Intervals
Intervals can be defined in Project properties in relation to
the time unit of the duration (such as hours or days).
You can choose among the following types of intervals:
- in absolute time (estimated duration including non-working
days, such as: 10 hours or 2 days)
- in calendar time (depending on the current calendar, that is,
it ignores non-working hours, such as: 3 working days)
- in relative time (for instance, a particular percentage,
relating to the "to" activity, such as: 50%)
Intervals can have
- positive (such as: + 2 hours) or
- negative (such as: - 50% = overlapping)
signs.
Highlight link
Links can be highlighted by means of colour or boldface.
