Figure 1 shows the overview of service design
methodology proposed in SE. It is noteworthy that a
term service means a combination of service activities
and physical products as mentioned above. A service is
modeled as a functional structure that satisfies customer
needs, and specific entities and their activities/behaviors
are associated with the functional structure [3]. Here,
entities include both physical products and human
resources, which correspond to product share and service
share in PSS context.
