Project … is a planned undertaking
that has a beginning and an end and that produces a desired result or product • Organized activities • Defined (expected) outcome• Timeline, schedule
• SDLC (stages or phases and their sequence) • Methodology (models, techniques, tools,
guidelines)
activities &outcome

What is Project Management?
• …the process of planning, directing, and controlling the development of an acceptable system at a minimum cost within a desired time-frame
![Page 4: Lecture 6 24/9/15. Project … is a planned undertaking that has a beginning and an end and that produces a desired result or product Organized activities](https://reader036.vdocument.in/reader036/viewer/2022083009/5697bf821a28abf838c860b5/html5/thumbnails/4.jpg)
What does Project Management do?
• The classic SDLC must be monitored and managed• excessively long, drawn out process• leads to schedule and cost overruns
• Techniques such as FTS, JAD (Joint Appl. Dev.), prototyping, RAD (Rapid Appl. Dev.), and CASE • should be used to accelerate the life-cycle and • keep it under control within • the proven problem-solving framework of the SDLC
![Page 5: Lecture 6 24/9/15. Project … is a planned undertaking that has a beginning and an end and that produces a desired result or product Organized activities](https://reader036.vdocument.in/reader036/viewer/2022083009/5697bf821a28abf838c860b5/html5/thumbnails/5.jpg)
Features of a project• A start and a finish • Is a unique activity with a visible output• May involve uncertainty and risk• Involves a team coming together specifically for the
project• A budget• Non repetitive tasks, sequential order• Use of resources (including human resources)• A single point of ultimate responsibility• Clearly defined team roles• Clear aims, objectives, goals
![Page 6: Lecture 6 24/9/15. Project … is a planned undertaking that has a beginning and an end and that produces a desired result or product Organized activities](https://reader036.vdocument.in/reader036/viewer/2022083009/5697bf821a28abf838c860b5/html5/thumbnails/6.jpg)
Terms often confused with ‘project’• Process – a series of steps needed to perform a routine
activity (e.g. purchasing). A project may contain many processes.
• Programme – work performed towards achieving a long term goal (e.g. a health awareness programme). Programmes may never achieve all their goals, and may comprise a series of projects.

Examples of types of project and their size• Individual – decorating your bedroom• Group – organising a wedding• Organisation – construction company, building
the Millennium bridge in London• Project Organisation – creation of a separate
independent organisation specifically for accomplishing a particular project, e.g. the Olympic games committee• Multinational – design construction of Concorde

Why Project Management?
• Project mismanagement can deter or render ineffective the best analysis and design methods
• Many projects suffer from poor leadership and management
![Page 9: Lecture 6 24/9/15. Project … is a planned undertaking that has a beginning and an end and that produces a desired result or product Organized activities](https://reader036.vdocument.in/reader036/viewer/2022083009/5697bf821a28abf838c860b5/html5/thumbnails/9.jpg)
Four common results („symptoms”) of mismanaged projects
• Unfulfilled or unidentified requirements
• Uncontrolled change of project scope
• Cost overruns
• Late delivery

What can go wrong !
![Page 11: Lecture 6 24/9/15. Project … is a planned undertaking that has a beginning and an end and that produces a desired result or product Organized activities](https://reader036.vdocument.in/reader036/viewer/2022083009/5697bf821a28abf838c860b5/html5/thumbnails/11.jpg)
Causes of Failed Projects
• Unreasonable estimates of costs before projects begin• lack of proper preliminary/feasibility study• poor estimating techniques• estimates will change as the project progresses• schedule delays• analysts are overly optimistic
![Page 12: Lecture 6 24/9/15. Project … is a planned undertaking that has a beginning and an end and that produces a desired result or product Organized activities](https://reader036.vdocument.in/reader036/viewer/2022083009/5697bf821a28abf838c860b5/html5/thumbnails/12.jpg)
Causes of Failed Projects
• Mismanagement of expectations • failure to identify key (or all potential) stakeholders • failure to set project scope leads to
creeping requirements syndrome • budgets and schedules rarely modified
• Most contemporary companies modify (release) content

Causes of Failed Projects• Misunderstanding the nature of software • Flexible • No real physical appearance – only behaviour
• you can not touch a software component • `you may see the code and the result what it does (or not)• Difficult to estimate
=> Mythical man-month• assign more people to the project team
• Only leads to more confusion • Complexity increases on the management side
