Noun
feature creep (uncountable)
The tendency of a design project or product cycle to accumulate more and more features or details, rather than to be completed and released at a more basic level.
Our sales division promised our client a feature in our software that is currently not feasible for us to implement, which will certainly lead to feature creep.
