analyse project management softwares

Claudio,

Your list is broad in terms of versatility where Intervals is more focused on time, task and project management and how the three intertwine during the project workflow. That said, Intervals does have some of the items from your list:

E-mail
Intervals utilizes email in two ways. One, email notifications are sent out by various system events. For example, updating a task will email notifications to the assignees. Second, Intervals is able to read in emails from an email server and create tasks from them. This can be helpful for fielding requests from clients and assigning the requests as tasks.

Personal description
All users have a personal profile for storing information such as email, phone number, and web site address. In the upcoming month we'll be adding multiple contact profiles to the clients section for keeping track everyone.

File sharing
Yes, Intervals does support document uploading and sharing. Documents can be upload to a task or a project and will be shared with others who have access to the same projects.

Gantt chart
Intervals has what we call the Periscope Report. This is a Gantt-like chart used to view projects along a timeline. we'll soon be updating it with tasks and milestones so that project managers can see scheduled work along the same timeline. This will help allocate resources to current projects and help know when to schedule new projects.

Regards,
John
