A method and a device are proposed for determining parameters describing changes in a technical system caused by ageing, usage-dependent performance quantities being ascertained in the system. In this context, using a wear and tear model, a correlation is produced between the ascertained performance quantities and the parameters describing changes in the system caused by ageing, and subsequently these parameters, or quantities derived therefrom, such as remaining service life, probability of malfunction, or quality of a product, calculated internal to the system at any point of time as desired.
