Excellent advice here:
[N]ext time you’re designing a new interface paradigm or chatting with an engineer, ask yourself about the risks involved in the known versus the unknown with the following questions.
- Does the new design use intuitive patterns that prioritize consistency?
- Are you in any way disregarding accessibility practices in favor of a feature or a visual direction?
- How tech-savvy are your users and can the newly-introduced experience be easily adopted by current and future, more-diverse audiences?
- Can and will your design decisions be validated through properly conducted user research and user testing?
Being mindful of these practices will help you guide decisions and ensure you don’t change things just because you can.
