Thankfully my direct manager/leader has never been one that talked their way into the job. So explaining what I do has never been an issue.

However, when I was a technical manger, explaining a technical matter to the managing director was quite a challenge. He came from the sales side of the business. He had sold technical products all his working life but like to push technical matters to one side in favour of business matters.

He always listened and I am pretty sure understood most of what I said but I am also pretty sure that I was not 100% successful all the time.
