These are some of the things I appreciate with the Clever Checklist application: it has an intuitive user interface, visual tracking of percent completion so it's kind of easy to see the status of the task list and there is the ability to set deadlines and get notification when a to-do list is due. It also allows you to save templates so you can reuse a checklist for other projects similar to a previous one, which helps save time for QA testers. It is also very simple and easy to use so there is no training involved - employees just create an account, access it and are able to use it right away.
