While Murray had already previously climbed to World No 2 before appointing the Czech 18 months ago, his record since then - Olympic Gold, US Open Champion and now Wimbledon Champion - owes a great deal to the Scot's successful relationship with Lendl.
The can be no doubt that Murray already had what it takes to succeed. Lendl helped bring it to the fore. He did what every great coach in any walk of life does: helped Murray to clarify his goals, and helped him draw on his own strengths to achieve these goals.
In that way, Lendl has achieved what every coach strives to do - he has helped to unlock Murray's potential.
Murray's journey is something that many leaders in the business world can relate to. He has gone after a goal and fought hard to achieve it. He has had some very difficult periods and overcome many challenges. He has enjoyed widespread support and also come in for a lot of criticism. He has carried the weight of expectation.
Speaking shortly after lifting the trophy that has eluded men's singles players for more than seven decades, Murray was quick to praise Lendl for his honesty.
"He's made me learn more from the losses that I've had than maybe I did in the past," Murray said. "He's been extremely honest with me. If I work hard, he's happy. If I don't, he's disappointed, and he'll tell me.
"And when I've lost matches, last year after the final he told me he was proud of the way I played because I went for it when I had chances. It was the first time I played a match in a grand slam final like that. He's got my mentality slightly different going into those sort of matches."
This approach would clearly have helped Murray bounce back from the disappointment of last year's Wimbledon final to winning gold at the Olympics four weeks later. By speaking from experience, Lendl could also reassure Murray about how to handle the nerves of playing in a grand slam final - which paid off in the US Open last September - and the fear of what might happen to his life if he did succeed.
This focus on learning from losses not only helped Murray focus on continual improvement, but ensured he did not dwell on disappointing experiences, but drew on them and learned lessons which helped him to succeed next time.
There is clearly a mutual respect between Murray and Lendl. Murray has said that his coach "brings experience and knowledge that few others have, particularly in major tournaments". Their partnership demonstrates the power of collaboration.
In the business world, coaching has grown in popularity. However some leaders still see the need for a coach as a sign of weakness. The relationship between Murray and Lendl demonstrates that a great coach can nurture great strength.
