When subtasks help

Large tasks feel heavy because you cannot see the first step. Breaking "Plan the offsite" into small steps makes it concrete: you can start, finish one part and see progress. Subtasks do this inside the parent, so everything stays together.

A worked example

Parent: Plan the team offsite. Subtasks: Pick dates, Shortlist venues, Send survey, Book venue, Share agenda. As you tick each one off, the parent's progress updates, which makes a big project easier to continue day after day.

Good subtask habits

• Make each subtask small enough to finish in one sitting.
• Start each with a verb: "Call", "Draft", "Send".
• Give a date only to subtasks that really have one. Not every step needs a deadline.
• Keep to one level of steps. Deeper nesting is hard to read on a phone.

Free alternative

Subtasks are a Premium feature. On Free, create separate tasks and link them to a parent. That gives a similar structure, with each child as a full task.

Common mistakes

• Creating twenty subtasks for a simple job. If a task has one step, it does not need subtasks.
• Hiding the real next action. Put the first step at the top so you know where to start.
