Like all sayings, there is context for moving fast and breaking things.
The saying means that when creating something new for profit, don't worry too much about trying to figure out all the details beforehand and figure it out as you go. This will inevitably cause things to break, but being able to quickly fix that when it happens is the same skills needed to create new features as you go.
The saying does not work with large and complex established systems where breaking things wreak havoc.
It also feels like they chase the βbreak thingsβ part as if not breaking stuff is a bad thing, and like we should be proud of them for releasing broken and poorly tested updates.
Move fast, break things, fix the broken things, push update/product whatever. They keep forgetting the third step.
Like the startups that 'disrupt' the established system by ignoring laws and breaking the parts that worked and selling it like an improvement.
'Ride sharing' (unregulated cabs) was only cheaper because of investor funding allowing them to undercut on pricing, abusing the concept of contract workers, and the companies ignoring laws. That isn't 'disruptive' by being innovative, that is cheating the system.
I think there is another aspect that is important: limit the blast radius. Shit inevitably happens when you create something new and complex, and when it does, youβd rather minimise the impact where possible.
Management said that writing tests takes too much time and eats into the time that could be used to write features for the app, so they decided that we're not writing tests. They were always green anyhow
Always remember, the silicon valley ethos of "break things" wasn't about their applications, it was about breaking industry, society, laws and your ability to oversee or regulate them.
