Any healthy garden has a landscape crew whose job is to bring vibrancy and beauty to the garden in every season and provide continual maintenance and health. A hover crew is similar, in that they are a group of assembled and autonomous producers who tend to the work that produces continual vibrancy and delightful value to the consumer. They also provide continual maintenance to the code and product support.
Their skill sets are constantly rigged and aligned to the new work to be delivered within a circuit. Because of this, crews are meant to be interchangeable within a hover, but they always stay within the hover long-term.
