Abstract. The agent-oriented software engineering methodology Tropos offers a structured development process and supporting tools for developing complex, distributed systems. The objective of this paper is twofold: first, to illustrate the use of Tropos to develop a Multi-Agent System, performing basic analysis and design activities, code generation and testing, with the support of a set of tools; second, to enable the comparison with other, tool-supported, agent-oriented software engineering methodologies through a description of the main steps of these activities and of excerpts of the resulting artefacts, with reference to a common case study, namely, the Conference Management System case study.

Self-adaptive systems should autonomously adapt at run time to changes in their operational environment, guided by the goals assigned by their stakeholders.We present a tool that supports goal-oriented modelling and generation of code for goal-directed, selfadaptive systems, supporting Tropos4AS, an extension of the software engineering methodology Tropos.

Abstract. Managing risks related to OSS adoption is a must for organizations that need to smoothly integrate OSS-related practices in their development processes. Adequate tool support may pave the road to effective risk management and ensure the sustainability of such activity. In this paper, we present the RISCOSS platform for managing risks in OSS adoption. RISCOSS builds upon a highly configurable data model that allows customization to several types of scopes. It implements two different working modes: exploration, where the impact of decisions may be assessed before making them; and continuous assessment, where risk variables (and their possible consequences on business goals) are continuously monitored and reported to decision-makers. The blackboard-oriented architecture of the platform defines several interfaces for the identified techniques, allowing new techniques to be plugged in.
