There has been an explosion of interest in atomizing research, where researchers stop writing reports and instead tag individual insights in a database. The theory is that this will unlock your insights, making them findable and reusable. But does it work, and should you be doing the same? At Microsoft we tried it: Five years, 40,000 insights, 20+ research teams, and 17,000 unique users. So what have we learnt? We learnt that a structured insight library can be worth the effort. But we also learnt that atomizing insight can be taken too far. We learnt that context is critical. We learnt that short term efficiency is king, and that the required culture change is hard. And through this journey we’ve begun to discover how to blend atomized insight with your traditional research process.
