This is an application which has been developed in order to provide measurements on the systems (devices) which are under maintenance and the activities which are being carried out. MS Excel files can be uploaded with the help of a new interface required by the application. Nineteen metrics can be filtered and queried based on criteria such as the work order date range, warranty/contract status, device type, model and system (device). These metrics cover measurements such as the ratio of faults eliminated without the need for field visits, the ratio of faults eliminated at first visit, material usage costs, average intervention and/or operating, or re-activating periods. Further, a device report card is created according to the total points calculated from the scores obtained from seven metrics for each device.
