The model includes inputs and outputs of each activity, as well as factors that constrain and enable the activities (controls and mechanisms), using the IDEF0 methodology. It provides a baseline scenario that is relevant for stakeholders across  product development and supply chain, including business strategists, material suppliers, designers, manufacturers, consumers, and recovers/recyclers.
