Tasks are at the heart of tracking your production with Producer. They can can be automatically created when new scenes are added or they can be created manually. Tasks are the practical form of the processes that make up workflows—see About Workflows.
Tasks are usually created automatically because workflows have a default setting to automatically create tasks. When you create an item, such as a scene or an asset, and you select a workflow using the auto-create setting, all the processes of this workflow will be converted into actual tasks for this item. However, if you selected a workflow where the auto-create tasks has been disabled, the item may appear like the example below and you will have manually create a task.
Accessible from the main menu, My Tasks is a very useful place listing all the tasks that are currently assigned to you.
