Tim --
Your question is a good one, however, I think my original answer to your
question got "swallowed" by the newsgroup server this afternoon (Wednesday),
so I'll give it another try.
When you plan a project, the Start date for each task is the "planned" start
date. When you save a baseline for the project, this "planned" start date
is captured for each task and placed in the Baseline Start column.
When work is performed on a task, Microsoft Project 2002 calculates an
Actual Start for the task based on the information you enter. At that time,
the Start date for the task is set to match the Actual Start date. So,
you're probably thinking, "But my planned Start date is lost!"
That's not the case at all. Remember, your "planned" Start date for each
task is stored in the field called Baseline Start. You can examine this
value in your project, and even see slippage on each task, by doing the
following:
1. Apply the Tracking Gantt view
2. Click View - Table - Variance
3. Pull the vertical split bar all the way to the right so that you can see
all the columns
Notice the columns called Baseline Start and Start Variance. The Start
Variance column tells you whether your tasks are on schedule, behind
schedule, or ahead of schedule against your original baseline (planned)
schedule. If Start Variance is a positive number, your task is starting
late, and if it is a negative numer, the task is starting early. Hope this
helps.
