The linear-graph notation is useful because it provides an abstraction which has the same form for the two entities we are considering: the design organization and the system it designs. This can be illustrated by replacing the following words. Replace "system" by "committee." Replace "subsystem" by "subcommittee." Replace "interface" by "coordinator."

“Organiza4ons  which  design  systems  […]  are  constrained  to  produce  designs  which  are  copies  of  the  communica4on  structures  of  these  organiza4ons.”  

Conway‘s  Law  

So:ware  Is  The  New  Hardware  

Disruptive innovations are not breakthrough technologies that make good products better;

rather they are innovations that transform sectors to make products affordable and

convenient, thereby making them available to a much larger population.

A  disrup4ve  innova4on  is  an   innova4on  that  helps  create  a  new  market  and  value  network,  and  eventually  disrupts  an  exis4ng  market  and  value  network  (over  a  few  years  or  decades),  displacing  an  earlier  technology.    Sustaining   innova4ons   are   typically   innova4ons   in   technology,   whereas  disrup4ve  innova4ons  change  en4re  markets.
