Skittles technique's failure sorted out beforehand (6,4)

'skittles technique's' is the definition.
I know nothing about this answer so I cannot judge whether it can be defined by this definition.

'failure sorted out beforehand' is the wordplay.
I cannot really see how this works, but
'failure' could be 'flop' (flop is a kind of failure) and 'flop' is located in the answer.
an anagram of 'sorted' is 'dorset' which is present in the answer.
This accounts for all the letters.
This explanation may well be incorrect...

Can you help me to learn more?
