Project Planning Software includes scoping, planning various aspects of project management, Recording , Monitoring, Closure. All activities (scope, time, cost, quality, risk, communication, procurement, integration & closure) which need to be completed within the start and end of the project are included in this software. It is an exhaustive exercise of creating a project plan from start till closure.

Project Planning Software is wrongly understood as the software which can help in recording start and end dates and owners and that's it. It is nowhere close to this. Ideal expectation is that, the software should follow all the principals of project management life cycle and have these as features implemented in the software. It should also help in making them automated as and where needed and take it to the lowest level of detail.

Size of the software varies from provider to provider. If you are looking for a specific need of starting-up for project planning with a software, you may want to try some of the open source software's listed on this website.
