Sustainability Management Process. The management process includes a preliminary
phase, a planning phase, a monitoring phase, and a supplier sustainability
control. In the preliminary phase, the principles and criteria for sustainability are
established. In the planning phase, sustainability activities of the development
process are indicated, and the corresponding requirements as well as necessary
resources are planned. Afterwards, the sustainability of the deployed activities and
their conformity with the requirements are monitored. The last part of the management
process (supplier sustainability control) deals with sustainability policies
and requirements for supplied products and services. Here, an agreement needs to
be found and the supplier’s sustainability needs to be monitored.
