346 ITU‐T's Technical Reports and Specifications 5.3 ICT Architecture development methodology According to the above findings, the definition of an architecture has a lot to do with information collection and understanding of all the stakeholders' needs, together with the limitations that come from the external environment and of the laws that impact the operation of system. As such, the following process is suggested to lead the architecture development (Figure 2): Figure 2 – ICT architecture development methodology 5.4 Smart Sustainable City ICT Architecture This document emphasizes on the technical architecture from the architectural perspectives, which defines the platform on which the SSC organization (i.e., government, project coalition or business) builds and uses ICT in order to achieve in its defined mission [14]. To this end, the SSC architecture is the element, which: describes and defines the structure of the environment in which business systems are delivered; creates and maintains a set of core technology standards with which the SSC organization can measure technology projects; is an organizational capability – the people within (and outside) the ICT organization who provide strategic technical advice; is a means of resolving organizational technical issues; sets system (and hence software architecture), project, and corporate technology direction; establishes a reasoned approach for the integration of technology and business systems; establishes a framework for technology procurement decisions; both provides input to and is driven from the ICT planning process; allows the organization to control technology costs; develops a clear understanding of an organization's critical technical issues; •High level decisions that influence system structure (selection and trade‐offs)Meta‐architecture •Structure •Relationships •Views •Assumptions •Rationale Architecture •Models •Guides •Templates Guidelines
