Lived experience stands in contrast to observational experience.
I as an outsider may observe friction in a developer--customer meeting. Ask the developer, and they may reveal that they found the arguments during the meeting highly valuable and productive. A lot of case studies and experiments in productivity improvement are observational. You do something and then you look at the results, rather than how the lives of the people involved changed.
When an outsider looks at a situation, they often see something very different to what the people in it did. That's the difference between lived ("insider") and observed ("outsider").
(Of course, strictly speaking, you don't get lived experience from interviewing people. People being interviewed tell you, to some extent, what they think you want to hear at that time. To really get closer to lived experience the researcher has to embed with the group being studied and work with them for some time.)
