Quality Systems & Software Ltd

Institute Name: Quality Systems & Software Ltd

Description: Quality Systems and Software Ltd produces the software tool DOORS (Dynamic Object Oriented Requirements Systems). DOORS is currently the worlds best selling requirements tool, with 80% of the sales exported, mainly to the USA. Customers include blue chip names such AT&T, Ford, CNES, CERN, Sagem, ESA, DRA, Motorola, and Pitney-Bowes. DOORS is based on experience gained within the European Space Agency by Dr. Richard Stevens. QSS Ltd is therefore a rare example of a European software company start-up which has succeeded in the USA, and in the world market in general. Development of DOORS is done in Scotland, using requirements as the basis of management. Total QSS staff number 20. QSS Ltd is also involved in training in Structured Requirements and writing process standards for large organisations. More than 50% of this training is performed in the USA, normally within large corporations such as AT&T and Motorola..
