Project Network

� A project network is a graph (flow chart) depicting

the sequence in which a project's terminal elements

are to be completed by showing terminal elements

and their Product Breakdown Structure show the

"part-whole" relations. In contrast, the Project"part-whole" relations. In contrast, the Project

Network shows the "before-after" relations.

� The most popular form of project network is activity

on node, the other one is activity on arrow.

� The condition for a valid project network is that it

doesn't contain any circular references.

8

Predecessor Table & DSM

� The activity network diagram technique emerged as the Program Evaluation Research Technique (PERT) and as the Critical Path Method (CPM) in the 1950s. There are several ways to represent the output of the PERT/CPM process.

� Project dependencies can also be depicted by a � Project dependencies can also be depicted by a Predecessor Table.

� An alternative way of showing and analyzing the sequence of project work is DSM * (Design StructureMatrix).

Logic network and Planning

� The logic network, also refereed to as precedencediagraming, is the basic management tool forcontrolling, monitoring, and distributing all resourcesthat are directly related to time.

� The logic network at the planning stage is a pure dependency diagram. All activities are drawn in the order in which they must be accomplished withoutorder in which they must be accomplished withoutregard to particular construction preference.

� One of the major uses of the logic network duringthe planning stage is to indicate all activities that mustbe accomplished to complete a particular project.

� As a general rule, an activity should be created for any function that consumes or uses direct labor resources.

Diagramma di Gantt

16

Diagramma di GanttA popular bar chart that aims to show the timing of tasks or

activities as they occur across time. Although the Gantt chart didnot initially show the relation-ships between activities, thishas become more common in current use as both timing and interdependencies betweentasks can be identified.

Relazione tra attività

Per avere la massima rispondenza con la modellazione dei processi le relazioni di interdipendenza temporali sono:

Le relazioni sono ulteriormente modificabili con l’introduzione di ritardi, o anticipi, rispetto al predecessore.

Critical Path

� The critical path is the sequence of activities that must be

completed on time for the entire project to be completed

on schedule.

� It is the longest duration path through the workplan. � It is the longest duration path through the workplan.

� If an activity on the critical path is delayed by one day, the

entire project will be delayed by one day unless another

activity on the critical path can be finished a day earlier

than planned.

Project Baseline

� A baseline is an approved configuration item, for

example a project plan that has been signed off for

execution.

� The baseline records the schedule, the planned

resources, the planned costs, and technical requirementsresources, the planned costs, and technical requirements

against which a project is measured. Data including:

� Tasks: Duration, Start and Finish dates, work,

timephased work, cost and timephased cost.

� Resources: Work, timephased work, cost, timephased

cost, budget work, timephased budget work, budget

cost and timephased budget cost.
