@danielbryantuk

6. Gray’s
Model
of
Companies
• Divided
Companies
– Tradi7onal
‘enterprise’
(machine
analogy)
– Command
and
control,
specialised,
division
of
labour
– Predictable
in
stable
environments
– Classical
SOA?
• Connected
Companies
– Hipsters
and
unicorns
(biological
analogy)
– Autonomous,
fractal,
service-­‐focused
– Adap7ve
in
uncertain
environments
– Microservices?

7. Connected
Companies
• Startups
– Searching
for
a
business
model
• Established
companies
– Amazon
– Spo7fy
– Neblix
– Etsy
