Taking lessons learned from other similar industries/sectors are invaluable.

Using a few words and symbols to communicate a lot isn’t a novel concept; street signs have been following the same basic principles as UX writers for decades. Calls to action, non-intrusive instructions, and universally-understood symbols are as essential in road signs as they are in software development. The discipline of optimizing road signage is almost a century old and still going strong today so there is much UX writers can learn from these helpful sheets of metal.
