The invention proposes ascertaining at least one technical influencing variable for the technical measured variable and then identifying design measures on the installation which are able to influence the at least one technical influencing variable such that the value of the at least one technical measured variable is altered so as to increase the value retention of the installation. In a subsequent step, further technical influencing variables for the value retention of the installation are identified which have their value altered by the design measures. Thereafter, the changes in the values of the technical influencing variables on account of the design measures and then the change in the value retention of the installation which is linked to the changes in the values of the influencing variables are ascertained.
