We are all drowning in work and automation seems to be our only salvation. But sometimes our best intentions lead to horribly broken systems that need manual intervention or are outright unmaintainable. How does that happen and what can we do to prevent that? In this talk I want to show some mental models and frameworks to create good automation systems that support our teams and reduce the need for manual actions.

As you work, you have a choice:
Will each manual task create artifacts
that allow you to accelerate future work,
or do you squander these opportunities
and accept the status quo?

in the end you need impossibly smart people to
understand your system

CONCLUSIONCONCLUSION
1. Only that should be automated what can be done
manually.
2. What has been automated should always be doable
manually.
3. What happens, even when automated, should not be
hidden from the admin.
