If you're asking which certs give a high probability that the certificate holder can do the job, that's one thing. If you're asking which certs will get you on the short list for a hiring interview, that's another.
PMP may actually appear on both lists. I know that it appears on a lot of postings for Project Managers. And project mgmt isn't just managing Gantt charts. It's a whole sub-discipline under Industrial Engineering.
The big certs right now appear to be for security pros.
