User experience design involves creating and coordinating all digital and physical elements that affect a user's experience with a company to influence perceptions and behaviors. Starting a new project requires understanding the company culture, types of websites, and people involved. Well-written proposals provide stability and protection by outlining the project overview, approach, deliverables, costs, and payment schedule. Defining user groups involves researching attributes and prioritizing which groups to focus on. Prototyping and testing designs with users helps improve the design by synthesizing feedback. After launch, log file data and customer feedback are analyzed to identify issues and plan further testing.
