Abstract : The author has personally modeled designs varying from a Small Scale Integration (SSI) printed circuit board (PCB) up to a modern tank Fire Control System (FCS) of over 20 boxes using over a dozen Testability Figure of Merit (TFOM) tools. These various algorithms used a total of 70 different outputs that were intended to measure the TFOM inherent for a particular design. This paper will first review and categorize all of these TFOM values. Next, will be an attempt to lay the groundwork necessary to figure out if the optimum TFOM should be 'one magic number' or several unique numbers. And finally, if several, what could they be?
