UI and UX designers play closely related yet separate roles in development, be they for a product, a service, an application, a website, etc., and the two terms are often confused, sometimes even used interchangeably.
Describe the difference between UI and UX and the specific roles of UI and UX designers, taking into account how their jobs are similar and how they are different. How would their respective job descriptions vary? (Be specific and give examples.) Could (should) one person take on both roles? (Again, explain in detail and give specific examples.) Explain the relationship between UI/UX design and company success, both in terms of customer satisfaction and potential profitability.
