In-house training will be of great value to your business partner, and reduce your own costs. You can also suggest this during the negotiating process. Because of the Polish law's complexity, contracts and technical and commercial documents, such as a feasibility study, will be very detailed. You should document agreements precisely so that you have some protection should the law change. Polish managers do not spend much time on small talk, even at the start of a relationship.
Negotiations tend to be unemotional and directed towards a goal.
Because Polish managers may be unfamiliar with the range of commercial techniques, your negotiating partners will probably find it hard to react in a flexible way when something unexpected crops up. As well as this lack of flexibility, which may be severe enough to wreck the negotiating process, managers have to observe complex procedures if they want to secure the permits and licences that many deals require. In order to get these, you will have to approach the public authorities, which are still rigid, poorly motivated and extremely slow. That way, you can accommodate any delays caused by the authorities, and respond to any of their demands. When negotiating with Polish business partners you will usually communicate in German or English.
