150 ITU‐T's Technical Reports and Specifications Identifying the existing governance and organizational conditions that would allow an efficient and effective management of SSC solutions; Identifying mechanisms for multi‐stakeholder involvement, citizen engagement, communication and information sharing throughout the SSC process. Assurance of the participation of citizens and relevant stakeholders in SSC is essential for the transformation process into a smart sustainable city; and Encourage the two ways of participation; top‐down or a bottom‐up approach. A top‐down approach promotes a high degree of coordination, whereas a bottom‐up approach allows more opportunity for common people to participate directly. In this phase, it is crucial to understand the city as an ecosystem. This ecosystem should be created by entities which are involved in the process of development of SSC strategies, including universities, research centers, companies, public agencies and society In this phase, local governments should achieve the necessary political approval and legitimization to ensure that the SSC strategic program is pursued. It consists of the adoption of the SSC program/targets by the local council through a political decision, thus becoming an agreed document that has widespread support. This would also serve as a reference for the strategic planning of the local authority. Any SSC initiative should have a strong political leadership from the local government. Additionally, it will be necessary to identify within institutions, organisms and/or businesses involved, the people with greater level of leadership. Such leadership should be conveyed through the initiative of project administration, the constant co‐ordination between the relevant actors, the decision‐making, the overcoming of challenges and any other action to guarantee the continuous development of the project. 3.3 Phase 3: Action Plan An action plan involves turning a suggested project into something tangible. This in turn requires a clearly defined plan for integrating technology solutions into an action plan. Important considerations can include: timing of the action; the costs related for implementation; the identification of who are individuals or agencies responsible for implementation; progress indicators; procedures for reporting and evaluation. In this phase, local governments work in close collaboration with the various SSC stakeholders to design the overall plan for the SSC's implementation (e.g., objectives, priorities, initiatives and actions needed in the short, medium and long term, including SSC infrastructure investments, setting measurable SSC targets and time frames for their achievement). This step involves, the identification of SSC targets and major milestones with regards to: SSC services; SSC Key Performance Indicators (KPIs); SSC architecture; SSC infrastructure and integrated platform; SSC data security, EMF ; and SSC projected cost benefit analysis. A plan of action must be elaborated which proposes a series of realistic development measures. Such measures will be hierarchized and studies will be done with regards to associated costs and
