This paper describes a part of the Intelligent Lifestyle project conducted at the University of Melbourne in cooperation with our industrial partner Adacel Technologies in 2004. The Intelligent Lifecycle project aimed to design and build a system of intelligent agent-based appliances. It further aimed to demonstrate that agent development methods were suitable for wide acceptance by software developers with object-oriented but no agent-oriented experience. In this paper we describe how initial requirements engineering activities undertaken using the ROADMAP methodology can be complemented by rapid prototyping performed by using the RAP/AOR methodology. Overall, this paper defines and explains the first two stages of a systematic approach for achieving systems of intelligent agents.
