The Department has a vast IT estate: its pensions, disability services, working age benefits, child maintenance and Universal Credit technology is used annually to pay £165bn for seven million claims and these services must run at 100% up time.
These IT systems are used 90,000 staff across 950 locations along with 22 million citizens and yet have not been updated for decades.
They have also been designed in isolation which led to integration issues on top of other problems caused by using such aging technology.
In the past 80 days, DWP teams have worked to achieve what they are claiming is an 82% productivity increase as a result of solving outstanding IT issues.
"The results speak for themselves, in the last 80 days service hours lost due to IT issues across our IT estate have plummeted by 82%. 40 top issues have been fixed," claimed Mayank Prakash, director general of the technology department at DWP.
Prakash has also said that his team have delivered automated interfaces between two key systems, automated production of reports, reduced processing times and reduced times to log onto virtual desktops.
