Company boss integrates R&D as an article of faith (5)
I believe the answer is:
credo
'faith' is the definition.
(I've seen this before)
'company boss integrates rd as an article of' is the wordplay.
I cannot really understand how this works, but
'boss' could be 'ed' (short for editor - newspaper boss) and 'ed' is located in the answer.
'of' could be 'o' and 'o' is present in the answer.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for credo that I've seen before include "Set of beliefs about leftist circle" , "Words of believer" , "Dogma" , "Guiding beliefs" , "Decor (anag.)" .)
