“Channels are completely fluid to the context of our needs. We can define them broadly: digital channel versus phone channel. Or we can zoom in and define them more narrowly: mobile channel versus desktop web channel. Or more narrowly still: native app versus mobile web. The purpose of defining channels largely depends on the context in which they are being discussed – at what detail do you need to define a particular channel to support the experience? You’ll typically define them more broadly at the organizational level, and then more narrowly as you move down to the strategic and then tactical level.”
