The invention relates to a method and a device for determining the causes of malfunctions and performance limits in installations. It is difficult to determine the causes of disturbances and/or performance-limiting factors in complex installations (15). The inventive method allows malfunctions in an installation (15) to be eliminated and/or the performance thereof to be increased in a lasting manner and with relatively little effort. Said method comprises the following steps: data (51a-i) is provided on causes of malfunctions and performance limits in a plurality of installations (40a-c); a questionnaire 26) regarding said causes is created from said data; replies (27) relating to the questions of the questionnaire (26) are solicited from employees (29) working in the installation (15) that is to be diagnosed; and the causes of malfunctions and performance limits of the installation (15) that is to be diagnosed are determined by evaluating the replies (27) supplied by the employees (29) regarding the questions of the questionnaire (26).
