About the work

Why the work is being done
The MOJ has a bold strategic vision for the delivery of digital, data & technology in Her Majesty's Prison and Probation Service (HMPPS) which includes:
● Deliver digital prison services that replace legacy systems and support rehabilitation
● Build strong digital & technology capability

As part of this there is a clear need to build a consistent set of long-lived interfaces that expose data from HMPPS systems in a coherent and consistent way.
Problem to be solved
The MOJ has data about prisoners and probationers that comes from many different systems (in particular, NOMIS, nDelius, OASys, PPUD). Many of these systems hold data about the same individuals but using different structures. The MOJ is also planning on replacing at least one of these systems over the next few years. HMPPS Digital has a number of existing APIs and message queues that expose data, but many of these are tied to legacy systems and data models.

The MOJ needs to deliver a set of new interfaces that will provide data from HMPPS systems in a way that abstracts the above difficulties away from the consumers of the interfaces. We require a managed service team to continue defining the high-level data requirements, investigate the technical requirements and constraints, develop a consistent approach in line with our architectural standards and technical governance, and develop a service to meet both the long term needs of HMPPS Digital and the identified needs of data consumers. The new interfaces are likely to consist of two parts: a set of person-focussed APIs, and a set of queue-based domain events.
Who the users are and what they need to do
The actual users will be using the resulting services not directly but via other systems: where we have limited scope for change. For this requirement, we should instead consider the system to system integration
Early market engagement
Any work that’s already been done
Some initial high-level data requirements have been defined and discussions have taken place with an external organisation. We have some technical standards, but not a complete set
Existing team
There will likely be a need to work closely with existing development teams within HMPPS Digital, but this will be a new team managed by the supplier.
Current phase
Not started

Work setup

Address where the work will take place
Working remotely although occasional travel may be required to either:
- 102 Petty France, London SW1H 9AJ

Security clearance
SC clearance is required

Additional terms and conditions
