Systems Integration Testing (SIT)
What is SIT?
Systems Integration Testing (SIT) will test the end-to-end (E2E) MHHS Design, ensuring that the new MHHS arrangements function correctly and have been implemented in accordance with the MHHS E2E description.
Participants will demonstrate functional, non-functional and migration-related characteristics of the Market Interfaces and Services in an integrated, end-to-end environment.
For most participants, SIT is a voluntary phase of the Programme. SIT will not start until all Core Capability Providers have completed their design, build and Pre-Integration Testing (PIT). The number and types of participants joining SIT must be sufficient to form the Minimal Viable Cohort (MVC). You can view the timeline for SIT in the PoaP in the Quick Links.
In February 2023, we held a webinar to support participants in their understanding of SIT. You can view the slides, recording and Q&A on the MHHS Open Days and Webinars page of this website.
The Component Integration Testing (CIT) phase of SIT started on 30 October 2023. SIT Volunteers will be progressively onboarded according to their system and role.

Paths to Migration
To verify participants’ fitness to take part in the new Half-Hourly arrangements, participants must test their systems for compliance with the E2E MHHS Design.
There are two paths to migration, either via Qualification Testing, or the earlier route of SIT.
If participants take part in SIT, they are not currently expected to undergo additional Qualification Testing in the Qualification phase.
SIT Pre-requisites
- Programme responsibility: The SIT scenarios specified by the Systems Integrator (SI) team, demonstrating functional, non-functional and migration-related characteristics of the Market Interfaces and Services in an integrated environment.
- Participant responsibility: Evidenced Pre-Integration Testing (PIT) executed in your own environment.
Defect Management Plan
The Programme has baselined the Defect Management Plan which is available below:
The document describes the overall approach to managing defects within the industry testing phases of the MHHS Programme. The purpose of the plan is to support the timely and efficient raising, triage, categorisation, and resolution of defects.
It also describes the defect assignment and process workflow, along with state definitions and transition states.
