Pause the 'Complete' status of the scripted OS install job

I'm new to Altiris and I'm trying to figure out how to pause the 'complete' status for the scripted OS install job. I want to chain a set of jobs (OS > SP > AV > Office > etc.) after the OS is fully installed, but the job reports 'complete' to the console while the OS is still installing; thus moving on to the next job and failing.

I tried the tip about adding a production run script job with a "echo complete" line of text, but the OS install job still reports a completed status when the installation still has 45+ minutes to complete. Is there another way to achieve the chain install sequence I'm looking for?

TIA
