Project Scheduling

Project, objectives, tasks and activities are now defined but:

  • Need to define PRECEDENCE RELATIONSHIPS of the activities

Questions to ask:

  • Which activities are you going to start with?
  • Which need to wait for the completion of another?
  • Which tasks need to be completed simultaneously?

The sequencing of activities are influenced by:

  • Technical requirements
  • Efficiency
  • Availability of resources
  • Policies

Scheduling Tools

  • Gantt Charts
  • Bar Chart

Each activity is assigned a number, and time is plotted along the horizontal axis. This kind of chart was developed by Henry Gantt during WWI.

Gantt Charts are useful because:

  • Easy
  • Indicate the status of each activity
  • Allow tracking of progress.
  • Allow for what–if analysis
  • Can be drawn to show budgets, needed resources, and equipment usage instead of activities.

However Gantt Charts:

  • do not show precedence relationships
  • are at times tedious to update

Example of a Gantt Chart:

Task Name Week Number
6 7 8 9 10 11
Literature review on Surveys
Prepare Survey
Test Survey
Choose a Stat software
for analysis
Administer Survey

Project Networks

A pictorial representation of the activities and their precedence relationships.

Are made up of nodes and arcs

Arcs represent the activities

Project Duration: 12 weeks (Longest path)

The longest path is called the critical path
Activities a, d, f, g, h, j are the critical activities
