No agreed KPIs: KPIs have not been set because this is a one-off, fixed-price R&D requirement with clearly defined deliverables and milestone payments linked to completion and NTS acceptance. Performance will be managed against the agreed programme, specification, quality requirements and contractual remedies. Separate KPIs would duplicate these controls and would not be proportionate to the nature of the contract.
