Building on the business model in the requirements study they developed an evolutionary prototype using a data driven approach to the order of prototypes (00421, 00369). Three or four main prototypes were developed with typically three or four versions of each major screen discussed at all day workshops (00256).The workshops were held every week or fortnight (00268) beginning first with a brainstorm of functionality (00979), progressing through paper models and moving on to PowerBuilder screens (00256). Workshops continued for five months. Technical discussions were held outside the workshops (00978). Equipment was installed in the City to allow the prototypes to be discussed in the workshops (00980). The workshops were attended by underwriters at various levels, someone from Services (usually Lucy - 00497), someone from Claims (00256) as well as Keith and David who chaired the workshops (00977). A server and PC were installed in Holland and the USA so that once the prototypes had been discussed in the UK they could be discussed in Holland and the USA (00259).
After the workshops the prototypes were installed on a PC so that they could be used (00258). Unfortunately both Services and the underwriters only really played with the system despite David's influence (00498, 00287).
