Annotation

This module specifies the process to:

a) measure asset-related data and information to check they meet the agreed quality criteria;

b) identify data which does not conform to the quality criteria requirements;

c) publish the required conformance reports, to enable identification of the relevant data and the nature of any error detected, for example:

1) the types of error;

2) the number of instances it has occurred, both quantity and as a proportion of the measures conducted.

This module applies to:

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

b) measurement of asset-related data from those individuals and organisations external to the asset management system, for example, asset data used in financial calculations; and

c) projects measuring asset-data for an appropriate level of quality.

It does not apply to data related to non-operational assets such as IT and office facilities assets. This module applies when new or modified data is received from:

a) projects performing enhancements and renewals, and or modifying assets and asset-related data and information;

b) maintenance activities for physical assets; and
