Digital Twin technology existed long before this term came into common use.  Over time, existing technology has advanced, new applications and research initiatives have surfaced, and related technologies have been developed.  This lack of centralized “ownership” of the term or technology has led to the proliferation of differing definitions of “digital twin.”
     Some definitions focus on a specific application or technology – that developed by those offering the definition – presumably to coopt the term for their own purposes.  Arguably, the most useful definition, however, is the broadest – one that encompasses the range of relevant technologies and applications, capturing their corresponding value to the field.  To this end, I offer the following definition of digital twin:
     An electronic representation of a physical entity – product, machine, process, system, or facility – that aids understanding of the entity’s design, operation, capabilities, or condition.

     Reviewing past installments of “The Third Degree” in preparation for the update post “Hindsight is 20/20; Foresight is 2020,” I realized that there had been a significant oversight.  This post is aimed at correcting that oversight and filling the void I’m sure we have all felt.
     In “Of Delegating and Dumping,” a compare-and-contrast exploration of the two managerial styles, I referenced “The Dumper’s Creed,” but had not presented it.  Until now!

     The advent of a new year inspires a great deal of reflection and anticipation.  Many of us will evaluate our personal and professional progress over the past 12 months and set new goals for the upcoming year.  The same is true for “The Third Degree;” this installment will look back at some posts to provide additional resources related to the topics discussed.  It will also look ahead to preview topics to be covered in future posts.
