The Northern Ireland Prison Service (NIPS) is an agency within the Department of Justice. It is responsible for the operation and delivery of services within the Northern Ireland prison system. NIPS manages the offender life of approximately 1 900 inmates across three holding establishments, HMP Maghaberry, HMP Hydebank Wood and HMP Magilligan. Inmate information is critical as it is used to manage the inmate throughout his / her time in custody e.g. sentence calculation, security, safer custody, visits etc. It is also increasingly used to monitor the performance of the NIPS. Over the years, PRISM (Prison Record and Information System) has been the main repository for this information and, due to it fast becoming a business critical system, is now more important than ever. The scope of this procurement is for a Contractor to undertake the support and maintenance of the PRISM system.
