A customer journey map outlines the step-by-step experience a customer has when trying to solve a problem or achieve a goal. Common pitfalls in creating customer journey maps include the map not reflecting the current state, having too many steps, and containing proposed solutions rather than just documenting the current experience. To avoid these pitfalls, teams should interview customers beforehand to gather real data, set the appropriate level of granularity, and remind the team to focus on the big picture rather than proposed solutions when creating the customer journey map.
