The memo of your understanding of GT is a part of your GT study

Silence and Voice is Jeffrey Keefer's blog. The entry "Musing on Grounded Theory" and the discussions about grounded theory show how a new researcher starts to learn grounded theory approach, new researchers' confusion between different GT works, and what a researcher's grounded philosophical thinking is.

A necessary way is to write down your ideas/understanding about grounded theory approach and its use over the process of your grounded theory research study. It is a part of your research memo and it notes your views/ideas developing.
