“The term saturation is used ubiquitously in reports of qualitative research. The term is often used, however, as a throw-away line, sans definition, rationale, or explanation of the process. Consequently, there remains a question about what is meant when saturation is used.The concept of saturation originated in grounded theory. Achieving theoretical saturation is one of the tenets of grounded theory. Over time, this specific and singular term has migrated to a general term that reflects various types of saturation such as code, data, theme, and meaning saturation. There is a lack of clarity among saturation types and a lack of transparency in reporting what is meant by saturation and how it was achieved. There is also a question about the relevance of saturation to qualitative methodologies outside grounded theory.”
