  1. COMP2001 HNC Project

  2. Project Characteristics • A project must have: • clear objectives • planning & control • resources • assurance of quality

  3. Project Definition A project is defined in terms of its: - background - objectives - scope - constraints

  4. Project Schedule • Determine project approach (buy or build) • Estimate effort • Prepare project plan • Prepare project budget • Document project progress

  5. Project Schedule • Time ordered sequence of deliverables • Used for: • organising work effort • working towards project goals & obj. • tracking the project

  6. Tasks • Smallest unit of work • Each task only occurs once • Suitably described • Enough details to be measurable

  7. Milestones • Point in schedule to measure progress • Contains a sequence of tasks

  8. Project Management Techniques • Traditional project management techniques widely used in many other industries. • These include:- • Work Breakdown Structure (WBS). • Gantt chart. • PERT chart (critical path or network diagram).

  9. Work Breakdown Structure • Very useful for initial planning. • Helps identify required resources. • Structured list of all tasks and activities that must be carried out to complete project. • Usually, sequence is unimportant. • Main purpose is checklist for completeness.

  10. WBS example: “clean bedroom” hoovering • get hoover • move furniture • hoover floor dusting • get duster • move ornaments • do dusting change bed, etc.

  11. Gantt Chart • The classic “bar-chart”. • Often based on WBS, but includes time dimension. move furniture get hoover hoover floor put furniture back put hoover away time

  12. PERT Chart or Critical Path Chart • “Programme Evaluation and Review Technique”. • Designed to show interdependencies between tasks: • “get hoover” must be complete before “do hoovering” starts (i.e. B depends on A); • “move furniture” can happen before or after “get hoover” (no dependency). • Often derived directly from Gantt Chart.

  14. Resource Levelling • First-cut chart is not always the most efficient. • It may be possible to: • reduce overall resources required, • reduce total project time. • “Levelling” means: • use available float time on non-critical tasks, • move spare resources from one task to another. • A matter of judgement - no one best way.
