“What’s the point of deliberating and beating around the bush? The point is simple and everyone can see it: it is badly done and needs to be corrected. End of conversation – everyone can get back to work.”
Well, Ok then. This may indeed end the discussion about this topic, but it can also signal the end of cooperation on the entire project. Contrary to appearances, direct feedback is frowned upon in many cultures. Hence, for example, the so-called the “s#%t sandwich” technique (one negative piece of feedback sandwiched by two positives) when giving feedback.
In a nationally and culturally diverse environment, it’s good to know who belongs to which culture. This can save both parties a lot of stress. Ideally, it would be nice to know who has what approach to a given topic. Then you can consciously avoid problems and try to tune each other out.
