I don't know if this is what you are looking for, but here's my take on the issue:
It all has to do with what the person is doing. If a person is doing desktop support and PC repair, then the A+ and MCSE could be warranted together, if the person is a c++ programmer, then it makes little sense.
What I see so often on this column is that someone will get their CCNA or MCSE and then expect for the pot of gold to drop out of the sky - the truth is that these skills are only a small part of the overall skills that a well rounded administrator needs to have:
A good well rounded administrator needs
#1 Great Communication and People Skills!
#2 Great Problem Solving Skills
#3 Leadership Skills
#4 Project Leadership Skills
#5 Operating System Skills
NT/2000 (MCSE goes here)
UNIX/LINUX
VMS, AS/400, etc.
#6 Network skills on various network hardware
Here's where your CCNA, CCDA, CCNP, CCDA, CCIE
come to play - your N+ goes here
#7 Database Skills - Oracle, Sybase, SQL Server
#8 Data Storage Skills - storage cabinets, storage management
#9 Security Skills
#10 Skills with applications and development projects
#11 (not unimportant at all) - Customer Service Skills
Personally, I really think ittakes a person with the right temperment to do this job, and do it well. It really takes someone who is VERY service oriented, and who is not easily frustrated.
So, what in the world does this have to do with ROI - well, the truth is that you usually never know if it helped you unless you Didn't do it.
This is the truth. Just ask the guy who is stuck on the helpdesk because they don't have a degree or a desired certification, and they can't get off the helpdesk into a better position.The
real ROI is hidden and it's something you'll never really know.
