You can customize the required properties for each type of card and for each board. The manager no longer has to waste time completing important information on the card. It is enough to configure the required properties once in the cards of each type or specific board, and the performers will immediately indicate all the necessary data on the task.
This is how the card looks like with the required property "Due date"
