CMMI Case Studies - BT Global Services

BT Global Services
As part of the BT Health programme BT Global Services was working with the NHS in London and the south of England to modernise its IT systems and services.

To support the maintenance and development of a systems infrastructure for the testing of new services to the NHS Trinity were engaged to define and document a single set of integrated processes. When complete and supplemented with supporting work instructions, also defined by Trinity, they combined to satisfy all practices of Maturity Levels 2 and 3 of the CMMI.

These new processes enabled the amalgamation of three separate BT departments into a single entity which was anticipated to save the programme £713,000 per annum and had the potential to achieve £5.7M over the life of the programme.

An additional benefit attained was an increased efficiency in excess of 280 man days per month resulting in further savings of over £600,000 per annum.
