From the Manage Task Types dialog box, you can edit Task Types. For example, you can add or delete attributes, edit parameters, add or delete questions, edit instructions, or change the order of questions.
Editing Task Types may have an effect on tasks that have already been created from the Task Type. For tasks in a template, the effect is immediate. Any change that you make to the Task Type (instructions, questions, and so on), is automatically updated in any task of that type. If you edit a Task Type in a schedule, it does not have any effect.
