Move fast and keep your code quality
None
This talk is not about faster development
This talk is about quality
Productivity is a by-product of Quality
⚠ FAIR WARNING ⚠
Not for lone wolfs !

Productivity is a by-product of Quality

Option C

“Look at all these shitty lines of code I just
wrote!” No one, ever.
We're proud about the quality of our work Not the
quantity
Less quality More production bugs
More bugs less productivity
1 1 Integrating Software Assurance into the Software Development Life
Cycle (SDLC)
100x
Spaghetti code More time per new feature
More time per feature less productivity
Quality means fewer bugs
Quality means faster development per feature
Who's in charge?
Quality is not QA's responsibility
Quality is a company wide effort

Chapter two The Project
Flat hierarchy?
Flat hierarchy is a lie
This is informal leadership 3 3 Cut the bullshit: organizations
with no hierarchy don’t exist
Make it explicit
What does a manager look like?
More structure Distributed responsibilities
What is quality?
Good definition of requirements 4 4 Peopleware: Productive Projects and
Teams by Tom DeMarco
Requirements are met Good Quality
Short iterations
Context switching
“When interrupted, it takes an average of 23 mins to
get back to the task. 5 5 Worker, Interrupted: The Cost of Task Switching
Work like you're remote
Rely on async tools
Chapter three The Team
Teams are more important than projects
It's hard to form a good team If it works,
keep doing it!
Form projects around teams not the other way around
Creating good teams
Keep'em small
Sharing knowledge
Study groups
Standards
Pull Requests and Code Reviews

Quality first
There's no silver bullet
