Both "improve" and "improve upon" can be used, but they have slightly different connotations. "Improve" typically means to make something better in a general sense, while "improve upon" suggests building on an existing idea or standard to make it better. Use "improve" for straightforward enhancements and "improve upon" when referring to enhancements that build on prior work or concepts.
