How does user involvement differ between traditional projects and agile projects? In a traditional project, the user is involved mainly during requirements definition; in an agile project, the customer is involved throughout the project. In a traditional project, the customer develops the high-level requirement; in an agile project, the project team develops the requirement document. In an agile project, the user has little contact with the developer; in a traditional project, the customer is part of the team. In a traditional project, the customer is part of the development team; in an agile project, the customer is not part of the development team
