HABITABILITY
“Habitability is the characteristic of source code that enables
programmers coming to the code later in its life to understand
its construction and intentions and to change it comfortably
and con
fi
dently.”
- Richard Gabriel

@samnewman
We have a responsibility to create working
environments that make our colleagues lives
easier

It’s ok, I’ve got a platform!

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

@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
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
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!

@samnewman
PITFALLS - IN SUMMARY
Not enabling self-service

It all starts with trusting
your people
