PROJECT MANAGEMENT

1
PROJECT MANAGEMENT

• Outline
• What is project mean?
• Examples of projects
• Project Planning and Control
• Project Life Cycle
• Gantt Chart
• PERT/CPM

2
What is Project?

• What is the different between normal business
  activities and Project?
• Project
• Unique, one time operations design to
  accomplish a specific set of objectives in a
  limited time frame.

Examples of project

1. Building a house
2. Building a factory
3. Add assembly line in the factory
4. Merging to companies
5. Managing political campaign
6. Designing a new product
7. Soft ware development

Work Breakdown Structure

• What are the tools?
• Work breakdown structure
• Network diagram
• Gantt charts
• Risk management

6
Key Decisions

• Deciding which projects to implement
• Selecting a project manager
• Selecting a project team
• Planning and designing the project
• Managing and controlling project resources
• Deciding if and when a project should be
  terminated

PERT and CPM

• PERT Program Evaluation and Review Technique
• CPM Critical Path Method
• Graphically displays project activities
• Estimates how long the project will take
• Indicates most critical activities
• Show where delays will not affect project

10
The Network Diagram

• Network (precedence) diagram diagram of project
  activities that shows sequential relationships by
  the use of arrows and nodes.
• Activity-on-arrow (AOA) a network diagram
  convention in which arrows designate activities.
• Activity-on-node (AON) a network diagram
  convention in which nodes designate activities.
• Activities steps in the project that consume
  resources and/or time.
• Events the starting and finishing of
  activities, designated by nodes in the AOA
  convention.

11
The Network Diagram (contd)

• Path
• Sequence of activities that leads from the
  starting node to the finishing node
• Critical path
• The longest path determines expected project
  duration
• Critical activities
• Activities on the critical path
• Slack
• Allowable slippage for path the difference the
  length of path and the length of critical path

Questions answered by PERT/CPM

• When will the entire project be completed?
• What are the critical activities or tasks in the
  project, that is, the ones that will delay the
  entire project if they are late?
• Which are the non-critical activities, that is,
  the ones that can run late without delaying the
  entire projects completion?
• What is the probability that the project will be
  completed by a specific date?

16
Questions answered by PERT/CPM

• At any particular date, is the project on
  schedule, behind schedule, or ahead of schedule?
• On any given date, is the money spent equal to,
  less than, or greater than the budgeted amount?
• Are there enough resources available to finish
  the project on time?
• If the project is to be finished in a shorter
  amount of time, what is the best way to
  accomplish this at the least cost?

17
To Find Critical Path ???

• To find the critical path, need to determine the
  following quantities for each activity in the
  network
• 1. Earliest start time (ES) the earliest time an
  activity can begin without violation of immediate
  predecessor requirements.
• 2. Earliest finish time (EF) the earliest time
  at which an activity can end.
• 3. Latest start time (LS) the latest time an
  activity can begin without delaying the entire
  project.
• 4. Latest finish time (LF) the latest time an
  activity can end without delaying the entire
  project.
