A200SAM – Week 5
REVIEW OF THE LAST SEMINAR
Project initiation and definition
Project planning
WBS
Allocating and estimating time
Any questions?
WBS – diagrammatic view
Questions
What does the WBS help us to achieve?
Are there any drawbacks to the approach?
Project planning - 2
Activity
Using the handout worksheet, in pairs draw out the critical path for the activities.
What is the critical path for your project?
How much slack is there?
Be prepared to feedback.
Critical path analysis
Purpose
To calculate the longest sequence of dependent activities needed to complete the project
Use
Enables the PM to see the impact of delays/which activities can tolerate delays
Float highlights delay tolerance
Method
Two stages:
forward pass (earliest start)
reverse pass (latest start)

GANTT CHARTS
Another way of representing scheduling information
Intuitively easier to interpret than networks
Note that:
activities are arranged from top to bottom
time is plotted to scale from left to right
activity bars begin at their earliest start time
critical activities are highlighted
