Using the constant comparative method, as introduced by Strauss and Corbin (1990), outside the context of grounded theory, especially in a multiple case study design, is a creative application that can yield rich insights. While the constant comparative method is often associated with grounded theory, its flexibility allows adaptation to various research designs. Here are some additional thoughts and recommendations:

1. Understanding the Constant Comparative Method:

• Ensure a solid understanding of the constant comparative method and its key principles. While it is often linked with grounded theory, its iterative and comparative nature can be applied in different research contexts.

2. Adaptation to Case Study Design:

• Recognize that the constant comparative method can be adapted to fit case study designs. In multiple case studies, you can use it to identify patterns, commonalities, and variations across cases.

3. Literature Review:

• Conduct a literature review to identify studies or articles where researchers have applied the constant comparative method in non-grounded theory contexts or within case study designs. Look for examples and insights on best practices.

4. Methodological Articles:

• Explore methodological articles and books that discuss the constant comparative method beyond grounded theory. Researchers may provide guidance on its application in different qualitative research frameworks.

5. Reflexivity and Transparency:

• Emphasize reflexivity in your research process. Clearly articulate how and why you are using the constant comparative method in your multiple case study design. Transparency in your methodology is crucial for ensuring the rigor of your research.

6. Case Selection:

• Thoughtfully select your cases. Consider the diversity and relevance of the cases to your research question. The constant comparative method can help you identify patterns both within and across cases.

7. Data Collection Strategies:

• Plan your data collection strategies to facilitate constant comparison. This may involve collecting data from various sources, such as interviews, documents, or observations, and comparing them iteratively.

8. Coding and Analysis:

• Apply open coding, axial coding, and selective coding – key components of the constant comparative method – to analyze your data. Iteratively compare data within and across cases to identify themes, patterns, and relationships.

9. Triangulation:

• Consider using triangulation methods to enhance the validity of your findings. This could involve comparing findings across different data sources or involving multiple researchers in the coding and analysis process.

10. Flexibility in Analysis:

• Be open to adjusting your analysis approach based on emerging findings. The constant comparative method allows for flexibility and responsiveness to the data.

11. Reporting:

• Clearly report your methodology in your research documentation. Explain how you adapted the constant comparative method for your case study design, and discuss the implications of your approach.

12. Collaborate and Seek Feedback:

• Collaborate with peers or seek feedback from experienced qualitative researchers. Their insights can be invaluable in refining your approach and ensuring the robustness of your analysis.
