## Summary

The procurement process for "Cylc Tranche 3," led by the Met Office based in Exeter, UK, has reached the award stage. As a central government public authority, the Met Office facilitated this direct procurement below the threshold without competition. The contract, valued at £65,000, focuses on services related to the design and execution of research and development in collaboration with the National Institute of Water and Atmospheric Research (NIWA) from New Zealand. The contract commenced on 17th October 2025 and will conclude on 31st March 2026. This procurement addresses efficiency issues in the Cylc8 development, a vital workflow engine underpinning operational systems, ensuring continued progress in this critical area.

This tender presents growth opportunities for businesses specialising in research and development services. Companies with a strong background in developing and maintaining sophisticated software systems, particularly those that have experience in the environmental or meteorological sectors, would find this contract particularly aligned with their expertise. Businesses aiming to expand internationally, notably with connections or interests in New Zealand, would be well-suited to similar tenders. Engaging in collaborations with prominent entities like the Met Office can significantly enhance a company’s reputation and market presence in the public sector.

## Notice

ESNZ (formerly NIWA) leads the development of Cylc, the Workflow Engine that underpins research and operational systems across the Partnership - NIWA - Cylc Development.docx. Recently the Cylc developer core team lost a significant fraction of the resource needed to continue the development of these plans and deliverables - 1.6 FTE across ESNZ and the Met Office. Note ESNZ maintains a significant ongoing investment in Cylc development, funding someone at nearly full time on the project - which is our primary Momentum Partnership Leadership Activity. This loss of resource is expected to impact several high priority efficiency issues in Cylc8.
