Since we established the list of activities involved in our project, we can set a deadline for some tasks. Deadline dates are a handy way to alert you to problems in your schedule, but they are often overlooked. If you want a task to start or finish on a certain date but want to retain the flexibility of the schedule, you can enter a deadline date.
A deadline is a target date indicating when you want a task to be completed. Imposing an inflexible constraint such as Must Finish On, that sets the finish date can lock up your schedule in ways you don't want. Instead, if you just need a reminder, you can use the deadline field of a task. This will create a green downward arrow on the Gantt chart, that marks the deadline date. The advantage of deadlines is that they keep track of its finish date without locking the schedule.
If the finish date of a task passes the task deadline, a warning icon will be shown in the Indicators column.
To set a deadline for a task, open the Task Information dialog corresponding to it, go to Advanced tab and
next to Deadline, fill in your deadline date.
Apply a deadline to a task when you want to track a deadline for a specific task, but don't want to lock your schedule by setting an inflexible constraint such as Must Finish On or Finish No Later Than. Such constraints affect scheduling, while the Deadline field simply causes an indicator to show if a task has not been completed by its deadline. Certain tasks in your project should finish by specific target dates. However, you don't want these dates to actually affect how Project Plan 365 schedules the tasks; you just want to be alerted if the tasks are not completed by these dates. Add the Deadline field to the Entry table of the Gantt Chart view, and set the deadline dates for these tasks.
By setting a task deadline, instead of imposing an inflexible constraint for a task to mark its finish date, you can achieve a more flexible and dynamic project schedule. A dynamic schedule is properly sequenced and is free of any task constraints. The benefit is that the project manager can assess changes to the project end date (via the critical path) without experiencing constraint errors.
Deadlines can be added to any task in the project schedule. You may want to add specific deadlines based on the tasks on the critical path or on important milestones. The deadline gives you flexibility in setting a commitment date that isn’t tied directly to a baseline finish date.
1. Let's consider the task with ID = 30 (Excavate foundations), which has set a Must FInish On constraint. However, this might not be the right choice, given the fact that this is an inflexible constraint, which reduces the flexibility of your schedule and tells Project Plan 365 that this task must finish on that date and not before.
A better approach is to let Project Plan 365 to handle start date with As Soon As Possible constraint and put the deadline information about the task, as a replacement for the Must Finish On constraint and the associated constraint date. For this, let's open the Task Information dialog for this task and then head to the Advanced tab. Here we will indicate 13 December 2016 as the deadline date and change the constraint type to As Soon As Possible:
Also we will enter 24 in the Predecessors cell of this task. This is what you should get. Notice that in the Indicators column the icon corresponding to Must Finish On constraint is no longer shown.
2. Once the deadline is set for the task, we will get the Deadline indicator in our Gantt diagram, marking the deadline date:
3. Notice how this change affects the duration and the finish date of the project.
4. Now, let's suppose that we want to track the deadline for the task called Pour column piers and foundations. Open the Task Information dialog for this task, go to the Advanced tab and next to Deadline, fill in your deadline date. Let’s say 7th of November.
Once the ‘Deadline’ is set, it shows up on the Gantt chart as a green arrow marking the ‘Deadline’ Date. Since the finish date of the task passes the task deadline a warning icon will be shown in the Indicators column.
If you hover over the indicator, it informs you that the task goes past its deadline.
5. You can also add the Deadline field to a task sheet when you want to enter, view, or change the deadlines of tasks in your project. To achieve this, select Predecessors column, press on the Insert Column option under Format menu and select Deadline from the list:
Once you press OK in this dialog, the Deadline column will show up in the task grid. You can notice the deadline values that we've set for the two tasks in our project.
, hide this column since we will no longer need it.
