The Ministry of Defence has saved more than £10m by cutting the number of applications it runs by 150, with more cuts to follow.
Since 2000, the MoD has been developing a single integrated IT infrastructure across all the armed forces. Alongside this project, it has developed a Defence Information Exploitation programme to reduce the number of applications run by the three services, which historically have managed IT separately.
"We were running disparate infrastructure and applications," said Lieutenant Colonel Paul Crossman, head of the rationalisation programme. "When you look at our legacy applications there is a lot of duplication, redundancy and inefficiency."
The MoD will move more than 1,000 applications onto the new infrastructure, ranging from everyday office systems to specialist tide and ocean current modelling applications.
It was using over 30 different applications to run libraries across the world and the project has narrowed this down to seven, while also cutting down graphics software from 25 to five programs.
Consultancy Detica worked with the MoD to form subject matter groups, groups of interest of legacy application users and legacy application developers.
