PROJECT MANAGEMENT
Defined as the processes required ensuring timely completion of a project. Involves the following processes: A. Activity Definition B. Activity Sequencing C. Activity duration estimating D. Schedule development E. Schedule control
A. ACTIVITY DEFINITION
Results in the project team developing a more detailed WBS and supporting explanations Ensure that the project team has complete understanding of all the work they must do as part of the project scope
B. ACTIVITY SEQUENCING
Involves reviewing the activities in the detailed WBS, detailed product descriptions, assumptions, and constraints to determine the relationship between activities Involves evaluating the reasons for dependencies and the different types of dependencies Dependency Also called relationship, shows the sequencing of project activities or tasks
B. ACTIVITY SEQUENCING
Reasons for creating dependencies: Mandatory dependencies – (hard logic), inherent in the nature of work being done on a project Discretionary dependencies – are defined by the project team External dependencies – involve relationships between project and non-project activities
PROJECT NETWORK DIAGRAMS
The preferred technique for showing activity sequencing Schematic display of logical relationships among, or sequencing of project activities Uses the activity-on-arrow (AOA) or the arrowdiagramming method (ADM)

PROJECT NETWORK DIAGRAMS
Steps in creating an AOA Network Diagram Find all of the activities that start at Node 1. Draw the finish nodes, and draw arrows between Node 1 and each of those finish nodes. Put the activity letter or name of the associated arrow. If you have a duration estimate, write that next to the activity letter
