Project:  a series of activities directed to the accomplishment of a desired objective.

Difficulties encountered:

  • many projects are non-repetitive
  • prior information to control the project is sparse, non-existent or           
only marginally relevant.

Project control techniques then require:
  • Planning to determine a logical (preferably optimal) project plan
  • Execution evaluation
  • Control capability

In engineering projects:

  • Many interdependent activities are required
  • Some activities must be executed simultaneously
  • Some cannot be performed until other activities have been completed or events have occurred
  • Each activity will require resources in personnel and equipment


Terms

Network path:  a sequence of connected activities that runs from the start node to the end node in the network.

Critical Path:  the longest path through a network the minimum project completion time.


GANTT Chart

A graph or bar chart with a bar for each project activity that shows the passage of time.

Traditional management technique used for:

  • scheduling and planning
  • small projects
  • projects with relatively few activities and precedence relationships

Helps to identify areas where there is slack

      "the amount of time an activity can be delayed without delaying the project"

This visual display of the project schedule indicates:
  • when activities are scheduled to start
  • when they should be finished
  • where extra time is available
  • the precedence relationships between activities

Difficulties encountered:
  • Precedence relationships are not easily discernible
  • limits chart's use to smaller projects with relatively few activities
