The build trap is when organizations become stuck measuring their success by outputs rather than outcomes.
I guess this relates to a point made in Accelerate about measurement models. It’s preferable to use a capabilities model of measurement to continuously know if your product is where you want it to be, rather than a maturity model that tells you if your product has reached a certain state.
Product management is the domain of recognizing and investigating the known unknowns and of reducing the universe around unknown unknowns.
Observability is also about unknown unknowns and deep down it all goes back to testing. But hey, I might be biased here.
