While our solutions often serve our customers for decades, the opportunity to follow a clear, upgradable program enables customers to have a safe, cybersecure, maintainable system with the latest functionalities to better achieve their goals. And as systems age, there can also be risks that are related to the availability of underlying components or software. Typically, these risks start to become evident after about 10 years of operation, but risks related to software may appear in shorter cycles, driven by lifecycle support decisions made by suppliers of operating systems, for example.
Generally, ABB’s intention is to support our systems as long as possible, with best efforts made even for the oldest systems. But limits to this support can arise when components or software becomes unavailable in the market. Many efforts are made by our design and supply chain teams to reduce these risks, with design modifications for available components, and even with large last-time buys of scarce components. We are often able to extend the lifecycle of our systems well beyond the lifecycles of the underlying components or software.
Fortunately, ABB also offers many sensible upgrade steps for customer to take in order to refresh our systems and reduce or remove these risks and even restart the clock on the system’s lifecycle, rather than fully replacing the system. This also helps customers extend the lifecycle of their products to minimize waste and production-related emissions, for as long as is viable. We also offer buy-back programs for applicable solutions and there is work in progress to enable circularity of hardware.
But every system has its practical lifetime limit, and so we transparently categorize each solution's lifecycle status in one of four phases. These phases help customers decide when they can expand upon a solution or when an upgrade or replacement is needed.
