Pick a template from the gallery, or your organization's own saved templates, and Asana creates a new project with sections, custom fields, and placeholder tasks already in place, saving the setup work of building that structure from a blank project every time.
A single task can also be saved as a task template, useful for a recurring deliverable (a weekly report, a client onboarding checklist) that gets created fresh with the same subtasks and fields every time it's needed, without manually rebuilding the checklist.
Admins on paid tiers can designate required or suggested templates organization-wide, which keeps every team starting from the same structure rather than each person building their own version of the same workflow.
