198 ITU‐T's Technical Reports And Specifications Step 3: Detailed analysis of selected stakeholders and engagement. This is the most important step of the process. In order to succeed, a detailed analysis of all stakeholders must be done. This is a reiterative process that can be repeated as new stakeholders emerge and new projects and initiatives are carried out in a SSC project or initiative. It is important to have a final summary table reflecting the stakeholders' aims, challenges, potentials and constraints, and especially their role and contribution to the SSC challenge (as reflected in Annex 1). This will set the basis for proper stakeholder’s engagement. For a smart sustainable city initiative to succeed, it is important to identify all the stakeholders involved in order to guarantee its success and sustainability. Cities are complex systems with several stakeholders. In a smart sustainable city, stakeholders interact together to build a resilient city which is smart, sustainable and innovative. In addition, it must also be taken into account that cities from developed and developing countries differ in terms of their existing infrastructure as well as the multi‐stakeholders' ability to implement ICTs within the city. In other words, what may be feasible for one city may be challenging for another. It is imperative that a multi‐stakeholder approach is applied to achieve the highest rate of success by working together as a team irrespective of the city they are based in.
