Phased in changes in clergyman's office (8)

I believe the answer is:

deanship

'clergyman's office' is the definition.
(the office or responsibilities of a dean)

'phased in changes' is the wordplay.
'changes' is an anagram indicator.
'phased'+'in'='phasedin'
'phasedin' with letters rearranged gives 'DEANSHIP'.

'in' acts as a link.

(Another definition for deanship that I've seen is " University office - phased in (anag)".)

I've seen this clue in The Times.
