There are many ways to research customer journeys, but they can be broadly categorized into two types: qualitative and quantitative. Qualitative methods involve talking to or observing your customers directly, such as interviews, surveys, focus groups, or user testing. Quantitative methods involve analyzing data from your systems, platforms, or tools, such as analytics, CRM, or feedback. Depending on your goals and scope, you may want to use a combination of both types of methods to get a comprehensive and accurate picture of your customer journeys.
