  1. Project Management Methods By Dr. Baker Abdalhaq

  2. Introduction • Software developers systematically fail to manage projects. • Solutions have been developed during the past 35 years. • Still, in practice not much has changed.

  3. A typical "waterfall" model

  4. Project stages • Why have stages? • Break a large problem down into smaller, more manageable problems • A tool for monitoring progress • Has project kept to plan so far? • Are there any problems? • Points at which senior management assess project viability: • Will it deliver on-time and stay within budget? • Will it achieve what we want? • Is corrective action needed? • Management authorisation to proceed with next block of work • Concentrates the mind • Project team members do not want to be the cause of holding up the end of a stage

  5. Project stages • How do you decide what stages a project should have? How many? How long? • How do you even know what tasks are needed in a project?

  6. Waterfall approach • Software development has gradually evolved from unstructured to structured, both in producing programs and in managing projects • The waterfall approach assumes all requirements are written down before producing them. Each definition is "signed off" by the user before starting work • Project definition signed before starting project • Systems analysis agreed before starting design • Design agreed before starting programming, and so on • Advantages: Planned duration, responsibility pinned down, orderly, should result in few corrections late in project

  7. Waterfall approach

  8. It can be difficult to state when a stage is complete, ie. we may have to correct to previous work • Causes of failure once a project has started: • 74% Unclear objectives and requirements • 60% Lack of business commitment • 58% Business requirements changing • 45% Poor communication • "No-one knows what they want until you give them what they ask for" (Gerry Weinberg)
