Lets do Some Word association...

StartTrek TNG is to Star Trek as Journeyman is to Quantum Leap!

Let's review the facts.

NBC owns Quantum Leap and Journeyman.

The show by show outline is the same. Man goes back in time, man saves other human.

In Quantum Leap, Sam's quantum project is being shutdown as a failure. To save his funding Sam test's his work on himself prematurely and starts jumping from one person to the next. Each time with partial amnesia.

Now It's a bit early to say only having seen two episodes and all but I have a theory.

After Quantum Leap ends. The project is perfected. Allowing people to jump without taking someone else's body, Or placing the person in the machine(this is supported in Quantum Leap when Sam jump from person to person without going home first).
