System errors

Do computer systems make mistakes?
Yes, ALL THE TIME!

Just this week I had to spend many hours of my time calling and chasing up to fix errors made by computers. For example:

– My credit card is set to be paid automatically but it didn’t, leaving me with extra fees and marring my credit record

– A product I paid for online but the order somehow wasn’t “captured” by the system… now have to go beg for it or get my money back

– Order shipments going in the wrong place

– Airline miles not being recorded after flights

And the list goes on…

The problem is, in each case I have to drop my work and go chasing after these things which originally should have happened correctly. I wonder what is the total loss of porductvity in the world because of such things!

In this day and age we trust computers with nearly everything.

I suppose computer errors are mostly due to human errors of the people handling these systems?
