Jesmond Allen introduces himself as the UX Director at cxpartners and discusses how product managers (PMs) and UX designers can best work together. While their roles overlap in understanding users and requirements, UX focuses on design while PMs focus on the product vision and roadmap. For effective collaboration, UX designers should ask questions to fully understand the project brief and deadlines, while PMs should provide clear goals, share existing research, and communicate regularly with stakeholders. The key is open communication between PMs and UX designers.
