Tip

Write out the full name when you want to introduce a term (with the acronym in brackets). Use only the acronym after this. Example:

Companies don’t usually talk about FOMO (Fear Of Missing Out). Instead, they use phrases such as “shiny object syndrome” and “market expectations.” Google is a great example of how FOMO can creep in.

FOMO Is Disastrous for Company Strategies by Ruben Ugarte

If you are only going to use the acronym once, maybe don't use it at all and rely on the whole expression instead.
