Let me tell you this story of a project manager; he spent
time with his team to compile their project planning, then proudly print it on
A0 page, and pin it on the wall behind his desk. This is for me one of the most
common mistakes a beginner does on project management. Why? Because the time
you print the schedule and pin it on the wall, the schedule is not anymore up
to date. You planning is alive, people will make work and progression on some
tasks, others tasks might be delayed… It is important to track the work done in
order to answer the question “how are we progressing compared to original
plan?”.
A snapshot of the original plan should be saved in order to
allow later comparison. This is what we call the Baseline.
Once your original planning is done, you can save your first
baseline, by clicking on Project
> Set Baseline > Set Baseline.
Select the baseline you want to set. Note that 11 baselines
can be saved (baseline, then baseline 1 to baseline 10). As this is the first
time you set a baseline for this project, ensure you set baseline For: Entire Project.
When a baseline is saved, the application takes a snapshot
of the following fields (
all fields’
definition can be found on support.office.com):
- Project start and end date
- Work and duration
- Cost
- Budget Cost, Budget work
- Deliverable start and end date
- Fixed cost and fixed cost accrual

Baseline (somehow Baseline
0) is used as the current baseline, which means that when the scope change
after an approved Change Request, the baseline is updated. I order to keep a
version of the original baseline of the project, it is recommended to set Baseline AND Baseline 1 at the same time when you first set a baseline. By
doing this, you will be able to compare current situation with current
baseline and with initial baseline. Use Baseline
2 to Baseline 10 the same way
for important scope change you want to compare later on with current
situation.

Set an interim
plan
Compared to a baseline, an interim plan only save two elements: a start date and a finish
date. You can choose to copy current start and finish date or any of the
baseline start and finish date.
Update your
baseline
The only
case where you have to update your baseline, is when there is an approved scope change. Let say,
you add another task to your schedule. In this case you just need to update the
desire baseline with the new task.
Select the new task(s) (and subtasks if any), you want to
add to the baseline. Click Project
> Set baseline > Set Baseline. Select the baseline you
want to update. Under For:, click Selected tasks.
If you are adding subtasks to your baseline, under Roll up baselines:, you can choose
among these two options to specify how subtasks interact with their summary
tasks.
- To all summary tasks Updated baseline data for the new tasks is rolled up to all associated summary tasks, not just the nearest summary task.
- From subtasks into selected summary task(s) Baseline data is updated only for the selected summary task. Typically, you’ll do this so that only the nearest summary task reflects the new roll‐up data.

Track percent
complete for tasks
Once baseline is set, you can start tracking the work done. We
will consider here two ways to add actuals (work done) to your planning:
1) By using % complete buttons
Select a task, click on the Task tab on the ribbon, on the Schedule
section, you will find the % complete buttons.
Easy to understand, you can set your percentage of
completion for your task by clicking on one of these buttons. You can only use
these buttons when your progression is as planned (if you click on 75%, it
means that 75% of your task is done and 25% of your task is remaining).
2) By entering actual work and remaining work on
the task form
Doing this will allow you to enter 1) actual work and 2) remaining
work. Here, you will be able, for example for a task of 2 days, to say that you
already worked 2 days, but you will need another day to complete the task,
meaning that the total work will be 3 days, more than initially planned.
To do so, you need to use the split view and
display Task Form with work table. On the View
tab, check Details and select Task Form.
Once
the task split view is displayed at the bottom of your screen, right click on the right side in order
to select the Work table.
You will then be able to enter the values for Task 1, Actual work is 2
days and remaining work is 1 day. The
updated work becomes 3 days, where baseline work was 2 days. Click Ok to save.
Display your
baseline using Tracking Gantt view
The Tracking Gant view displays your actual schedule and the
baseline schedule.
On the Task tab,
click on the view selector and choose, Tracking
Gantt.
You can also add the baseline to your current Gantt view
(non-tracking mode). On the Gantt Chart
Tool > Format ribbon, click
on Baseline and select the baseline
you want to display.
On the Gantt chart, you will see actual work, remaining work,
% complete and the baseline.
Manage your
project by measuring variances and work with Earned Value Management
Because for each task you can enter new workload, new start
and finish date, now you can measure variances (compared to the baseline):
- Start variance, being the difference between actual start date and baseline start date
- Finish variance, being the difference between actual finish date and baseline finish date
- Duration variance, being the difference between actual duration and baseline duration
- Work variance, being the difference between actual work and baseline work
- Cost variance, being the difference between actual cost and baseline cost
Thanks for those valuable informations. I am conflicted on how to create a baseline for a project. Which of the following scenarios would be considered a "best practice" for creating a project baseline in which to measure progress and get some schedule-related EVM metrics? Is Primavera Really usefull for this process, What you did was exactly what I suggested???
