Qualification Requirements to Test Traceability Matrix (RTTM)

Code Bodies have provided Requirement to Test Traceability Matrix (RTTM) templates for each non-Systems Integration Testing (SIT) Party type to support the assessment of testing activity. They clarify minimum requirements for test execution in Pre-Integration Testing (PIT) and will set out what is expected for Qualification Testing (QT) as well as any evidence that must be provided e.g. to support the Qualification Assessment Document (QAD) submission. Parties are required to complete the template to show that all tests have been executed and to provide evidence of this.   

The purpose of the RTTM is to provide traceability back to requirements across the different stages of Qualification (PIT, QT and QAD) and ensure that there is appropriate test coverage. It covers Functional, Migration, non-Functional and Operational requirements and will also support agreement of Placing Reliance arrangements. The RTTM will be assured by the Code Bodies for Suppliers and Agents and MHHS Programme for Non-SIT Licensed Distribution System Operators (LDSOs).

The templates are working documents for Programme participants so we expect that participants will update and submit this document multiple times to support their progress through MHHS Qualification. For non-SIT Programme participants, we expect that they will submit this document to support PIT entry, PIT exit, QT entry and QT exit. 

The main difference between the PIT and QT sections is that participants will need to map their PIT test scenarios to requirements whilst the mapping of QT test scenarios to requirements will be completed by Code Bodies.

You can find the RTTM templates in the library below. You can view the PIT deliverables timeline of when they are due to be shared with the Programme and Code Bodies below:

Non-SIT Qualification PIT Deliverables Timelines

The timeline shows all of the deliverables by participant (LDSO/Non-SIT Supplier/Non-SIT Agent) and we strongly encourage participants to review this document alongside reviewing the RTTM templates to understand when the deliverables are due.

The Programme published an updated version of the LDSO RTTM with the Qualification Advisory Group (QAG) papers in July 2024. You can view this updated version in the library below.

Supplier and Agent RTTMs

In November 2024, the Code Bodies issued updated RTTM Templates for Suppliers, Unmetered Supplies Data Service (UMSDS),  Smart Data Services and Advanced Metering Services. 
 
The updates are minor and include:

• Corrections to one of the Non-Functional Requirements across all four artefacts
• Adding additional Migration requirements into the Supplier RTTM
• Populating the entry criteria for the Qualification Testing column for Non-Functional and Migration requirements within the SDS RTTM, as well as updating one of the Functional requirements
• Minor update to ensure alignment with the Balancing & Settlement Code (BSC) and the Retail Energy Code (REC) Assessment Criteria

If you have any questions about these templates, please email the Code Bodies at MHHSQualification@elexon.co.uk and qualification@recmanager.co.uk
