Evaluation Survey


Wer möchte, reist bis 22 Uhr am Vortag an und nutzt den Abend bereits zum Fachsimpeln am Kamin oder im Park.

An den Kurstagen dann von 9-18 Uhr (mit 2 Kaffee- und 1 Mittagspause) etwa 60% Schulungen und 40% Übungen. Selbstverständlich arbeitet jeder Teilnehmer am von uns gestellten Notebook oft parallel zum Referenten mit.

Anschließend Abendessen und Angebote für Fachsimpeln, Ausflüge uvm. Wir schaffen eine Atmosphäre, in der Fachleute sich ungezwungen austauschen. Wer das nicht will, wird zu nichts gezwungen und findet auch jederzeit Ruhe.
