Project Planning - Charter
The Project Charter
• Team’s response to the clients
statement of work (SOW)
• Sets the scope of the project
• It can include the following activities:
1. Write an Overview of the Project Scope
2. Determine the Team’s Boundaries for Creating
the Deliverables
3. Define the Customer’s Criteria for Acceptance

Project Planning - Charter
4. Determine the Required Reviews and Approvals
5. Establish Risk Limits
6. Select the Project Leader and Team Members
7. Set Deadlines for Delivery of the Final
Deliverables
8. Set Limits on Staffing & Spending
9. Create a List of Required Reports
10. Identify Organizational Constraints & Project
Priorities.

Project Planning - WBS
Work Breakdown Structure (WBS)
•“A deliverable-oriented grouping of project
elements that organizes and defines the
total scope of a project”
•Three to six levels in WBS’s, such as
program, project, task, and subtask.

Project Scheduling
Precedence Network
How can all the tasks of the WBS be
scheduled? One method is to start with
•Precedence Network
•Arrows showing order (precedence) of
the tasks
•Show only activity and resources

Project Scheduling
Class Activity
Establish the Precedence Chart for Building A
Habitat House
1. One activity per Post-It note, include name,
description and estimated duration (Initial
each Post-It).
2. Arrange Post-Its on chart paper
3. Work together to rearrange Post-Its in order
4. Draw arrows to indicate precedence

Project Scheduling - CPM
Critical Path Method builds on
Precedence Network
•A task number is assigned to each task
•The duration is indicated for each task
•The preceding task is identified for each
task from the precedence network
•Sum the activities along each path
•The critical path is the one of longest
duration

Project Scheduling - CPM
Forward Pass
Early Start (ES): Upper left corner of activity
•Add the earliest start of the activity’s latest
starting preceding activity to the predecessors
duration
•When two or more activities must be
completed the maximum is used
Early Finish (EF): Upper right corner of activity
•Add ES to duration for each activity

Project Scheduling - CPM
Backward Pass
Late Start (LS): Lower left corner of activity
Latest start of the earliest starting successor,
less the duration of the activity
Late Finish (LF): Lower right corner of activity
•Add LS to duration for each activity

Project Scheduling - CPM
Critical Path
•The path for which the Earliest and Latest
Times are identical.
•No delay of any event on this path can occur
without delaying the entire project.
•Non-critical elements that do not lie on the
critical path can be delayed some amount
without delaying the project.

Project Scheduling - CPM
Free Float
The amount by which an activity can be
delayed without any delay in the project.
Total Float
The total amount by which an activity can be
delayed without any delay in the project.

Project Scheduling
Class Activity
Use CPM for Building A Habitat House
1. Begin with Precedence Network
2. Calculate ES, EF, LS, LF for each activity
3. Determine the Critical Path

Project Scheduling – Gantt Chart
Gantt charts (aka timelines) show activities as
a function of time.
Each activity of the WBS occupies a row
Each week/month occupies a column
Duration of an activity indicated by horizontal
length
Interdependence can be included on Gantt
chart
Milestones are due dates or deadlines
