Setting Duration for activities helps you plan better and always know how much time you have to execute a step before a project ends.
But cases exist when you would create projects without activity duration or target deadlines:
When the process you manage has no defined lead times and activity deadlines
In such situations, you manage project steps with activity reminders.
When there is no apparent connection between project activities
Usually, such projects are used more as time management tools are generic or private projects.
