Ted,
Please refer to the discussion topic (...LabVIEW>LabVIEW General>Topics...) regarding Programming guidelines. There is a bit of discussion in that thread about source code control and project management.
This is a very difficult subject to learn, especially when applied to LabVIEW coding, as all the information out there is strictly limited to text based programming.
I suspect (I know for a fact...) that there are materials in the works that would pertain to this exact subject. Keep your eyes on the NI website under reference materials that may speak of such subjects.
Good luck
