An efficient project management application must offer advanced planning features to allow the project manager to establish a detailed schedule with links between tasks and milestones materializing strong deadlines.
Project management software must also be an easy-to-use collaborative work tool to allow all users (occasional, contributors) to read the schedules, validate a task, enter a comment on a task and update their times.
Finally, communication and information sharing are essential factors for the success of a project. Project management solutions must offer elaborate and selective features that allow information to flow, without overwhelming users with an excessive flow of notifications.
