A person business and technical acumen are very important in term of relation to deals. Each party is taking a risk for each other to work together, and the knowledge provides confidence that the deal will be executed effectively. The interpersonal add the quality factor into a deal. For example, when interviewing for a job the interviewer also access your thought process and your ability to communicate with others, this is to see if the person would actually work with the person. This goes for this example as well, the supplier or any other entity working with the company wants to know if their deal will be executed in a proper manner. The combination of the two initiated a lasting partnership that shared both confidence and quality in the implementation of terms. Another important aspect is that the two properties provide a safety net for the other, for example, if for some reason there is a technical issue, the excellent interpersonal skill of an engineer can help deal with the issue. On the other hand, if for a small reason the communication was negatively affected; a history of good technical efficacy can help maintain that relationship. This is seen where I worked, small mistakes happen and having a good history with another person/entity can help keep those business relationships.
