I think many of the estimates people have givin on this thread seem really high for the number of sysprogs to staff a z/OS site. At P&H, for the last 10 years or so, we had 3 sysprogs. We only had a 115 MIP machine, so were very small.
We're a small shop too. We run a z890-220 with 4 z/OS LPARs (monoplex). Each LPAR has from 4 to 8 CICS instances and between 6 and 13 ADABAS databases. We do everything for the mainframe from installing and customizing the operating system to installing and customizing vendor software to installing, customizing, and managing the databases to RACF administration to Storage Management to VTAM and TCP/IP maintenance to ... you get the picture. We have TWO systems programmers doing all of this.
I think we're overworked. But the plan was that we'd only have to carry this workload for 5 years and then the mainframe would be gone and we'd go back to normal workloads when we get integrated into our 18-man Sun/Solaris SysAdmin pool. We've been doing this for 18 years now ... and management is projecting that we'll only need to do this for another 3 years ...
