Structure of KPI [8]:
The Telecommunication Technology Committee (TTC) in Japan has formed a sub working group for
SSC meetings to discuss the index system of SSC.

With the proposed KPIs of SSC [8], indicators are divided into four layers for simplicity, and
positioned "environment, economy, society, satisfaction" as the first layer. Since the notion of
"society" is broad, it is further split into "safety", "health", and "comfort," then positioned in the
second layer. The third layer includes indicators such as "information security" and "ubiquitous"
from the ICT perspective. The fourth layer includes data to calculate the KPIs in the third layer. The
main feature of the KPIs is that various units are used for data in the fourth layer as indicated in
Table H.1, while all other layers use a monetary value as the unit.
