ATLAS creating a titanic number of issues for housing benefit claimants and providers

ATLAS is an IT system used within the public sector to process Housing Benefit payments.  The trouble is it seems to not work in the way it should.  Each change in the claimants details whether it be a simple update of a telephone number will result in payments being suspended.

How can this be effective and efficient?  Any other IT system when updated would simply update and process the data appropriately.  Whats the point of a system that quite clearly does not work?

ATLAS is simply not holding up to scrutiny and is not doing the job it should. The system should either be upgraded or replaced.

What a waste of time, energy and money for everyone.
