Trello
Trello is a combination of a to-do list, visual tracking, and project management tool that lets you assign tasks to your team, include checklists, conversations, and documents, and track their progress.
Trello can be extremely beneficial for creating a task outline for company planning purposes, as well as assigning and tracking projects to completion. Its drag-and-drop Kanban-style task management interface makes it easy for everyone on the team to see how tasks are progressing across the pipeline. It has enough features to help you save time and get more done without having to worry about admin responsibilities, such as due-date commands, moving cards from one column to the next, and notifying team members.
