John is no lone wolf but a team player who has always shown an interest in the work of others and been happy to provide advice beyond the immediate area of expertise required by his position. Tell your marketing department to look to their laurels, because this is one aspect of your business in which John will be keen to get involved. In particular, if it's rebranding you want, he has no shortage of ideas for this tricky area. Do you have a flag? That's what you think.
If John has an area in which there is room for improvement it might be that he sometimes allows his heart to overrule his head. It's a tendency that has seen him advance the careers of others when they were not - in fact, probably would never be - ready for it.
I'm thinking for instance, of an employee whom I'll call "Gerry". Gerry was struggling when John took a chance and gave him a hand up. It was a real "Awww" moment for all of us, and we can only regret that John will not be here to see that effort though to its conclusion, if there ever is one.
If there is one quality above all others that John brings to the job it would have to be empathy and an ability to put into words what others are feeling. When he told us that his incumbency had put a strain on his family, thousands of other families around the country, hearing the news in the motels and garages where they live, understood exactly what he meant.
One of John's greatest gifts is his ability to stay focused on the here and now. He is a forward thinker, always concentrating on the path ahead rather than the road that got him there. If that means he tends to be forgetful about past statements or positions on various matters, we can only point out that it's called "the dustbin of history" for a reason.
John is not stubborn, nor does he blindly insist on following a path just because he has made an undertaking to do so. If he had that sort of personality, many things would be different. To name just one, this country would still have a 12.5 per cent goods and services tax.
Finally, I would like to sound a word of warning about the context in which this reference should be read as I'm aware it may seem a little fulsome in its praise. If that is so, it is only because our views are coloured by our memories of trying to work with John's predecessor.
