This question already has an answer here:
I am writing a business plan for management, in which I wish to differentiate the options between that something is a must (mandatory) and other thing 'nice-to-have'.
The concatenated word 'nice-to-have' sounds less formal for business proposals, but I am not able to find a proper 'big' word. 'Optional' or 'alternative' might work, but it lacks the meaning that the option is perceived to 'be nice'...
Well, what I am asking is to seek a formal expression, and it doesn't have to be a noun. The context of the business proposal is like below:
After investigation, we believe that (1) The acquisition of XXX is mandatory as it's concerned with XXXX; (2) Taking ownership of XXX is always a nice-to-have, but considering current human resource, we may not take immediate action.
