If I were in the position of designing policies, I will not let anybody escape from being evaluated from "bottom" to "top" or from lowest status to highest status be it in an industry or in a business or in a university. Everyone has to hold the responsibility for the undertaken decisions & actions.

The person will be given 100 days starting from the date of occupying a post & then the process of evaluation will commence. Evaluation will look at the input or resources that are available & at the output or outcome. It has to put aside all the misinformation & advertisements that aimed at "blowing" some figure or some company. The mechanism ought to look at merits only & all will be held into account.

I know that I may seem "idealistic" but I think that it is "too realistic" since this will rectify the mess that is going on unabated in many circles in the world of today.

In addition to what I stated above, there are anomalous practices that are observed in some places.

Firstly, the person who is appointed at the top managerial post will be tempted to think that the corporation has become his/her private farm if given an overwhelming authority. This "dictator" will devastate the firm since the decisions & actions will be shaped by egoistic personal considerations. Consequently, this person has to be evaluated first & foremost. S/he must be held accountable.

Secondly, it is tragic to see persons evaluating those who are more experienced & more mature than them. I will not blame an older when s/he asks the one who evaluates: "Who are you to evaluate me ? Who are you to promote me? And who are you to relegate me?".

This question by my RG colleague is really important & it ought to be discussed by more participants.

The methodology we will use for this evaluation is a comparison to professional reference equipment available at the University of Stuttgart and a comparision to professional equipment used by the local authorities. The local authorities do measurements for legal reasons to ensure compliance with EU legislation with respect to the air pollution limits. However, we will also do a comparison between different brands of PM-sensors. What we are also looking for is the option to do a compensation for some of the inaccuracies that we will determine.

Dear Bernd, Thank You for Your answer.

Me too believe that this is probably the best way to proceed for a comprehensive and fair comparison. The EuNetAir intercomparison excercise has followed the same approach:

as per compensation methods. Since 2007, We propose the use of data driven, on field calibration methodologies for this specific task. A comparison of ML techniques can be found in:

However robusteness of the methodology has still to be fully clarified, see:
