George,
Project organization is strictly up to you. As long as you have the VIs that you are going to be using for executables in the project, what you have included in them is just for organizational purposes. That being said I would include everything that deals with that function. As long as the build specifications have good names, having the data processing VIs in the project should make everything easier to read. I might suggest having the data production VIs under one folder and the data processing VIs under another folder. For me I would like to see how the data is being produced and analyzed. Feel free to report with any thoughts.
