Social Security's Office of Inspector General (OIG) has completed a "Congressional Response Report" on Progress in Developing the Disability Case Processing System as of March 2017. Here are some excerpts from the report (footnote omitted):
SSA partners with State disability determination services (DDS) to evaluate disability claims and make disability determinations. The DDSs use various customized systems to process disability cases.
DCPS is an SSA initiative to develop a common system for all DDSs that the Agency expects will simplify system support and maintenance, improve the speed and quality of the disability process, and reduce the overall growth rate of infrastructure costs.
SSA is using an Agile approach to developing DCPS. The Agency continually identifies functional requirements that are expressed as user stories. Each user story is assigned a level of effort, called a story point. Velocity refers to the number of story points completed during an iteration,or “sprint.” User stories that need to be addressed are considered the backlog. ...
In May 2016, SSA estimated the first release of DCPS would be available in December 2016 — at a cost of less than $38 million — and would support initial disability claims and reconsiderations. However, the Agency subsequently scaled down the functionality it would include in the first release....
At the time of our review, SSA was planning to deliver the functionality needed to process all initial disability claims and reconsiderations (as well as initial continuing disability reviews) by January 2018 at an estimated cumulative cost of $75 million. ...
SSA reported, that, as of March 14, 2017, it had completed 12,810 of the 22,082 total story points identified to-date (58 percent). ...
In August 2016, the vendor that supported the software used by 46 of the 52 DDSs announced plans to modernize its legacy systems over a 24-month period. Our December 2016 report stated that SSA should evaluate its plans to ensure it can demonstrate to Congress and the public that it has chosen the most cost-effective alternative to achieve its goals. At the time of this review, SSA was evaluating the cost and schedule of the internally developed DCPS compared to the vendor-developed alternative....
