management, network occupancy, customer service... In each case the format of the information and the timeframe of the alerts are adapted to the needs of the business user. The information flowing through the Data Warehouse


can also be used ‘off-line’ to produce performance reports or dashboards. Performance dashboards are interactive reports that allow users to identify high level trends. The details in the big picture can then be easily accessed by using a drill through method, thus allowing managers to quickly iden- tify the root causes of any negative performance pattern to address them. Information can be rendered in common for- mats, Word, Excel and PDF, etc and delivered typically via an auto generated email or published on Microsoft SharePoint, the content management system. This solution has been suc- cessfully used on the M25 to drive its performance up and achieve most of its 300 Key Performance Indicators. The Data Warehouse manages processes that collect data

from across the M25 network, which effectively includes any electronic data generated by the operation, whatever its format and location on the network. A process or job is designed to run automatically at specified intervals and is cumulative; meaning that a new set of information is added each time the job is run. This type of data can be used for reports that show metrics, trends, aggregations, and other relationships among the data. Data is cleansed, validated and formatted before it is used to feed the business and contractual reporting requirements.


IN THE INCIDENCE OF INCIDENTS Any failure of the information system on the M25 could have an immediate adverse impact on performance. In the case of incident management, any delay in the response could result in secondary accidents or important conges- tion. To add resilience to a process, the Data Warehouse is
