|July 17th||The (failed) NHS IT system - NPfIT In 2001 the Department of Health embarked on a major IT investment for the NHS in England. This was the NHS National Programme for Information Technology or NPfIT. The motivation was based upon the twin beliefs that (1) the NHS was an organisation that had not made the best use of Information Technology and that savings would be possible; and that (2) centrally held electronic patient records would be a smart way of improving patient safety and improve the efficiency of communications. 10 years on and the Health Minister (the ever popular Andrew Lansley), scrapped NPfIT in 2012. How did this happen? What lessons can be learned from this major programme failure?||Geoff Balls|

Keith joined the transmission division of the BBC as a Technical Operator in 1973. Following a five year spell in Operations and Maintenance he transferred to the projects division, where he has effectively remained ever since, progressing to his current role of Principal Technologist. Arqiva is the ultimate result of past privatisations of the transmission divisions of the BBC and IBA. Keith has worked in many fields, specialising particularly in digital technology. Having played a significant role in the development of the UK DAB transmitter network he went on to act as the Technical Manager for his company’s roll-out of the UK DTT network in 1998. He subsequently acted as the Technical Manager for the re-launch of the UK digital TV network as Freeview. Keith represents Arqiva on many industry bodies, in particular the UK DTG and DVB.
