Fastlåsing

Fastlåsing, or lock-in, refers to a situation in which a user or organization becomes constrained to a particular product, service, or standard because the costs or frictions of switching are high. The term is used across economics, information technology, and engineering to describe how dependencies on a chosen option can reduce flexibility and competitive pressure.

Fastlåsing arises from several mechanisms. Switching costs can be financial, such as fees or the need to replace compatible hardware; learning costs, where users must retrain staff; or operational costs, like reconfiguring business processes. Network effects occur when value increases as more users adopt the same platform, making leaving costly because alternatives offer less compatibility or fewer users. Data lock-in and interoperability barriers can make transferring information difficult, while contractual obligations or ecosystem control by a vendor further entrench the incumbent.

Domains where fastlåsing is observed include software and hardware ecosystems, cloud services, payment systems, and digital media platforms. For example, proprietary formats, exclusive services, and integrated hardware accessories can limit the appeal of switching to competing options. Lock-in also appears in areas like public procurement and regulated industries where standards converge around a dominant solution.

Policy and practice address fastlåsing by promoting open standards, interoperability, data portability, and multi-vendor ecosystems to enhance choice and competition. At the same time, some level of lock-in can provide stability, security, and investment signals, so policy responses often seek a balance between enabling competition and preserving beneficial incentives.
