This module specifies the process to define and agree asset-related data quality and information quality requirements.

This module applies to:

a) the entire asset management capability as defined within Network Rail’s asset management strategy, both internal and external to Network Rail throughout the lifecycle of asset data;

b) the delivery of requests and requirements for asset-related data from those individuals and organisations external to the asset management system e.g. asset data used in financial calculations; and

c) projects delivering asset-data related applications and solutions to define and agree asset data specifications and appropriate measures of quality.

This module applies when:

a) defining the asset data required to comply with Network Rail asset standards and regulatory requirements;

b) defining the required asset-related information needed for business planning, in financial processes, asset management, and asset maintenance planning;

c) defining the accountabilities for data and quality criteria to be collected through asset maintenance, renewals and enhancement activities;

d) identifying who may review, agree and sponsor proposed plans and remediation solutions to address existing data quality issues

Purpose

This module describes the Data Flow Management process to:

a) identify and document how, where and who are the users of asset-related data;

b) to assess the impact of changes across the data and system landscape; and

c) identify who is the accountable and involved parties to agree the appropriate quality of asset-related data to understand whether data is fit for purpose, and impacted by changes to the data.

The Data Flow Management process described in this module supports Network Rail in realising principles in NR/L1/ADG/001 which set out how Network Rail:

a) applies and maintains metadata for unstructured asset-related data and information in alignment with the national requirements;

b) maintains data so that it is accessible to users;

c) maintains and disposes (archiving) of data traceable to and from the information and reporting requirements

The process described in this module is a mitigating activity to address asset-data related hazards:

a) recurring data errors issues occur;

b) failure to provide an effective data improvement plan

c) erroneous data accumulates and persists; and

d) structural inability to implement schema across the enterprise systems.

This module forms part of the quality management system for asset-related data, which interfaces with these processes and related management systems (nonexclusive):

a) Asset Management System;

b) Training and development (HR);

c) Solution architecture governance; and

d) management systems impacted by the proposed change (e.g. IT system management, people / organisational management)
