There is communication that solves problems and communication that creates problems.
Choosing the right channel may seem like a small detail, but it completely changes the experience for the message recipient.
This applies to honking at the front door, to a five-minute audio message when a single sentence would have sufficed, to an inconvenient phone call, or to a sensitive matter resolved via WhatsApp.
The message may be right. But the medium also needs to be right.
Efficiency isn't just about getting a quick response. It's about getting what you need with as little hassle as possible.
