A method for operating a laboratory system comprising instruments for processing samples and a control unit connected by a communication network is presented. The method comprises receiving and identifying a biological sample and retrieving an order list from a database. The list comprises a plurality of targets defining one or more processing steps to be carried out on the biological sample by one or more of the laboratory instruments. The method also comprises selecting a workflow strategy and retrieving workflow acceptance criterion corresponding to the workflow strategy. The control unit determines a sample workflow for processing the sample based on the workflow strategy and determines whether the sample workflow satisfies the workflow acceptance criterion. If the sample workflow does not satisfy the workflow acceptance criterion, workflow strategy and the workflow acceptance criterion is refined and the sample workflow is determined again until it satisfies the workflow acceptance criterion.
