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
The Term Paper on Complexity Measurement of a Project Activity
Further researchers developing a metric for overall cycle time effectiveness for concerted productivity improvement efforts in the service sectors also holds a similar view as what gets measured gets done and improved. However, there is no standard approach to measure service performance as each industry is unique [7]. Due to the unavailability of acceptable quantitative metrics, most companies do ...
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) A=1 1 B=2 2 3 4 G=6 D=4 E=5 5 F=4 H=6 6 I=2 J=3 8
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 or name. Make sure to put arrowheads on all arrows to signify the direction of the relationships Continue drawing the network diagram, working from left to right. Look for bursts and merges.
PROJECT NETWORK DIAGRAMS
Continue drawing the network diagram until all activities are included on the diagram As a rule of thumb, all arrowheads should face toward the right, and no arrows should cross on an AOA network diagram. Precedence Diagramming Method (PDM) A network diagramming technique in which boxes represent activities
PROJECT NETWORK DIAGRAMS
Types of dependencies between activities Finish –to- start: a relationship where the “from” activity must finish before the “to” activity can start Start –to- start: a relationship where the “from” activity cannot start until the “to” activity can start Finish –to- finish: a relationship where the “from” activity must finish before the “to” activity can finish Start –to- finish: a relationship where the “from” activity must start before the “to” activity can finish
