        "description": "The NorTMS Audit is to undertake audits as required of the Northern Transport Modelling System (NorTMS), a Cube-based VDM with a focus on intercity rail in the North of England. These will be required on a call-off basis when a stable model release is available. After each audit the supplier will be expected to provide an audit report with recommendations for areas requiring improvement. This will be subject to a one+one+one year call-off basis. TfN requires a supplier who is an expert CUBE model reviewer with competent Python skills as some elements of NorTMS are coded in Python, and who has not worked with NorTMS or related to any TfN framework directly involved in NorTMS, unless the work that was delivered relates to the audit of NorTMS. The scope of work required for each NorTMS audit underpins the following objectives: *Provision of a full audit of all NorTMS inputs and outputs with the aim of instilling confidence in NorTMS for its use in modelling works and supporting business cases. *A review of each version of NorTMS following model updates and improvements prior to implementation on programme. *To understand the fitness for purpose of NorTMS in its use for assessing schemes for Northern Powerhouse Rail (NPR). *Production of a comprehensive audit report giving a RAG rating of all the model elements reviewed. *A final report comprising of a plain English summary of issues identified (for a general audience) and a detailed technical report (for a modelling audience) with potential recommendations for areas requiring improvement, an outline of best practices in CUBE and the application of CUBE as a modelling tool.
