The document discusses perspectives on implementation that could be useful for service design. It identifies four key perspectives: (1) implementation as part of the development process, where design drift from concept to operational service needs to be considered; (2) implementation as a strategy, where stakeholder involvement is important; (3) implementation as design after design, where the well-designed service needs safeguarding; and (4) implementation as a change of practices, where organizational development must be anticipated and accommodated. Additionally, generic service resources and process models need to be adapted for implementation. The perspectives provide inspiration for service implementation but cannot be directly applied and more research on implementation in service design is still needed.
