial Distribution
    Variable  Normal Distribution
    Visual Representation

  • Control Charts for Variables
    Definition
    Purpose and Usefulness
    X-Bar Chart and R-Chart
  • Control Chart for Attributes
    Definition
    Purpose and Usefulness
    P- Chart and C- Chart
  • 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
  • Process and Measurement System Capability Analysis
    The Indices of Process Capability
    The processes and measurement systems considered
    Evaluation Criteria
    Results
  • 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
  • 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
  • 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
  • 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
  • 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
  • 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
  • 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
  • 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
