Gillingham boss Steve Lovell was delighted after their dominance was finally rewarded in the second half on Saturday.
Lovell was thrilled with his team's performance - and knew that they should have won by even more goals.
"I'm happy with the victory, and the way we got the victory," said Lovell. "The way that we played, the way we passed the ball, the chances we created, and the way we defended - it was probably one of the best performances of the season by the players.
"It's a great result. It could have been a lot more and I don't think anyone in this ground could have argued with that."
Scunthorpe have only won twice at home in League 1 this season - and they never looked comfortable against a lively Gills attack.
"We knew that they haven't had the best of records here at home," added Lovell. "It's hard when you are losing games to lift players, but you've got to give our boys credit for the way we played.
"We didn't allow them to play that well. When we got the ball we used it and created loads of chances.
"Tom Eaves could have ended up with four, Elliott List could have got three, and along with Josh Parker them three were brilliant. They caused so much havoc for their back four."
The teams went in at the break goalless, but Gills added a clinical touch in the second half.
"I said to carry on doing what we were doing," said Lovell. "There was no need to change anything, the only difference was that we hadn't stuck the ball in the back of the net.
"I said it will come, if we keep playing and creating chances then the more chance we had of scoring - keep getting the ball to Tom, Josh and Elliott.
"It's the manner of the win. It's lovely to get three points but you can go to places, get three points and say you were lucky - not today, we thoroughly deserved to get the win."
