Transaction data is generated during monitoring of a plurality of transactions in a system and a respective flow is determined, from the transaction data, for each of the plurality of transactions. Each of the determined flows involves participation of a respective subset of software components of the system. A plurality of sets of overlapping flows in the plurality of flows are determined and a particular one of the plurality of sets of overlapping flows is determined to correspond to a use scenario of the system. A measure of the degree to which a set of artifacts modeling the system corresponds to the use scenarios of the system is determined.
