The book draws on selected invited papers from the 26th International Conference on Information Systems Development (ISD) held in Larnaca, Cyprus, September 6 - 8, 2017. The revised and expanded papers present research that focuses on methods, tools and management in information systems development. These issues are significant as they provide the basis for organizations to identify new markets, support innovative technology deployment, and enable mobile applications to detect, sense, interpret and respond to the environment.
