Effective communication with attention to detail

How to be connected with your interlocutor, hear the other side and achieve your goal...

Human Intelligence (HUMINT) means gathering unique and valuable intel through human sources. With human intelligence, existing (open) information is enriched and validated - or even completely new insights may be acquired. But how do you get to the point where someone surreptitiously provides information to you, while possibly exposing themselves and their environment to risk? Extracting detailed information is done on the basis of trust. Therefore, you have to know and understand the other, as well as yourself. During the 'HUMINT, Communication & Engagement course' of Triangular Group Intelligence (TGI) you learn how to achieve your goal by effective communication.

The course takes 2 or 3 days at our training location in Heerle and is also offered incompany.

Our clients say

I have never followed such a nice training before! The variety was good, but especially the surroundings, the trainers and the other staff were super. It was also very nice that both Ray and Onno visited us and were genuinely interested in us. We were not just a number. For me, this week has really given me a lot. I have grown in knowledge, but also personally this training has brought me a lot.
