After digesting your various helpful suggestions I have developed the following plan:
1. Create and save a notebook that I will call the Tutorial Master Notebook. This will eventually become the final product, theTutorial.
2. Create a first Working Notebook in which I will develop code to execute an interactive example ("the experiment"). When I am satisfied that the code is working properly, I will copy just the cell containing "the experiment" and insert it into the Tutorial Master Notebook. I will then open another notebook, Working Notebook #2, and develop another experiment and repeat the process of copying and inserting. And so on.
3. At any point in the development of the Tutorial, I may deploy the Tutorial Master Notebook as a CDF and, if it works as planned, save it as Version 1,2 etc until the final version is reached.
There are evidently more elegant programmatic ways of accomplishing what I am after, but since i am a novice in Mathematica my plan is the most easily do-able at the moment. Perhaps it will be useful to others.
