Trello is a Kanban-based project management tool used by the author to create dedicated project pages called boards, set up various lists (stages of a process), and organize cards (individual tasks) within those lists. To break down and track specific steps that need to be tackled within a task, the author uses Trello's checklist feature, which allows adding deadlines and different team members to each checklist item. This helps to create a systemized approach to content production, making it clear where content is in the production process and what needs to be done next. The use of checklists also adds granularity to tasks, helping to make progress visible beyond standard list stages.
