Or if you mean how to improve the shuttle we actually got then the answer is LRBs.
The SRBs generally took about 3 weeks to stack in the VAB and required the halting of various other tasks throughout the entire building (most importantly: stacking the external tank and the orbiter, even in other VAB cells) and this meant that the maximum possible flight rate was some place in the mid teens.
Introduce liquid boosters (with an assumed stacking time equal to the ET/orbiter) and no other work has be paused, multiple shuttle stacks can be processed simultaneously and the maximum theoretical flight rate shoots up to about 50 per year.
At this point orbiter turnaround is the primary barrier to higher flight rates, order another orbiter or develop shuttle-C and then I think annual ET production becomes the limit.
