That’s right, it’s certainly not a good idea to leave the head of department out of the loop - this position should definitely be informed about every relevant process. I just think that it’s in everyone’s interest if senior management can be seen by the “common people” from time to time. It shows appreciation for the work and opinions of all employees and is also a good opportunity to make sure that no important aspects or overly technical details may have been lost on the way from the head of department to the executive floor. Just as you say.
