  4. The design life cycle (Donald's gross over simplification) • Need/idea • Overview/plan • Need specification • Requirements analysis • Design • Build • Run • Maintain • Improve • Decommission

  5. A typical version • Initiation/Planning • Requirements Gatherings And Analysis • Design • Build or Coding • Testing • Operations and Maintenance

  6. Why • Need to manage complexity • Large projects (LUL) • Numerous stake holders (LUL) • `Need to check resource viability (before, during am after (Nimrod, Olympics, Dome) • Usability • Sustainability • Environmental issues
