I would suggest an alternate labeling for the engineering and manufacturing digital thread. The generalization of digital thread introduces the categorization of thread types, i.e. “engineering thread”. If the attempt is to be discrete in assigning a label to a digital thread then a descriptive label that easily identify the purpose/use of the digital thread should be used. Digital Threads align data/information with sequence(d) events/tasks/objectives.
