The Benefits Processing Replacement Programme (BPRP), announced three years ago, was meant to save £60m annually by joining up the benefits payment more effectively.
Observers claimed in January earlier this year, that the introduction of the new Employment Support Allowance (ESA) changed the original remit of the BPRP, rendering the integration project obsolete.
But the BPRP system will be recycled for ESA processes, the same area involved in the DWP's debt management unit, responsible for recovering money owed to the government from benefit fraud or overpayments.
This department featured in reports last month claiming a backlog of more than half a million cases was caused by software problems.
And the DWP also announced in July that another ill-fated venture, the Child Support Agency would be wound up after its £450m computer system failed to deal with the number of claims.
