ITU‐T's Technical Reports And Specifications 197 city's complexities and dynamics may put into question, and even render useless large investments made on smart initiatives.53 In this sense it is important that urban planners participate actively in the design and implementation on smart sustainable city projects to foster a broader understanding of three basic characteristics of contemporary cities: complexity, diversity and uncertainty. A closer look at those three aspects may provide a clearer and more in‐depth understanding of the cities' nature and identity, particularly to stakeholders that lack an urban background. 4.12 Standards Developing Organizations (SDOs) SDOs are essential to the deployment of SSC as they can provide a standardized framework and a minimum set of characteristics to define and implement SSC. One of their priorities should be to develop a common terminology for all stakeholders to bring clarity and harmonization in this field.54 In addition, the success of SSC implementation will depend on the definition of measurement methods to assess the performance, smartness and sustainability of city services based on ICT technologies. There is a need to develop specific standards that can allow the various technologies involved in SSC to be able to interoperate.55 ITU with its Focus Group on Smart sustainable Cities has developed a Technical Report which identify the standardization gaps for SSC. Having identified the multiple stakeholders and the diverse roles that they play in SSCs, the following section provides a series of specific recommendations in order to ensure that these multiple views and contributions are effectively integrated as part of smart sustainable city strategies. 5 Conclusions As described throughout this report, the identification of SSC stakeholders is a critical component in the design and implementation of SSC strategies and projects. Cooperation between stakeholders is key for cities that want to become smart and sustainable. A thorough study of the characteristics and roles of the stakeholders can be useful to identify the relationships that exist among them, create useful synergies, and allow the integration of stakeholders' views on SSC projects and initiatives. In order to successfully develop an analysis of SSC stakeholders in a given city, the following three steps should be considered: Step 1: Identification of all stakeholders involved. It is very important to develop an initial list of stakeholders for a SSC project development. This list is not a closed list and can be updated. Step 2: Categorization of the stakeholders. It is important to categorize stakeholders based on their interests and to identify all the relationships among them. It is advisable to develop a stakeholder diagram and a map of their relations and interactions so as to facilitate further analysis. ____________________ 53 Universidad Politécnica de Madrid, contribution to FGSSC. 54 ISO Focus Magazine.
