# Commission Decision of 14 November 2012 concerning the technical specification for interoperability relating to the ‘operation and traffic management’ subsystem of the rail system in the European Union and amending Decision 2007/756/EC (notified under document C(2012) 8075) (Text with EEA relevance) (2012/757/EU), Division 4.2.3.4.4: Operational quality

Extent: E+W+S+N.I.

The infrastructure manager and the railway undertaking must have processes in place to monitor the efficient operation of all the services concerned.
Monitoring processes must be designed to analyse data and detect underlying trends, both in terms of human error and system error. The results of this analysis must be used to generate improvement actions, designed to eliminate or mitigate against events which could compromise the efficient operation of the network.
Where such improvement actions would have network-wide benefits, involving other infrastructure managers and railway undertakings, they must, subject to commercial confidentiality, be communicated accordingly.
Events that have significantly disrupted operations must be analysed as soon as possible by the infrastructure manager. Where appropriate, and in particular where one of their staff is concerned, the infrastructure manager must invite those railway undertaking(s) involved in the event concerned to participate in the analysis. Where the result of such analysis leads to network improvement recommendations designed to eliminate or mitigate against causes of accidents/incidents, these must be communicated to all relevant infrastructure managers and railway undertakings concerned.
These processes shall be documented and subject to internal audit.
