The picture shows the development of improving the producer-customer relationship:
(1) a large enterprise with a pre-arranged layout without feedback,
(2) an enterprise with several separate operations,
(3) a network of independent enterprises of a multinational company,
(4) a part of the company specifically adapted to the service,
(5) a one-off enterprise ceases to exist after the provision of the service,
(6) automatic provision of tailor-made services only through the network (Internet of Things).
