  1. SOFTWARE LIFE-CYCLES Elements and Definitions

  2. Life CycleANSI / IEEE Std 729-1983 • A life-cycle is • a period of time that • starts when a software product is conceived and • ends when the product is no longer available for use. ==> Organised in phases

  3. Phases of a Life-Cycle • Requirements • System Design • Detailed Design • Implementation • Testing & Installation • Operations & Maintenance • Retirement

  4. A phase is a • period of time within a life-cycle • that has a defined goal and • is based on result(s) of earlier phases.

  5. Phases are activities • that transform inputs into outputs and • interact so that the transformation goes • from abstract needs to • correct source-code. ==> results (= inputs & outputs): documents ==> verify transformations at milestones

  6. Documentation • internal technical documentation • external technical documentation • end-user documentation • for each version and release ==> supported by standards

  7. internal technical documentation: • the results of each phase • the rationale and assumptions behind the decisions made in each phase • layouts and results of tests • error & fixes log

  8. external technical documentation: • system structure • required environment • instructions for installation • maintenance & operation • guidelines for trouble shooting

  9. end-user documentation: • user handbook • quick reference • guided tour • standard set-up

  10. Milestone • A scheduled event • for which some project member or manager is accountable and • that is used to measure progress.

  11. A milestone includes typically • - a formal review, • - the issuance of documents and • - the delivery of an (intermediate) product. ==> supported by standards

  12. Standards • Project independent • rules and procedures • embedded in a common system of terms • and quality criteria • that ensure inter-project adaptability • and compatibility of solutions. • Important organisations: ANSI, IEEE

  13. End of Section 1b coming up: alternatives to the waterfall model
