These modules apply to the entire asset management enterprise as defined within Network Rail’s asset management strategy, both internal and external to Network Rail throughout the lifecycle of asset data.

These modules apply to data related to all assets and to data that describes the operational railway (i.e. network models and attributes), but does not apply to operational geography related to infrastructure assets e.g. TIPLOC, STANOX and Network links.

It does not apply to data related to non-operational assets such as IT and office facilities assets.

Purpose

These modular standards set out the processes within the quality management system for asset-related data and information and for asset data governance:

• data quality planning – the process to define data and information requirements and to set plans to maintain the required accuracy of asset related data;

• data architecture management – the process to maintain the asset data architecture and at a conceptual level to meet business information needs;

• data stewardship management – the process to define the responsibilities for asset data and deliver a stewardship model;

• data flow management – the process to identify where and how asset related data is used and maintained throughout Network Rail;

• data design – the process to translate data requirements into logical and physical designs to store and maintain asset related data;

• data quality criteria set-up – the process to define the measures and method to (assess) the accuracy of asset related data;

• data error cause analysis – the process to perform root cause analysis of identified errors and issues and to develop remediation plans;

• data processing – the processes to collect, maintain and provide asset related data for reporting and use;

• data quality measurement – the process to measure the accuracy of asset related data;

• data error correction – the process to correct / fix asset related data issues and errors;

• verification and validation of asset related data – the process to perform self-assurance and cross functional assurance of the accuracy of asset related data and the effectiveness of the asset data governance framework; and,

• operate the asset data governance framework – the process to maintain and modify the asset data governance framework.
