Teams generally have several to approximately ten members and use Scrum development, with many teams working in two-week sprints. Scrum events and working methods are determined by each team. Product requests are initially handled by the product manager and brought to the team through Scrum events. The posting also describes participation in online customer meetings, user interviews at logistics sites, and study sessions with customer success members to deepen product and domain understanding.
