Designing effective gamified solutions is a difficult and highly complex task. Supporting tools for requirements analyst are very rare, while most existing tools provide automation for reasoning over complex knowledge models. Drawing from our involvement in EU Projects and extensive analyst feedback, this paper presents crucial lessons learned on automating gamification analysis and design. We employed these lessons to guide the development of Web-Agon, a web-based solution that automates reasoning over models to support the analyst. Web-Agon, based on the Acceptance/Gamification Requirements Agon Framework, facilitates systematic gamification analysis of software systems. This approach, driven by acceptance (psychological, sociologi-cal, behavioral) requirements, has proven effective in designing systems that positively engage users. Based on models and gamification principles, Web-Agon contributes to building user-centered, engaging software systems. We have evaluated the effectiveness of our tool through a case study on Participatory Architectural Change Management in Air Traffic Management (ATM) systems with the use of Web-Agon for system gamification. We obtained positive results in terms of supporting analyst in a structured, systematic and automated way, reducing potential errors, thanks to automated functionalities, as well as speeding up the gamification process.

Privacy and security requirements, and their potential conflicts, are increasingly having more and more importance. It is becoming a necessary part to be considered, starting from the very early stages of requirements engineering, and in the entire software engineering cycle, for the design of any software system. In the last few years, this has been even more emphasized and required by the law. A relevant example is the case of the General Data Protection Regulation (GDPR), which requires organizations, and their software engineers, to enforce and guarantee privacy-by-design to make their platforms compliant with the regulation. In this context, complex activities related to privacy and security requirements elicitation, analysis, mapping and identification of potential conflicts, and the individuation of their resolution, become crucial. In the literature, there is not available a comprehensive requirement engineering oriented tool for supporting the requirements analyst. In this paper, we propose ConfIs, a tool for supporting the analyst in performing a process covering these phases in a systematic and interactive way. We present ConfIs and its process with a realistic example from DEFeND, an EU project aiming at supporting organizations in achieving GDPR compliance. In this context, we evaluated ConfIs by involving privacy/security requirements experts, which recognized our tool and method as supportive, concerning these complex activities.
