Differences between Tasks, Task-summary and Milestones?

Task:  Work specific development or description, may be assigned to teams, or have estimate effort or purchases and revenues added to it.

Task-summary: Groups previous tasks completed, the ITS team and effort will make up a large portion of it.

Milestone:  Reference point marking a major event in a project and used to monitor project progress, is dependent on the completion of the tasks predecessor.

THUS, when designing the project you will have to indicate a concrete manner of tasks and specify a set to achieve milestones. THEREFORE, it is necessary to take into account the following aspects:

• specify and list tasks to be performed;
• distribute time for development tasks, indicating start and end dates of each;
• sequencing tasks
