Case studies

TRUMP applied the recommended methods in two contrasting environments: the Inland Revenue in conjunction with EDS in the UK; and the LAHAV division of Israel Aircraft Industries (IAI) in Israel.

The usability maturity of each organisation was assessed to identify which user-centred methods were needed. The methods were applied in trial projects over a 12 month period. In both cases the results were judged to be highly beneficial and cost effective, and the selected methods are now being formally incorporated into the organizations' development processes.

Inland Revenue/EDS

Inland Revenue provides data processing to support 60,000 staff in more than 600 local offices, and for tax and tax credit projects uses a well-defined rapid application design (RAD) methodology in conjunction with one of its main IT suppliers EDS.
