COMET benchmarking

The four main objectives of the metro benchmarking groups are: # To share knowledge and identify best practices in a confidential environment # To support members in achieving their operational and strategic goals – focusing on improvements # To build systems of measures for use by management and to establish public transport best practices # To prioritise areas for improvement and support decision-making for management, boards, government, and other stakeholders The key performance indicator (KPI) system is used by the COMET during the benchmarking process in order to compare performance across the member metro systems. The purpose of benchmarking is to search for best practices that lead to superior performance. There are approximately 30 top-level indicators, which are designed to measure the overall performance of the organisation in six distinct areas: * Growth, learning, and innovation * Financial * Customer * Internal processes * Safety and security * Environment The indicators are reviewed by members on an annual basis. The group members operate under a full confidentiality agreement. This allows for full data and information exchange within the COMET but not externally.

Statistical analyses Statistics (from German: ''Statistik'', "description of a state, a country") is the discipline that concerns the collection, organization, analysis, interpretation, and presentation of data. In applying statistics to a scientific, industria ...

are used to provide greater understanding of the results, while time series analyses allow for trends in performance to be identified. This helps to highlight which members are changing their practices and what improvements are relatively achievable. Where clear differences or improvements in performance are identified, detailed analysis is carried out through case studies. Multiple case studies are conducted in the COMET each year; these studies include detailed data analysis, questionnaires, and interviews with functional experts. Case studies are further supported by expert workshops where appropriate. In many cases, best practices may be found outside the metro industry, so other public transport operations and even other industries are reviewed for relevant practices.
