Durations and Progress

Durations and Progress

Here we will describe how project and phases duration and progress are calculated and what are their meanings.

Project Duration and Progress

• Normal

  

• Delayed

  

Actual duration

58 is Actual Duration (or current duration) - it is calculated using all active and completed phases:

• it includes delayed time for active phases
• doesn't include overlapped time twice
• include gaps between phases

Planned duration

65 is Planned Duration - it is calculated using all non-draft phases:

• doesn't include overlapped time twice
• include gaps between phases
• so basically it's difference between minimum startDate of a phases till maximum endDate of phase (which are non-draft)

Delay duration

14 is Delay duration - it is calculated as a difference between Actual Duration and Planned Duration.

Project Progress

53% is Project Progress - it is calculated as average progress of all non-draft phases.

Example, if we have:

• Planned phase (progress 0)
• Active phase with progress 17%
• Completed phase (progress 100%)
• Drast pahse (is not included in calculations)

Then Project Progress would be (0 + 17 + 100 / 3 = 39%).

Methods

Gaps betwen phases

Imagine we have 2 phases with a gap between them:

• Sep 1 - Sep 3 (3 days)
• a gap
• Sep 5 -Sep 7 (3 days)

The total project duration is calculated since Sep 1 till Sep 7 (8 days) including the gap, rather than just sum phases times.

Overlapped time

Imagine we have 2 phase which overlap each other:

• Sep 1 - Sep 7 (8 days)
• Spe 4 - Sep 11 (8 days)

The total project duration is calculated since Sep 1 till Sep 11 (12 days) and doesn't calculates overlapping time twice.
