A method of acquiring problem descriptions and of determining solution proposals in a system comprising at least one server device and at least one client device, wherein the client device may be coupled to the server device via a communications network, wherein the server device is coupled to a storage device in which a number of problem descriptions, a number of parameters, and a number of solutions are stored, wherein the problem descriptions have each at least one parameter and at least one solution associated therewith, wherein the parameters associated with a given problem description give an outline of said problem description, wherein the problem descriptions comprise clinical pictures, wherein the parameters comprise symptoms, wherein the solution proposals comprise therapeutic proposals for the treatment of at least one clinical picture, and wherein the server device a) transmits a number of parameters to the client device, inviting a user to select at least one parameter, b) receives the at least one parameter selected by the user from the client device, c) selects those problem descriptions from among the stored problem descriptions with which the received parameters are associated, and selects, from among the parameters which are associated with the selected problem descriptions, those parameters which are not identical with the parameters already received, d) transmits the selected parameters to the client device for selection by the user; e) repeats steps b) to d) until there are no more parameters available for selection in step c) or until the server device receives a termination signal from the client device, f) determines the solutions associated with the selected problem descriptions and transmits them as solution proposals to the client device, inviting the user to select a solution proposal, receives the solution proposal selected by the user, stores the received solution proposal, together with a user identifier, in the storage device, and associates the parameters received in step b) with the stored solution proposal, and g) receives a message from the client device which contains information as to whether using the solution proposal selected by the user has brought success, wherein the server device receives at least one status message from the client device which comprises information on whether, and how, the parameters received in step b) are subject to change by application of the selected solution proposal, wherein the change of the parameters over time is stored in the storage device and associated with the selected solution proposal, wherein based on the change of the parameters over time, a weighting factor is determined for the selected solution proposal and is associated with the selected solution proposal, and wherein the change of the parameters over time is used to determine whether the solution proposal is appropriate and well-targeted. a) transmits a number of parameters to the client device, inviting a user to select at least one parameter, b) receives the at least one parameter selected by the user from the client device, c) selects those problem descriptions from among the stored problem descriptions with which the received parameters are associated, and selects, from among the parameters which are associated with the selected problem descriptions, those parameters which are not identical with the parameters already received, d) transmits the selected parameters to the client device for selection by the user; e) repeats steps b) to d) until there are no more parameters available for selection in step c) or until the server device receives a termination signal from the client device, f) determines the solutions associated with the selected problem descriptions and transmits them as solution proposals to the client device, inviting the user to select a solution proposal, receives the solution proposal selected by the user, stores the received solution proposal, together with a user identifier, in the storage device, and associates the parameters received in step b) with the stored solution proposal, and g) receives a message from the client device which contains information as to whether using the solution proposal selected by the user has brought success,
