Box 1: Smart Sustainable City Maturity Model

The Smart Sustainable City Maturity Model (SSC-MM) defines five levels of maturity in the
process of becoming a smart and sustainable city with each level achieved being a higher level
of maturity. The requirement to reach the intended maturity level is to achieve the target KPI
values set for each maturity level.

As an example, for KPI Household Internet Access, a level 1 maturity level could be to collect
the initial benchmark data. The further four levels could then be set as performance levels
such as level 2 achieved at 30% access, level 3 at 50 per cent access, level 4 at 70 per cent
access and level 5 at 90 per cent access.

This can then be overlaid with maturity level performance for the other dimensions to provide
insight into the issues that need to be addressed within each city to become smarter and
more sustainable.

Bizerte and other cities are encouraged to use Recommendation ITU-T Y.4904 as a framework
to determine their interim target values for KPIs by taking into consideration their priorities,
constraints, resources and optimal KPI performance levels. The SSC-MM is another tool that
can be used to communicate progress to stakeholders, help to develop and then execute a
SSC strategy and encourage the effective use of ICTs.

More information on the SDGs, the U4SSC initiative and the U4SSC Smart Sustainable Cities Index can
be found in the Appendix.

At this time, ITU would like to invite cities around the world to implement the U4SSC KPIs for SSC. Using
the U4SSC KPI definitions and data-collection methodologies, all cities will be able to better establish
clear data-collection methodologies, collect data consistently in a structured way, develop goals and
targets for each KPI and collect data regularly to track their progress toward smart sustainable goals.
