Planning for Complexity in Signalling Project Delivery

As rail networks transition from legacy signalling to advanced modern train control systems such as European Train Control System (ETCS) and Communication Based Train Control (CBTC), the complexity of the project can increase significantly. New train control technology can cause a multitude of integration challenges involving system interoperability, operational readiness, stakeholder alignment, and safety assurance processes. Unlike conventional re-signalling schemes, these programs require a systems engineering approach, robust governance frameworks, and adaptive delivery methodologies. To reflect the challenges being faced by our clients based on our experience, Network Rail Consulting (NRC) has developed the following tools and processes to significantly increase the chances of a successful project delivery.

Creating an Integrated Schedule

The delivery of modern signalling involves the development of complex subsystems typically commissioned by a range of vendors and partners through independent contracts and work packages. To manage the complexities, an integrated schedule is essential to help identify the large number of interdependencies and monitor the impacts of the program milestones as changes effect the subsystem deliveries. The integrated schedule is a complex and powerful tool that enables the program leadership to maintain control, however it is best used and understood by experienced planners.

Integration and Configuration Mapping

An integration roadmap is a ‘plan on a page’ that outlines the subsystem or delivery streams, interdependencies and influence on key integration milestones or nodes. By presenting complex integration in a clear and concise manner, the roadmap enables a shared understanding of the program priorities within the team, external stakeholders and supply chain. This supports the coordination and alignment of the program to drive all parties towards desirable program outcomes.

Establishing Key Program Milestones

Key program milestones are a carefully assembled selection of milestones that align critical integration nodes on the overall delivery plan. These sit at the top level of the integrated schedule and can be used to monitor and control the activities that lead up to these milestones. Whilst the key program milestones provide a framework for reporting to the client organisation, they can also be linked to incentives within vendor contracts and help shape behaviours from the supply chain that are aligned with program interests.

Visualisation

Within a complex signalling program, the visualisation of planning tools is transformational to project delivery. When complex information is conveyed in a digestible format it creates clearer decision making, effective problem solving and greater collaboration on the program.

In addition, critical elements of the development and delivery program can be tracked through time and emerging issues escalated quickly should risks to program delivery emerge that require rapid deployment of mitigations.
