About the DII Programme

DII Mission:

To deliver to Defence a secure and coherent information infrastructure at minimum whole life cost whilst maintaining continuity of service.

DII is essential to the future capability of the MoD and the Armed Forces. The scale and the inherent complexity of DII presents significant challenges to ATLAS and the MoD, all of which need to be overcome. DII is far more than the provision of terminals - it is a fully managed and supported infrastructure service, giving user support twenty four hours a day, seven days a week, worldwide. In addition to the terminals themselves, the Programme must also deliver the supporting infrastructure including data centres, individual site designs, user support and directory services, as well as migrating existing MoD applications to operate on the new infrastructure.

  • Over 300,000 Users
  • 150,000 Terminals
  • 2,000 MoD Locations
  • 500+ Applications
  • Unclassified to Above Secret
  • Fixed sites (UK and abroad) and Deployed HQs

A single Information Infrastructure

The MoD requires secure, high-quality information technology both for the success of operations and to conduct its day-to-day business. As in many other organisations, the MOD has developed numerous IT systems to meet a wide range of needs over many years. In 2000, the Department began to develop plans to replace these diverse systems with a single Information Infrastructure to enable better communication, to promote more efficient ways of working, and to obtain better value for money.

Business Benefits

From the outset, the DII group and ATLAS have worked to maintain a focus on the realisation of business and operational benefits, as well as achieving other benefits, such as better ways of working, more collaboration and easier communication. This focus has, and will continue to be, a major influence on Programme scheduling, with adjustments being made to optimise the benefits to the MoD. On current estimates, DII will enable the realisation of £1.5billion of efficiency savings across the Defence Change Portfolio, over the 10 year DII contract.

Defence Operational Imperatives

In addition to supporting the structural changes of the MoD, the DII Programme must also support operational requirements, which cannot always be predicted and may require a rapid response from inception to live operation. These have influenced programme requirements, direction and scheduling.

  • J1/J4 IOS - Interim Operations Support - In October 2006 ATLAS received a request to provide services including access to Joint Personnel Administration (JPA) for forces deployed in Afghanistan. The project, known as J1/J4 Interim Operations Support (J1/J4 IOS) now provides a capability that can handle material classified as Restricted in operational theatres. The main aim of the system, which comprises 350 mobile terminals and accompanying servers, is to provide military personnel on deployments with access to JPA and other logistics tools, allowing them to monitor and manage their pay and annual leave. The new system was successfully delivered in a very short period of time, by May 2007.
  • OVERTASK - fills a capability gap for Communications and Information Systems (CIS) for deployed British forces in Afghanistan. The MoD contracted ATLAS to fulfil the requirement, essentially to replicate the existing NATO system by providing an extension to the network, with access to NATO systems and applications classified as Secret. The requirement comprised some 200 terminals and associated servers. Following very rapid work to ascertain the scope of the project, the new system was delivered in August 2007 and is now operating successfully in theatre. This success led to further opportunities for the OVERTASK team, with a further 230 terminals deployed in April 2008. Recent developments include a highly mobile and man portable version of the OVERTASK capability which will allow the rapid deployment of mission Secret CIS Capability.

Incremental Approach

Contracting, development and implementation of DII is based on an incremental approach designed to de-risk the Programme and enable the MOD flexibility in defining its future requirements. This approach is based on changing operational and business drivers, as well as affording the opportunity to ensure continued value for money.

Solution Components

In addition to the challenge of the technical requirements, is the challenge of immense scale: to establish DII as the single information infrastructure used by the MoD, establishing security domains from Unclassified to Above Secret; roll-out to over 2,000 fixed sites as well as to Deployed environments and maritime platforms. DII must deliver this with common services, Medium and High Grade Messaging and support access to legacy services and infrastructure, whilst the MoD also undertakes other change programmes and is deployed on operations.
