TABLE OF CONTENTS A supporting function is a function that must be performed when and if a primary path function cannot be performed without this function being performed at the same time or some time prior to the primary path function. For example, a spring that has stored energy within it cannot release that energy if the energy is not stored in the spring to start with. These functions are sometimes identified during Step 8 by placing a caret (^) symbol in front of a function within a function cluster. However, supporting functions usually are identified by inserting each primary path function into the following question:
When/if this function is performed, what other functions must be performed?
If you are unable to think of an answer when you insert each primary path function where "this function" appears in the question, see if any of your developed clusters include a primary path function. If they do, insert just the functions down to and including the supporting functions until you learn how to perform Step 9. Always copy and paste your developed diagram at the end of your file before you begin to add supporting functions. When supporting functions are added during this step, make sure you place a "9" near the left margin of the appropriate function to indicate its inclusion during Step 9. Make sure you consider other functions which have not been named or identified yet. In...
