Engineering Management

Providing systems engineering leadership within a major rail infrastructure programme

Client: Network Rail plc

Context

Network Rail's £8Bn West Coast Route Modification programme was Europe's biggest and most complex railway project, involving the wholesale modernisation of the West Coast Main Line, linked to the introduction of a new generation of high speed tilting trains onto what is Europe's busiest mixed traffic railway. The work involved many different engineering disciplines in a programme of renewals and enhancements, and including significant technological change in signalling, control, communications and traction power supply systems.

What we did

integrate provided the programme's Systems Design and Integration Manager during a significant part of the programme.

A major contribution made by integrate was the design of the overall approach to managing requirements and associated verification & validation data, including the design of a DOORS database implementation and supporting tools. The approach was based upon the principles of 'rich traceability', using structured arguments and evidence to build a convincing case for acceptance.

The integrated DOORS repository provided an accessible and productive environment for gathering V&V data and monitoring progress through to eventual acceptance, and has been used to produce the core data supporting programme Acceptance Cases.

Other activities undertaken by integrate included:

  • leading top-level requirements engineering and system design activities, including production of key engineering specifications for the programme
  • managing the high-level system assurance programme, including verification & validation, system reviews and production of the system acceptance case
  • managing and developing the central systems engineering data management database
  • developing and documenting systems engineering processes for the programme as a whole

Outcome

Aside from the specific contribution to the West Coast Route Modification programme, the underlying concepts employed by integrate to address the challenges of requirements management, validation and verification of complex systems have been developed further in terms of the processes involved and the tool support needed.
