HMPPS told us it had learnt lessons from its transformation programme and was applying these to its re-procurement of its contracts to deliver tagging services. In addition to pursuing off-the-shelf systems, it told us that it had decided to limit the number of suppliers in its new model to two. As part of the new model, one supplier will provide field and monitoring services while the other will provide tags and other hardware.44 The Ministry told us that it considered whether it should contract with a single supplier, but believed this would concentrate the market too much. It recognised that, by definition, having two suppliers introduces some element of complexity.45 HMPPS hopes to mitigate future integration risks by: • ensuring potential suppliers demonstrate they have proven technology in place; and • taking a phased approach to confirming future system requirements. It believed suppliers will be able to integrate their systems in six months, but this remains untested at this early stage of the procurement.46
