The new Asana task templates feature gives users an easy way to quickly create tasks that contain checklists of subtasks and other key information. You could use task templates for things like meetings, new leads, client projects or content types.
I've been using task templates for the different types of content that I produce e.g. blog posts, podcasts and videos. Each template contains a different set of subtasks to be completed. This makes it a lot quicker to set up a task and means you won't forget important steps.
