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.
Chapter Preview


It is considered that knowledge is creative and must be stimulated to develop itself (Davenport & Prusak, 1998). In this way, technology can constitute a means to optimize communication and collaboration between employees, enhancing the sharing of experiences and skills. Today's projects increasingly demand agile and human-centered approaches to discover and meet the often complex needs of the various stakeholders involved (Hehn & Uebernickel, 2018).

Key Terms in this Chapter

Information Systems: Is the organized set of components such as people, processes of collection and transmission of data and material resources, automated or manual. The interaction of components enhances the processing and dissemination of information.

Agile Software Development: Software development process that favors direct communication between all stakeholders and simplifies documentation.

Requirements Analysis: Iterative process to identify features and restrictions with a view to developing or changing a software product. Use Cases are commonly used here.

Software Systems Development: Set of activities involved in the production of software. These activities are related to each other in an iterative and incremental process.

Sustainability: Ability to sustain life on the planet, considering the five dimensions: individual, social, economic, technical, and environmental.

Karlskrona Manifesto: Establishes the principles and dimensions for the design of sustainable software systems.

Digital Signature: From the Citizen Card it is possible to make the electronic signature through the Digital Mobile Key, speeding up the process of signing documents.
