At any step in a project you can assign the current task and next task to another employee with the proper permissions. (See Employees Responsibilities and Permissions) 

As soon as a task is assigned to someone it will show up in their Dashboard and Projects screens letting them know that action needs to be taken. 

Once they have completed the task they can assign it back to the owner or another employee. There are two ways to do this:

1. Complete the current task using the green Action button and assign a different person for the next step as well as a due date. 

2. Reassign or Reschedule the current task to another employee and enter a different due date.
