It is Sunday, cannot imagine someone would be working today (of course not in service sector).
I called up my friend,...turned out she has on-call duty today, anyway, .....she told me that it is such a hectic day for her as a couple of million dollar was lost, after only 8 hours of her employer's computer system went down since the business operation really relied on the system.
The root cause, was due to the server upgrade project which was planned months ahead, but when it didn't work out as it should be.
All the technicians spent all the efforts trying to fix the problems because they had no clue of what to do if the upgrade hadn't gone as planned. They only knew how to go forward,..... but somehow forgot to give any attention on how to step backward safely to the origin without falling.
As previously mentioned, RDM has not been my company.
so, I only know how to go forward when deciding on my education.
I don't have any backup plan of if I flunk this, what would be the next step besides tumbling down the hill, into a pool of quicksand and start sinking slowly.
What is more robust? planning to make a firm move forward to minimise failure or planning for possible worst case?
or maybe the combination of both ;D
