The documents we write at work should be, primarily, useful.

That is, these documents will usually contain vital information that users need to perhaps make a decision, or follow a process, or complete some other action.

Readers need information and knowledge they can act on, and they need to gain that knowledge with some ease.

Readers should be glad they read your document because it helped them in some way.

Here’s 3 dimensions to help evaluate documents:

1. A document should be useful.
   That is, it provides content readers can act on.
2. A document should also be usable
   That is, readers can quickly and easily find the information they need and understand it.
3. A document should be desirable
   Attractive to look at and attractive and pleasant to read with valuable content.
