Table 3

If you changed the units on day two to 50%, you would end up with the following:

Day One – 50%

Day Two – 50%

Day Three – 36%

Contour One –42.94%

C2 – 100%

Contour Three – 50%

Contour Four – 56.5%

Table 4

Note that you now have four assignment contours of varying length.

All edits to the timescale segment are spread evenly throughout the segment. For example, if you assigned 50% units to a day and then changed the timescale to hours, you would see 50% units for each hour as well.

Other Possible Changes to Edited Contour Assignments

Adding a resource to a task with an edited contour assignment is not very different from adding a resource to a task with a predefined contour. The only difference that applies is the Usa value. For predefined contours, this is a fixed value. However, for edited contours, this value is calculated based on the following calculation:

 

Where Usa is the units’ scaled average, ∑Us is the sum of all of the segments’ units, and Ns is the number of segments. 

When segments are of unequal duration, Usa should be calculated as follows:

Where x is the segment number, Usx is the units of segment number x, Dsx is the duration of segment number x,  is the sum of all segments units multiplied by their segment duration  (THAT IS, ), and Da is the duration of the assignment.

Leveling

Leveling in Microsoft Project 2000 behaves very similarly to leveling in Microsoft Project 98. However, because of new feature enhancements, leveling has changed somewhat. It now takes into account some of the new features that have been added to Microsoft Project 2000. Before we take a look at which new features are related to leveling, let’s review what Leveling does in Microsoft Project.

Leveling in Microsoft Project

It is important to remember what Microsoft Project is doing when it is leveling. Although the end objective is to schedule resource work as efficiently as possible, we must remember that leveling does not change work or units on an assignment or task. Instead, when leveling makes a change, it does so by adding leveling delay or splitting work. These are the only ways in which leveling can make changes to a project. As we look at the new features related to leveling, this will become more obvious.

Microsoft Project 2000 Features Related to Leveling

There are only a few new features that are related to leveling. They are as follows:

Leveling From Current Schedule

If you’ve used Microsoft Project 4.x, you’ll be familiar with this option, which is a reintroduction of an old feature. Microsoft Project 2000 gives you the option to clear leveling values before leveling. This option is checked by default.
