Chekhov's Gun

This post deals more with the technicalities of writing, and I would consider it to describe a strategy for analyzing descriptions in the story, and truly looking at whether or not you are being superfluous in description.

Chekhov's Gun is essentially the principle that the details and memorable elements to the story must be purposeful, or have a role later in the story. In his words, "Remove everything that has no relevance to the story. If you say in the first chapter that there is a rifle hanging on the wall, in the second or third chapter it absolutely must go off. If it's not going to be fired, it shouldn't be hanging there."

The reason I think this is worth talking about, and a genuinely good rule to follow is it enhances your story in that it is more engaging.

If every detail or element to the story ultimately has a purpose, your readers will forever be guessing at how everything will tie together, and it will cause them to scour the book's details and mentions for clues at what will happen next.

This is huge to keep people not just flipping from one page to the next, but genuinely captured by the story.

In practice, I think this is also a really fantastic way to cut down your word count in editing should you find yourself with one that's too large. It will force you to weed out that which you don't need, and leave you a story that is tight and interactive, and would likely help to clean up some of the writing or even bits of the plot.

Now, this isn't to say you shouldn't describe anything unless every word in the description has a meaning later, but it is a good way to look at symbols or objects and what role they could play. Again, describing someone's features, or building the word is vital to the story, so you can't take it out solely on the principle it's not coming back as part of the plot, but it is a cool device to use with objects or concepts that you know will be part of your plot later in the novel.
