Trello uses boards, lists, and cards to make a workflow visible. A small team can start with a simple sequence such as planned, in progress, and complete, then add context to each card.
A simple board works best when the team agrees on what each stage means. For larger teams, check the Free plan’s workspace and collaboration limits, automation allowances, and whether the views you need require an upgrade.
