The invention concerns a conveyor lane divider for dividing trays that are received in one lane from an infeed conveyor and are passed on to a two-lane production unit. A system for evaluating the craftsmanship of an article of manufacture may include a list of components to be evaluated, a list of attributes by which the components are to be evaluated, and a report providing a quantitative score of each component according to each attribute. The system has a plurality of software layers to process the errors. In operation, security users of the SIEM system execute the workflows including the respective security business objects, resulting in a set of result data which identifies security threats and vulnerabilities of the production computer system.
