ISO 9000 series
ISO 9000 series stems from early DoD Quality
Standards issued in the 50s.
1959, DoD Std, with a wider field of application
to include the whole organisations process, were
adopted by British Standard Institution as BSI
5750.
1987, l'International Organization for
Standardization adopted BSI 5750 as ISO 9000
series.

ISO 9000 series
In Europe, CEN (European Standard
Committee) adopt ISO 9000 Stds as EN ISO
9000
Each National Body for Normation adopts the EN
ISO standards, possibly by translating them in
the national language.

Organizations have a grace period of 3 years to
modify their own Quality Management Systems in
accordance with the new ISO 9001 2000

ISO/IEC 12207 - Software life cycle processes

• What is ISO/IEC 12207?
• a standard for facing the babel in software
  management and engineering that provides a common
  framework to speak the same language in software
  discipline

• specific development methods to be adopted

13
ISO/IEC 12207 - Software life cycle processes

• The standard establishes a comprehensive set of
• processes
• activities
• tasks
• constituting a common framework for software life
