Lloyd has been researching what makes a user-focused organization a successful one. During this research, Lloyd has come to realize that everyone plays a part in optimizing the user experience on an ongoing basis. What is the designer's part in optimizing the user experience on an ongoing basis?

The designer's role in ongoing UX optimization is to collaborate with developers to create testable variations of designs. This ensures that design hypotheses can be validated through A/B tests or other experimentation methods. While other roles might support testing (like management enabling budgets) or implement changes (developers), the designer's specific contribution to ongoing optimization is in crafting the testable design options. Building test environments and implementing changes are developer responsibilities. Implementing tracking and sharing data are typically the roles of analysts or product managers.
