SMM: A Maturity Model of Smart Cities Based on Sustainability Indicators of the ISO 37122

Most indicators used for Smart Cities do not follow a pattern and/or are not able to be compared to each other In order to standardize the maturity evaluation of these cities, the present work aimed to propose a new framework to evaluate the maturity degree of a Smart City. The Sustainability Maturity Model (SMM) was inspired by CMMI maturity indices, by COBIT process controls and ISO 37122 indicators. Thus, the steps of the framework were developed, and a case study was carried out in a hypothetical city in order to validate it. As a result, it was observed that SMM allowed classifying the city by its maturity level based on the sustainability indicators of ISO 37122. This assessment can add value to a city aiming to become smart, and can serve as basis for applying new assessments and measuring the evolution of these environments.
