User experience starts at the bottom

The whole chain of user experience starts with the people creating the content for the end user.

If their experience is sub-optimal, the content, and the product they create for the end user will suffer.

It is therefore important to also consider strongly the UX for the people who will be creating, editing and managing content and production.

And for the designers and developers creating those tools in the first place.
