I carry out business model (5)

I believe the answer is:

ideal

I'm a little stuck... Click here to teach me more about this clue!

'business model' is the definition.
'ideal' can be an answer for 'model' (ideal is a kind of model). I am unsure of the 'business' bit.

'i carry out' is the wordplay.
'carry out' becomes 'deal' ('deal' can be a synonym of 'carry out').
'i'+'deal'='IDEAL'

Can you help me to learn more?

(Other definitions for ideal that I've seen before include "Pattern" , "Standard to aim for" , "example" , "In her dreams" , "fine" .)

I've seen this clue in The Telegraph.
