6. PERFORMANCE COMPETENCE Technology Science PASTFUTURE IDEATION Social Sphere PROTOTYPES Supervening Social Necessity

7. Prototypes Rejected because there is no supervening necessity (Ronald’s telegraph) Accepted because an early appearance of a supervening necessity has made it acceptable (Hollerith calculator) Parallel – already in existence solving another technological problem (Hertz radio) Partial – designed to solve a problem but do not (Bell early telephone)

8. Supervening Social Necessity 1.Those occasioned by the consequences of other technological innovation 1.Railway transformed the telegraph into a diffused technology 2.Radio and Iron Clad battleship 2.Concentration of social forces working directly on the innovation 1.Modern business game rise to telephony 3.Commercial interests 1.Super 8mm film, CDs, Polaroid, etc.
