Bayern continued their charge to the title at the weekend as goals from Mario Manduzkic and Thomas Muller handed them all three points at the Mercedes-Benz Arena.
Although the result was their second consecutive 2-0 win following victory over Greuther Furth a week back, Heynckes had been unhappy with his side's display in that game and was pleased with the way they responded against Stuttgart.
"We were significantly better than against Furth," he said. "My team were very composed for the entire 90 minutes and totally focused right from the first whistle.
"Our shape and organisation were excellent, our movement was tactically very good and we afforded [Stuttgart] almost nothing in attack. But in the first half, we just lacked a little flair, determination and urgency."
Heynckes did however reveal that a spirited halftime team talk was just the right tonic his side needed as they raised their game in the second half to see off their opponents.
"We failed to find the final pass, cross or shot at goal," he added. "I complained about that at halftime and we were much better in the second period.
"Stuttgart pulled everyone back so it was never easy, but that's when you have to raise your game, which is what we did in the second half. Ultimately, you force your opponents into errors."
Bayern have picked up 48 points from 19 games and are currently 11 ahead of second-placed Bayer Leverkusen.
