The invention relates to a teamwork method and a computer system, using which the evaluations of a group about the features of different targets can be gathered and summarized. The system comprises a server (1), the workstation of the main user (3), a number of workstations for evaluators (4-7) and the software used by the web-browser. The main user formulates the inquiry. The server requests through email the evaluators to answer it. The evaluations are entered graphically using a two-dimensional table. The axes of the table present the dimensions to be evaluated. The program calculates normalization for the answers given so that the mean value is located in the origin. When a report is requested the server calculates the normalized mean-value figure, places the points in the two-dimensional table and adds ellipses around them, the dimensions of which present the deviation of the points in the direction in question.
