Jackett replaced Dean Saunders in June after leaving Millwall at the end of last season and saw his new team beat Livingston in their second pre-season friendly match.
Jackett told the Birmingham Mail: "Winning is a habit that we want to build up. Perhaps to some degree the club got out of doing that.
"In terms of the team we are a work in progress, there's no doubt about that. Once the players understood what I wanted today we saw some good things.
"We created a lot of chances and had a lot of shots. We are on the right lines but we have to keep working hard.This gives us something to build on."
