'organisation tested partner lacking experience' is the definition.
I can't judge whether this definition defines the answer.

'organisation tested' is the wordplay.
'organisation' becomes 'un' (UN is an example).
'tested' becomes 'tried' ('try' can be a synonym of 'test').
'un'+'tried'='UNTRIED'

Can you help me to learn more?
