    OPERATIONS MANAGEMENT

    QUIZ 1
    Buan, Jamilah Marie M.
    BSBA IV – 4
    Instructions:
    1. Draw the diagram of the 7 basic tools of quality
    2. Define each stage
    3. Explain each stage with example.

    1. Stratification
    It is a quality assurance
    technique for classifying the data,
    objects, and people into separate
    groups. Using stratification to divide
    your data might help you establish its
    significance, exposing patterns that
    would not otherwise be visible when
    it is grouped together.

    2. Histogram
    Illustrates the frequency distribution
    of data among separate groups of a sample
    in a clear and concise manner, allowing you
    to easily and effectively discover areas of
    improvement within your processes.
    Histograms are very useful for classifying
    the frequency of your data, such as age,
    days of the week, physical measures, or any
    other category that may be displayed in
    chronological or numerical order.
    3. Check Sheet (or Tally Sheet)
    Used for gathering
    quantitative or qualitative data.
    A check sheet gathers data in
    the form of check or tally marks
    that show how many times a
    given value has happened,
    allowing you to rapidly zero in
    on errors or mistakes within your process or product, defect patterns, and even
    particular defect causes.
    4. Cause-and-effect
    diagram (Ishikawa or
    fishbone diagram)
    The fishbone
    diagram, created by Kaoru
    Ishikawa, helps users in
    identifying the many
    variables (or causes) that
    result to an effect, which is
    typically presented as a
    problem to be solved. The causes and subcauses of a fishbone diagram are often
    classified into six major groups: measurements, materials, personnel, environment,
    techniques, and machines.
    5. Pareto Rule (80 – 20 rule)
    This rule assumes that in
    any process, 20% of major
    factors, commonly referred to as
    the "vital few," create 80% of the
    process's or system's issues.
    The remaining 20% of issues are
    caused by 80% of minor causes.
    The Pareto chart's goal is to emphasize the relative significance of various
    parameters, helping you to identify and focus your efforts on the elements that have
    the greatest influence on a specific area of a process or system.
    6. Scatter Diagram
    The most helpful in showing the
    connection between the two
    variables, making it appropriate
    for quality assurance
    professionals attempting to
    discover cause and effect
    correlations. When used to
    define relationships between
    quality problems and possible
    reasons such as environment, activity, personnel, and other variables, scatter
    diagrams may be useful as a quality control tool.

    7. Control chart (Shewhart chart)


    This quality improvement
    method, named after Walter A.
    Shewhart, can help quality
    assurance professionals in
    determining whether or not a
    process is stable and
    predictable. Control charts show
    an average or mean by using a
    central line, as well as upper
    and lower control limits based on historical data. By projecting process performance,
    a control chart may save your company time and money, particularly in terms of what
    your client or organization expects in your end product.
