The German has arrived on Tyneside promising a more vertical approach, with Newcastle encouraged to attack quickly, compete for second balls and press opponents aggressively.
Jaissle believes that approach can produce both attractive football and winning results, although he accepts that achieving the balance is one of the central challenges of his new role.
"In the ideal world, there is not too much difference, that's also the reason why I am here and why the club signed me," Jaissle said.
"The club is striving for a clear identity and, fortunately, a playing style, independent of who the coach was in the past years. Therefore, I think it is a great fit for me."
Jaissle believes the existing Newcastle United squad is already suited to his methods, with the summer recruitment also allowing the club to introduce younger players.
"What I mentioned (vertical football), it is the same approach, which is the good part, because the players who were already here fit into that style," he said.
"In the summer, we made a couple of adjustments, although we signed younger players, but that is exciting."
The challenge is not simply to attack. Jaissle wants Newcastle to retain a competitive edge without abandoning the identity he wants to establish.
"As a coach, you have a clear identity and clear principles, and I used to say a 4-3 win was nice, it is entertaining for the fans, for you guys in the media, but for the coach, not necessarily so," he said.
"Of course, you want to score a lot of goals."
Jaissle also made clear that the ideal performance would combine attacking ambition with defensive control.
"In the best scenario, you want a clean sheet. Is that always realistic (a clean sheet)? No, but of course, you have the perfect picture and perfect game in your mind," he said.
"You try to be at least as close as possible in your mind."
The Newcastle manager has previously explained that his definition of vertical football is broader than simply playing long balls.
He wants his players to look forward quickly after regaining possession and to identify the deepest available option.
"That's just the principle, being vertical in your approach," he said.
"So that could be that you go straight away for the long ball, that you don't even try to play out from the goalkeeper, just going for the aerial duels there.
"But that could be also that you have just the intention to have always the first view deep, try to find the deepest option."
Jaissle also wants the same mentality to apply immediately after Newcastle win the ball.
"The players' mindset after collecting a second ball, after winning the ball, that the first view is deep, that you have that vertical approach - that should be always there."
His early reception from Newcastle supporters has also made an impression. After fans unveiled a banner welcoming him before the season had properly begun, Jaissle invited the Wor Flags group to the training ground to thank them personally.
"Yeah, you can imagine that gives me a great feeling, and I appreciate that a lot," he told Chronicle Live.
"I thought it was a special thing to do after such a short amount of time."
Jaissle's task now is to turn that early enthusiasm into a Newcastle side capable of delivering the identity and results he believes can coexist.
