Trixi Hauptmann Product Manager, Haufe umantis AG

"Dear Frank,

many thanks for the great training!

I am still enthusiastic and use the materials practically all in daily business. Not everything every day, depending on the needs and phase. This gives me a standard that I can still adapt to my needs. But it is precisely the start into this tool use that is important and that motivated me a lot.

Super basis to position yourself in the product manager universe and to go in the right direction.

Meanwhile we have already conducted a lot of customer interviews to get to the bottom of the needs of our customers.

This is not easy because customers often say what they want from their daily work and you have to dig to get the actual motivation for those wishes. Then a different solution than the one suggested by the customer can be the painkiller to finally inspire the customer. That makes it extremely exciting.

Thanks again"
