Managing organisation using basic computer software? (9,6)
I believe the answer is:
operating system
'computer software?' is the definition.
'managing organisation using basic' is the wordplay.
I cannot quite see how this works, but
'organisation' could be 'ratingsystem' (rating system is a kind of organization) and 'ratingsystem' is present in the answer.
The remaining letters 'ope' is a valid word which might be clued in a way I don't see.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for operating system that I've seen before include "Essential computer facility" , "Essential software" , "Software providing a computer's basic functions" , "MO?" , "surgical procedure?" .)
