Information and communication technologies (ICT) can provide added value in an organizational context in order to enhance the definition of business support strategies. The purpose of the chapter is to focus on the contribution of ICT to implement a sustainability policy in the organizations, in the context of the sustainable development goals to improve cooperation and promote development. In this context, the principles of the Karlskrona Manifesto are applied to the development of software systems. The methodology focused on the literature review of the domain and on a case study, in order to analyze the impact of ICT as an engine of sustainability in organizations. The main conclusions focus on the analysis of the impact of established practices in organizations to design and develop sustainable software systems. The results point to a greater consciousness of the potential effects of software systems on sustainability, which will improve management practices, reducing the quantity of material to be recycled, and aligning organizational strategies with Green IT.

Information and communication technologies can be an added value in order to provide integrated services to customers. With the technological advancements of the last decades, writing is increasingly done in electronic documents. Digital signatures are designed to ensure authentication, integrity, and non-repudiation of such documents. The methodology was based on the literature review of the field, as well as the description of the case study which emphasizes the added value of the developed application, since it addresses concerns of several dimensions of sustainability. The purpose of the chapter is to describe a case study in which an Android mobile application, SoftDigital, was developed for document flow management in a hospital environment, meeting the principles of sustainability design for the development of software systems. It is therefore considered that the main conclusions are to allow healthcare professionals and patients (or their legal representative) to integrate their digital signature into documents for approval of treatments electronically.
