I just ran the numbers. These are the GMA correlations with an equally-weighted combination of all other instruments of the first three stages (form, CV, work test(s), two interviews). Note that this make the sample size very small:
Research Analyst: 0.19 (N=6)
Operations Analyst: 0.79 (N=4)
First two stages only (CV, form, work test(s)):
Research Analyst: 0.13 (N=9)
Operations Analyst: 0.70 (N=7)
I think the strongest case is their cost-effectiveness in terms of time invested on both sides.
