Definition

What is Subtask?

A subtask is a smaller piece of work nested under a parent task, used to break a larger item into concrete steps that can be assigned, dated, and checked off individually.

A subtask decomposes work to a manageable size. When a task is too big to act on directly, breaking it into subtasks turns a vague item into a clear checklist of steps, each of which can have its own owner and due date while rolling up to the parent.

This structure keeps large work honest. Progress on the parent reflects the subtasks completed beneath it, so status is grounded in real steps rather than a guess. It also lets several people contribute to one deliverable without stepping on each other, since each holds distinct subtasks.

In Atlas, subtasks sit within the same task and project structure as everything else, so the breakdown of a deliverable lives next to its owners, dates, and any dependencies, giving one connected picture from the smallest step up to the project.

FAQ

Questions, answered.

When should you use subtasks?
Use subtasks when a task is too large to act on directly. Breaking it into smaller steps, each with its own owner and due date, makes progress concrete and lets several people contribute to one deliverable.
How is a subtask different from a checklist item?
A checklist item is usually a simple tick within a task. A subtask is a fuller unit of work that can have its own owner, due date, and status, and it rolls up to the parent task.
