Alan Curbishley insisted stability breeds success, on The Footballers' Football Show.
The former Charlton boss - who spent 15 years in charge of the Addicks - says short-termism in football is hindering clubs throughout the country.
Currently 52% of clubs in English football have a manager who has been at the helm for less than one year, while eight bosses have been axed in the top flight during this campaign, one shy of the Premier League record.
Those figures demonstrate the extent of the problem, says Curbishley, who was technical director at Fulham during Rene Meulensteen's brief reign this season.
"Longevity brings a lot of plusses to the manager, to the board and to everybody," he said.
"You've got to be thinking long-term - but managers can't be doing that because the stats are telling us you're not going to be around that long.
"Once you get into the job you have to be successful straight away these days - and that's the problem in football, although things are a lot more stable in the lower leagues.
"In the top two leagues if you're not living up to the expectation levels - which may be wrong - the manager is in trouble.
"And as we've seen this season, at any club which falls into the bottom three in the Premier League, the manager is in big trouble."
Instead, Curbishley says clubs should look to the success he enjoyed at Charlton - where he steered the London side to two promotions to the Premier League - as an example of what can be achieved with stability.
The trust he received from his board, he told The FF Show, allowed him to tackle both short and long-term goals.
He said: "There was one year when I wanted to sign Jorge Costa on loan from Porto because I felt he could help us stay up, which he did.
"It was a massive loan fee, massive wages, but we went into that because the board trusted me and we were struggling a little bit.
"Then I signed Jerome Thomas from Arsenal for £100,000 for the future.
"I could go short-term and long-term because I'd earned the right. When you've been around for a long time the board trust you and know you're doing everything for the right reasons.
"Unfortunately, with the managerial changes we're getting, the short-termism comes in and I can bet you any manager that's arrived mid-season can only be thinking about the next six months. His priorities are not about the future of the club, it's about now."
Paul Tisdale, who has been in charge at Exeter for eight years, says the problem is particularly troublesome for young managers.
He says he was almost put off management by his experiences as a player but the support he has received from the Grecians's board has allowed him the opportunity to improve, which he doesn't feel he would get at a higher level.
"At the start I was put off being a coach or manager in the first place because of my experiences as a player at Southampton - in seven years there I had seven managers and never had the feeling that I had the opportunity to come through," he said.
"But I got into it because I wanted to coach and learn coaching and make it my craft.
"It's my 15th year now and I'm still learning. Dropping in at the top level, when you have less time, surely makes the chances for being successful slimmer."
