1. Developing a Project Plan Chapter 6 Luck favors to a prepared mind….. Louis Pasteur

2. Developing a Project Plan The biggest and important part of a project plan is establishing the project network

3. Project Network The project network is the tool for planning, scheduling and monitoring project progress. The project network presents a graphic display of the flow and sequence of work through the project Provides the basis for scheduling labor and equipment Provides an estimate of the projects duration Provides a basis for budgeting cash flow Highlights activities that are critical and should not be delayed Help managers get and stay on plan

4. Project Network The project networks are developed from the WBS

5. Project Network The project networks are developed from the WBS

6. Project Network The project networks are developed from the WBS

7. Project Network - Terminology Activity: an element of the project that requires time.Activity: an element of the project that requires time. Merge activity: an activity that has two or more preceding activities on which it depends.Merge activity: an activity that has two or more preceding activities on which it depends. Parallel (concurrent) activities: Activities that can occur at the same time if desired.Parallel (concurrent) activities: Activities that can occur at the same time if desired. A C BD

8. Project Network - Terminology Path: a sequence of connected, dependent activities.Path: a sequence of connected, dependent activities. Critical path: the longest path through the activity network that allows for the completion of all project-related activities;Critical path: the longest path through the activity network that allows for the completion of all project-related activities; C AB D

9. Project Network - Terminology Burst activity: an activity that has more than one activity immediately following it (more than one dependency arrow flowing from it) B D A C

10. Basic Rules in Developing Project Networks Networks typically flow from left to right.Networks typically flow from left to right. An activity cannot begin until all of its preceding activities are complete.An activity cannot begin until all of its preceding activities are complete. Arrows indicate precedence and flow and can cross over each other.Arrows indicate precedence and flow and can cross over each other. Looping is not allowed.Looping is not allowed.
