Pitfall 1: Not enabling self-
service

@samnewman
Teams empowered to make
decisions and get thing done

@samnewman
AWS’s killer feature is
supporting self service

@samnewman
Top Tip: Trust your people

@samnewman

@samnewman
“We’re like a utility - we just
sell electricity”

@samnewman
Having cool tools isn’t
enough - you have to help
people use them

@samnewman
Pitfall 2: Not helping people
use the tools well

@samnewman
The job of the platform team
should not be just about
building a platform…

@samnewman
…it should be about
enablement

@samnewman
Does your platform team do
outreach? Training? Spend
time embedded with other
teams?

@samnewman
If not, they can become just
another silo

@samnewman
Top Tip: Treat your microservice
platform like a product

@samnewman

@samnewman
Top Tip: It’s OK to provide a
curated experience

@samnewman
Governance

@samnewman
Deciding how things should
be done, and making sure
they are done

@samnewman
Pitfall 3: Trying to implement
governance through tooling

@samnewman
“You must use the platform!”

@samnewman
Forcing people to use your
platform isn’t about enablement,
it’s about control

@samnewman
Shadow IT

@samnewman
If you make it hard for people
to do their jobs, people will
likely either bypass your
controls, or leave

@samnewman
Be clear about what needs to
be done, and why

@samnewman
Then make it as easy as possible
to do the right thing

@samnewman
Top Tip: Provide a paved road

@samnewman

@samnewman
Top Tip: Make the platform
optional

@samnewman
This will ensure that the
platorm owners are focused
on ease of use

@samnewman
It also allows for alternative
solutions where warranted

@samnewman
A paved road - not a railroad
track!
