Field studies can add a lot of value to product development with first-hand observation and interview data. But it can become especially effective and enlightening if a cross-functional product team takes part in the process. Why? Field research with a cross-functional team includes much more than just better teamwork.
How does user research usually proceed? The researchers go into the field, talk to the users, observe them, collect data, analyze it and present it to the product team. They make suggestions for iterations on the interface and wait for the dev team to implement them. But its familiarity does not make this process effective. It actually has potential problems on multiple layers.
