Metrics are important
tools used in modern software engineering of large IT
projects. They provide in advance essential information
to help knowing whether the project is heading to the right
direction or to detect in time needed adjustments. However,
collecting metrics is not necessarily an easy task.
In this presentation,
a general overview of what metrics can provide will be
given, together with a description of different approaches
to collect them. I addition a schematic classification of
the existing standards will be provided.
