Product design and service design Behavior Function Physical Structure Activity Environment Product Design Service Design Goal, Quality Specification Design objects (realization) Designers need to explain why and how design objects satisfy specifications.
Task of PSS designers <ul><li>Connecting individual products and services to be meaningful in a system (e.g., healthcare at hospitals). </li></ul><ul><li>Creating knowledge that relates individual products and services in a system. </li></ul>
Service CAD systematic PSS design <ul><li>Support PSS modeling . </li></ul><ul><li>Support PSS evaluation. </li></ul><ul><li>Support designer’s reasoning in design process. </li></ul>
Classifying PSS design information Medical care work flow at a hospital Activities Direct service Indirect service Enabling service Enhancing service Evaluation of quality Specifications Binary measurable specifications (service goal) Qualitatively or quantitatively measureable specifications (quality) Service environment Elements (provider, receiver, channel, content) Attributes and Relations among elements Design objects Other activities
