Quality Management
     It is not enough to make sure you get
     it done on time and under budget – but
     it has to be of good quality

     Quality is a measure of how well your
     product does what you intend

     How closely your product meets the
     requirements

Scope

                                Time

Product Quality Attributes
    • Reliability - The probability of failure-free
      system operation over a specified time in a given
      environment for a given purpose
    • Availability - The probability that a system, at a
      point in time, will be operational and able to
      deliver the requested services
    • Safety - The system’s ability to operate,
      normally or abnormally, without danger of
      causing human injury or death and without
      damage to the system’s environment
    • Security – The system’s ability to protect itself
      from accidental or deliberate external attack


http://www.radiantminds.co.in
Product Quality Attributes
    • Efficiency
       – Software should not make wasteful use of
         system resources (disk and memory space,
         CPU time, etc.)

    • Usability (ease of use)
      – Software must be usable by the users for
        which it was designed

    • Dependability (reliability, availability, security,
      safety,…)

    • Maintainability (ease of maintenance)

Quality Management Process

     Quality Planning (Quality
     Management Plan)

     Quality Control (Monitoring and
     Controlling)

     Quality Assurance (Following Quality
     Standards)

     Pareto Charts

     Flowcharts

     Statistical Sampling

ISO 9000

    • International set of standards for quality
      management (ISO 9000:2000, ISO 9001:2000,
      ISO 9004:2000, etc.)

    • Applicable to a range of organisations from
      manufacturing to service industries

    • ISO 9004:2000 provides guidance for continual
      improvement of a quality management system to
      benefit all parties (employees, owners, suppliers,
      society in general,…)

http://www.radiantminds.co.in
ISO 9000 certification
    • Quality standards and procedures should be
      documented in an organisational quality manual

    • External body may certify that an organisation’s
      quality manual conforms to ISO 9000 standards
      (namely ISO 9001)

    • Customers are, increasingly, demanding that
      suppliers are ISO 9000 certified

The CMM and ISO 9000

    •   There is a clear correlation between the key
        processes in the CMM and the quality
        management processes in ISO 9000

    •   The CMM is more detailed and prescriptive and
        includes a more detailed framework for
        improvement

    •   Organisations rated as level 2 in the CMM are
        likely to be ISO 9000 compliant
