A succinct way I’ve framed the split is that a front-of-the-front-end developer determines the look and feel of a button, while a back-of-the-front-end developer determines what happens when that button is clicked.
Doing it right requires a different pace of working and a much broader thought process than “ok, let’s get this thing out the door.” Which is super tough because most workplaces place a huge emphasis on getting things out the door, and fast. Little agile tickets that are expected to be completed in micro sprints to me seem to be antithetical to doing it right.
I’m concerned with how I witness the work of user experience practitioners getting treated: like it’s just a set of motions toward a product’s all-important implementation, and one that we try to compress, due to its ostensible superfluity. Once the implementation is finished, the UX work appears to usually get discarded.
I submit that the materials that form the precursors to a product’s implementation have considerable value on their own.
My vision is that I will be able to ask a question as mundane as one about the wording of a single button, and trace the answer all the way back to the overarching business strategy to see that it makes sense.
It isn’t a site, or a service, or even an identifiable product at all, but rather a system for creating a skin around and connective tissue between things like:
Demographic studies
Contextual inquiries
Stakeholder and user interviews
Surveys
The business ecosystem
Personas
Scenarios
Sketches, storyboards, wireframes
Mockups, models and prototypes
Email and IM conversations
Meeting notes
Content inventories and audits
Concept schemes, taxonomies, thesauri
A UI style guide
A branding and visual identity guide
A voice and tone guide
A code style guide
...etc
The individual elements of such a corpus represent the work of half a dozen specialist sub-disciplines, and are useful for realizing a product’s implementation. But if you hook them all up together, they merge to become a strategic artifact that transcends products and operates as a critical control surface for the business. This is because what such an artifact represents is a coral reef of deeply-considered and hard-fought decisions, and a story of the process that yielded them.
