8. 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
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.

9. 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
Predecessor Table.
An alternative way of showing and analyzing the
sequence of project work is DSM * (Design Structure
Matrix).

10. Logic network and Planning
The logic network, also refereed to as precedence
diagraming, is the basic management tool for
controlling, monitoring, and distributing all resources
that 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 without
regard to particular construction preference.
One of the major uses of the logic network during
the planning stage is to indicate all activities that must
be 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.

17. Diagramma di Gantt
A popular bar chart that aims to show the timing of tasks or
activities as they occur across time.
Although the Gantt chart did
not initially show the relation-
ships between activities, this
has become more common in
current use as both timing and
interdependencies between
tasks can be identified.

20. 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.

23. Percorso critico/
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.
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.

27. 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 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.
