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, which reduces the need to rely so heavily on cross-pollinating skill on the crew. Though crews are meant to be interchangeable on crews within a hover, they always stay within the hover long-term.
