This paper will first take a look at what kind of services onboard diagnostics and monitoring offer. This is done by briefly looking at both the automotive and the aviation industry. Following this, a closer look is taken at the potentials of such systems. Particular attention is given to potential benefits of onboard diagnostics and monitoring in connection with other backend systems. Again, the paper takes examples from related industries (namely aviation and truck fleet management) to generate ideas. Finally, a look is taken at the impact that the realization of the full potential of onboard diagnostics and monitoring might have on the enterprise IT infrastructure, particularly related to enterprise IT systems such as data warehouses or data marts for vehicle data.
