Introduction

Non-functional requirements describe how the Solution works, not what the Solution should do, and serve as constraints or restrictions on the design of the Solution. The following non-functional questions are to enable The Authority to assess the risk associated with the Compliance Assessment of the Solution against the overarching Service Management, Information Governance, Security, Testing, and Business Continuity and Disaster Recovery Standards. Supplier’s answers will also demonstrate they understand the non-functional landscape of the market they are selling into.

 

Non-Functional Questions Model

The Non-Functional Questions (NFQs) model illustrated within Figure A attempts to show the relationships between the Supplier’s Solution and the non-functional requirements (NFRs) required to meet the Overarching Standards, provide appropriate levels of service and, where relevant, satisfy the required service SLAs.

Suppliers are responsible for ensuring the non-functional elements of their Solutions are capable of meeting any defined service levels for specific Capabilities provided, as well as any other NFRs specified by The Authority across other Standards. 

Suppliers must provide an appropriate answer to the Non-Functional Questions - the level of information and evidence required in the answer will depend on the Capabilities and scale of deployment of the Supplier’s Solution and this will be determined and specified in the guidance provided as part of the Capability Mapping and Standards Compliance Onboarding process.
