"RESEARCH AND DEVELOPMENT" IS VITAL FOR A GROWING BUSINESS!
When I ask Spanish people how to say "I+D" in English often they are not sure.
High level students might know the answer but most of the time there is silence. The word "development" is probably a bit easier to know but the translation of "investigación" is often difficult to translate for Spanish people.
So remember: "Investigación y desarrollo" (I+D) = "Research and Development" (R+D).
Hope that helps.
