Memos are personal instruments that a qualitative researcher generally uses for themself or in team research, whereby ideas are written down when they arise during the analytical process. Memos enhance the analytical depth of qualitative research by allowing researchers to record insights, reflect on data, and document the analysis process. NVivo contains two memoing tools discussed in this chapter: memos and annotations. The creation of memos and annotations is demonstrated, and the connection of memos to data is shown with the memo link.
