Scheduling job to run after another finishes

Is there a way to schedule a job to start after a different one finishes? For example, I want to run an archive job on my regular mailboxes, then when that completes I want to run an archive job on the UDA folders. We're archiving a small number of users (although that number is growing).

I don't know if the "best practice" would be to schedule those for different days, or if you schedule one to run at 10:00 at night and start the next one at 11:30 assuming the first job will be done (that sounds scary) - it would be nice if there is a way to specify that when Job A completes, Job B will start, or if there was a nice document that I haven't found lining out what the best practices are related to scheduling jobs.

Thanks!
