Die emphatische, zielorientierte Zusammenarbeit mit Tim Wisiorek während unserer gemeinsamen Zeit kann ich besonders hervorheben, da innerhalb kürzester Zeit, innovative Beschaffungskonzepte als auch effiziente Einkaufsorganisationsstrukturen in einem internationalen, agilen Umfeld erarbeitet sowie aktiv unter seiner Leitung implementiert wurden.

Ich habe dabei die transparente, individuelle Kommunikation sowie perspektivische Lösungsfindung während dieser Organisationsentwicklung mit Tim Wisiorek sehr wertgeschätzt.

Ich habe Tim als eine integre und engagierte Führungskraft im Einkauf kennengelernt, die ihre Mitarbeiter gleichermaßen fordert und fördert.

Mit seiner Fähigkeit, die Bedeutung der Einkaufsentscheidungen im Gesamtkontext des Unternehmens klar und transparent zu vermitteln, schafft er Vertrauen und hält die Motivation im Team stets auf einem hohen Niveau.

I have had the pleasure of working with Tim over several years. In that time, we traveled extensively in Europe and China and had many successful collaborations.

Tim is knowledgeable, well spoken, and possesses a high degree of business acumen.

I can only comment on his leadership through my interactions with his subordinates which, in my opinion, was very good as it was clear his team respected his leadership and was thankful for his mentorship.
