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.
