The paper will report upon the experiences and reflections of undergraduate students undertaking industrial development projects, as part of their curriculum, in the situation where they have been required to utilize a prototyping / agile / lightweight methodology. The paper is partly evangelistic (demonstrating the author’s enthusiasm for a particular development methodological viewpoint), and partly methodological (discussing the characteristics of, and success in using, a particular methodological approach). A clear position in support of agile development methods is taken, and a particular method, called the Focal Entity Prototyping Approach, published by the author, is a main item of interest in this discussion.
