Open University behind IT’s development (11)
I believe the answer is:
uninhibited
'open' is the definition.
(thesaurus)
'university behind it's development' is the wordplay.
'university' becomes 'uni' (informal abbreviation).
'development' indicates an anagram.
'behind'+'it'='behindit'
'behindit' anagrammed gives 'nhibited'.
'uni'+'nhibited'='UNINHIBITED'
(Other definitions for uninhibited that I've seen before include "Lacking in restraint" , "Not restrained" .)
