Why no open competition
Single Suppliers Technical Reasons; Additional Repeat Extension Partial Replacement
Published justification

This contract is for the continued provision of services by the incumbent supplier.

The existing platform is deeply integrated with SNG's core systems and supporting business processes. These integrations have been developed and refined over time and are critical to the effective delivery of the service.

For technical and interoperability reasons, a change of supplier at this time would create significant challenges in maintaining compatibility with SNG's existing systems, interfaces, data structures and operational processes. Transitioning to an alternative solution would require substantial redevelopment, testing and migration activity, resulting in significant implementation risk, additional cost and potential disruption to business operations.

A change of supplier during the proposed contract term would therefore create a material risk to service continuity and the effective operation of the integrated solution. Continued use of the incumbent supplier is considered necessary to ensure ongoing interoperability, maintain service stability and protect SNG's existing investment in the platform and its integrations.

The direct award will also provide SNG with sufficient time to review its benefits strategy and undertake a comprehensive assessment of the market. During this period, SNG will evaluate available solutions and market developments and determine whether a future competitive procurement exercise would offer improved value and outcomes. SNG anticipates completing this review and determining its future sourcing strategy within the next two to three years.
