How to deal with short deadline while managing a project?

In my opinion planning and time management are the key to make it all work. Try to break large tasks into smaller manageable chunks, and make sure to attach deadlines to each task.

This is where your influence & persuasion skills come into play. If you squeeze the timeline, then something has to give - one or more of cost, quality, resource satisfaction or scope will get impacted.

It is always advisable as early as possible to understand which of the constraints is the most important to the customer - that helps in presenting options when such challenges emerge.

I also recommend wherever possible to prioritize scope delivery based on business value (taking into account risk and logical dependencies between activities) so that if you have to suddenly shave some time off the end date, you've at least delivered a reasonable percentage of the value of the project.

Many times the schedule tries to reflect the optimum track, but it is typical to have bumps in the road. Experience will help to more appropriately schedule tasks. That said if you see the schedule looks aggressive, raise awareness with rationale, potential pitfalls, and solutions. In the reverse, having to schedule aggressively against a timeline constraint, could look to crash or fast-track, reduce scope if possible, or divide the project into phased deliveries if possible.

You are most welcome, just keep in mind to get everyone involved and good communication plan in place.
