Hi Micha, thanks for your very interesting feedback. I want to react to some of your propositions:

You say: "At the end of the day, a designer can do good things if the environment he is part of is good and supportive as well."

That is very true and in my experience it's the most common obstacle to doing good product work. I also think that we (product people that understand the craft) have an important role to play in trying to improve this environment.

You said: "Articles like this are unfair. There is no good or bad, right or wrong."

I am not arguing that being bad or wrong is a permanent state at all. Actually quite the contrary. But in order to get better and progress, you need an idea of what is good or bad. This is what I try to provide in the article: examples of classic Do-s and Dont-s. Could you expand on what you think is unfair? What I understand of your point of you so far is: you think that setting expectations is unfair because some people are more skilled in some areas, and less in others. Is that correct?

You said: There are great designers that are introvert by nature and might not be 'good' at presentations and collaboration but are amazing in ideation and solving complex problems.

Of course. But they would be even greater designers if they got better at other aspects of the job.
