Primavera P6 duration issues – Hours per time period explained

Primavera is a wonderful tool but sometimes it’s calculations give weird results. For instance when filling in durations of an activity, you might’ve encountered a problem similar to the ones below:

  • Your activity duration is showing as 5 days but it starts on the 1st and already ends the 4th
  • Your units/time is showing 8h/d but Primavera is actually calculating with 12h/d

What is going on? Well it’s probably something to do with your hours per Time period settings.

Primavera P6 and the Longest Path

There is more to showing THE Critical Path in Primavera than your project manager can imagine. Primavera allows you to change certain settings to define the criticality of activities: you can define a threshold value for total float, or choose for the longest path instead of a total float-based critical path.

Correctly interpreting Activity Duration in Primavera P6

Duration and Calendar Duration, Time and Units/Time explained, P6 basic.

Time is of the essence. Both in project control and in our personal lives. As we’ve been dealing with time since childhood, you would assume we have learned to communicate on it effectively and unambiguously. But when someone says: “this activity is going to take 48 hours” you might take that as 2 days while he might’ve meant it will take two persons 3 8-hour-working days to complete.

Project Calendars over Global Calendars

Primavera P6 is designed as an Enterprise Project Portfolio Management (EPPM) tool. Even though often used as a standalone tool, Primavera P6 is a database initially designed for the enterprise’s needs where data can be shared between projects. In order to achieve this Primavera P6 uses the concept of “Global” data objects and “Project” (or embedded) data objects.

In this blog I will show you why using a project calendar over a global calendar for your project activities schedule is beneficial to maintain control over your project(s).
