Switching Programme Consequential Change Market Trials

As a part of the Ofgem Switching Programme, Xoserve and its customers will need to make system and process changes to accommodate the consequential changes required as part of this programme.

Consequential Change Market Trials will constitute of 2 elements:

  • Consequential change: testing any new or changed file formats, created due to CSS (but not with direct interaction with), ensuring that they operate, and new logic also operates as expected
  • Regression testing: testing of agreed critical functionality to ensure that changes made due to CSS have not impacted current functionality. It should be noted that this will be limited to the functionality which is considered to have been indirectly impacted and does not include an extensive testing of UK Link

The objectives of CC Market Trials are:

  • To fully prepare external parties and Xoserve for the introduction of the new and updated files aligned to the Consequential changes due to the CSS programme; ensuring that new logic is applied within UK Link and associated systems, verifying that Xoserve and industry systems work as intended.
  • To provide an opportunity for all participants to prove the systems and processes work by verification of their test scenarios through the execution of test cases.
  • The ultimate objective is to provide evidence that the system and supporting business processes function as expected and, where appropriate, support the E2E process developed through the CSS programme.
  • To provide the opportunity for Stakeholders and Xoserve to identify, address and resolve any issues prior to implementation to ensure the system is ready for Go Live.
  • To ensure the appropriate levels of testing to minimise risk to the CSS programme whilst ensuring that existing functionality has been protected.
  • To provide the outcome of Consequential Change testing to inform the overall CSS Go Live decision.
  • To provide all participating Stakeholders with the opportunity for familiarisation of new interfaces and, where relevant, all connectivity options in a production like environment testing functional data
  • To validate all record content in new and revised files recognising any revised logic being applied. It will be expected that all appropriate validation rules will apply.
