The book is exactly the opposite of this. The Principles chapter alone talk about many things that involve actually dealing with numbers (SLO, measuring complexity, etc).
- kortilla 2y ago“It has numbers attached” does not mean something is backed by data. Unless they are testing correlations between these target metrics and business success or some other external cost metric, it’s still “just feels”. I’ve seen internal crusades against cyclomatic complexity that resulted in massive engineering waste to reduce and reliability saw no improvement.
- kubb 2y agoYeah, but to be fair I don’t think Googlers can tell the difference between a decision backed by data, and a random ass measurement.
