Two essential processes in Grounded Theory are Open Coding and Memoing. Open Coding is the initial phase where researchers break down the data into discrete parts, closely examining and comparing these parts to identify themes and patterns. Memoing involves writing reflective notes about the data and codes, helping researchers to keep track of their thoughts and insights throughout the research process.

Following Open Coding, Axial Coding and Selective Coding are used to further refine and integrate the emerging theories. Axial Coding involves reassembling the data in new ways by establishing connections between categories. This stage helps in understanding the relationships and hierarchies within the data. Selective Coding is the process of focusing on the core category that forms the central phenomenon of the study, integrating and refining the theory around this core.

Theoretical Saturation is a crucial concept in Grounded Theory. It refers to the point where no new data is being found that adds to the theory. At this stage, data collection can stop as the categories are well-developed and validated.

Grounded Theory falls under the broader umbrella of Qualitative Data Analysis (QDA) and Qualitative Research. These methodologies focus on understanding phenomena from a subjective, human-centered perspective. Grounded Theory's systematic approach to theory generation makes it a robust tool within the qualitative research paradigm.

In-depth Interviews and Narrative Research are common data collection methods used in Grounded Theory. In-depth interviews allow for a deep exploration of participants' experiences and perspectives, while Narrative Research focuses on the stories people tell about their lives and experiences. These methods provide rich data that are essential for developing grounded theories.
