A methodology for deriving quick insights during user research and delivering them as they’re learned to stakeholders, cutting down on the data analysis typically saved for the end of the research stage.
Here's an analogy.
Progressive synthesis is like a reporter that’s live on the scene. Instead of rolling up a story, they’re giving you the updates and insights as they learn them.
Why does it matter?
In order to do research quickly, we don’t always have the ideal amount of time we would like. Progressive synthesis allows us to understand or validate hypotheses quickly, so as not to delay a process.
How does it apply?
Progressive synthesis is a fast way to learn about users or validate an idea. You update your learnings as you conduct more research and learn new information.
