You should understand the differences between Mark for Action and creating tasks and
the best ways to use these features.
Mark for Action is part of the Marking feature and allows you to assign content items to
yourself for action, or invite others to review them and take ownership. Typically, you
should use Mark for Action in an informal, on-the-fly manner when you're discussing
something. For more information, see Using Marking feature.
Tasks are a formal way to assign and track tasks for yourself or others ( > Task or Actions > Tasks > Create a task). You can assign the task a deadline and associate it with a project, such
as Sales Kickoff January 2015, or save it as a personal task for yourself. All tasks that
are associated with a project are displayed on the Tasks tab of the project. For more
information, see Using projects and tasks.
