As the backbone of the UK’s economy, the nation’s critical infrastructure – encompassing railways, highways, and industrial sectors – is designed to endure for decades, if not centuries. However, the software systems and digital technologies managing these assets have lifespans averaging less than ten years, creating a stark and costly disparity.

Zircon Software, a leader in bespoke software solutions for critical industries, has conducted an investigation into the growing challenge of software obsolescence. The findings reveal the operational, security, and financial risks posed by ageing software in long-lasting physical infrastructure.

The Growing Challenge of Software Obsolescence

Research highlights that while physical assets such as bridges and tunnels are designed to last 50 to 100 years or more, digital systems become obsolete in as little as six to eight years. For example:

• The adoption of predictive traffic management systems (PTMS) in the Highways sector, raises urgent questions about the compatibility of current infrastructure with future digital needs.
• In the UK rail sector, over 25% of Signalling Equivalent Units (SEUs) will have less than five years of remaining life by 2038, with this figure rising to over 35% in certain regions.
• Industrial sectors reliant on legacy machinery face compatibility issues with modern Industrial Internet of Things (IIoT) platforms, impeding operational efficiency.

Proposed Solutions for a Resilient Future

To address this critical issue, a strategic approach to obsolescence management is advised, including:

• Proactive Lifecycle Planning: Aligning software updates with the operational lifespans of physical assets to reduce failure risks.
• Modular and Cloud-Based Solutions: Developing software architectures that allow seamless updates and leveraging scalable cloud technologies.
• Digital Twin Technology: Using virtual replicas of physical assets to simulate and test updates, reducing costs and operational downtime.
• Investment in Innovation: Driving research and development to future-proof infrastructure and ensure compatibility with evolving technologies.

Building Resilient Infrastructure in a Digital Age

“Software obsolescence represents a growing threat to the resilience of the UK’s critical infrastructure,” says Dan Russell, of Zircon Software. “By adopting forward-thinking strategies and investing in modern technologies, we can bridge the gap between the longevity of physical assets and the rapid pace of digital innovation.”

Zircon Software calls on industry stakeholders and policymakers to prioritise obsolescence management as part of the UK’s long-term infrastructure strategy. Together, we can ensure that critical systems remain secure, efficient, and future-proofed for the demands of the digital age.
