Website Upgrade Incoming - we're working on a new look (and speed!) standby while we deliver the project

Tips on using this forum..

(1) Explain your problem, don't simply post "This isn't working". What were you doing when you faced the problem? What have you tried to resolve - did you look for a solution using "Search" ? Has it happened just once or several times?

(2) It's also good to get feedback when a solution is found, return to the original post to explain how it was resolved so that more people can also use the results.

Duration Variance (task field)
Data Type Duration

Entry Type Calculated

Description The Duration Variance field contains the difference between the baseline duration of a task and the total duration (current estimate) of a task.

How Calculated The Duration Variance field contains "0 days" until the duration value varies from the baseline duration value, as shown in the Baseline Duration field. Microsoft Office Project 2003 then calculates duration variance as follows:

Duration Variance = Duration - Baseline Duration

Best Uses Add the Duration Variance field to a task sheet when you want to analyze whether your schedule is taking more or less time than originally planned.

Example You set a baseline for your project three months ago, and you now want to review duration variances for the tasks. You add the Duration Variance field to the Task Sheet view to analyze the project’s progress and performance to date.

Remarks If the duration variance is a negative number, the task is scheduled to take less time than originally planned. If the duration variance is a positive number, the task is scheduled to take more time than planned. If the duration variance is zero, the task is taking exactly as much time as originally planned.

The Duration Variance field contains "0 days" until the duration value varies from the baseline duration value, as shown in the Baseline Duration field. To set a baseline, point to Tracking on the Tools menu, and then click Save Baseline. This copies the current value for the scheduled Duration field into the corresponding Baseline Duration field.

You can use the Tracking Gantt view to see the duration variance shown graphically with Gantt bars.
