Located at the top of the page, key dates allows you to see what tasks are nested within a phase and to track the status and progress of each phase from a high-level view. Key dates also allows you to add important dates for your company such as phase star and end dates, important events such as contract signing or project completion, or even company-specific events and holidays.
It is also possible to attach resources to each key date so that they receive an email notification that a key date has been assigned to them. And, you can even include the entire company if you'd like. This feature gives you clear visibility of the tasks and allows you to manage those tasks as well, updating the status or resources attached to it, changing the phase, or removing them entirely.
