“The transilience index reflects the degree of technical difficulty of innovations over time. For the 1894–1980 period, Abernathy et al. [41] construct this index for the American car industry, based on a coding of 631 technical innovations using a 7-point scale (based on how disruptive the innovation is to the production process).”
