12. Killer Features
≒ At first we ventured to exclude some
features, but many users wanted to have
them remain.
≒ We asked users to explain the reason for
their requests, and the potential issues if
these features were removed.
≒ We came up with new, alternative features
that don't con鍖ict with our services'
concepts.
≒ As a result, these became killer features that
improved the value of our services
