QCA is essentially a quantitative technique that does not examine the content of the data. If you have a rich qualitative data set, you could do a QCA first, and then do a further thematic analysis to help understand the results of the QCA.
There are different kinds of thematic analysis - would help to have some more details of your project. Looking at QCA I have some doubts about the possibility of "formalizing the logic of qualitative analysis" http://www.socsci.uci.edu/~cragin/fsQCA/index.shtml
as I'm not sure this could be done. My initial feeling is you would need to do some other type of thematic analysis as well to avoid missing something essential. It all depends what you're trying to achieve.
dear A. S. CohenMiller , the study is related to make comparison between the perceived performance of employees of two banks reported by Bank managers. the views of the banks managers were collected through close end interview @ A. S. CohenMiller
This question is polysemic at this point. It lacks indication as to what you wish to compare. Just to be clear, thematic analysis (TA), like many qualitative research methods, is based on the "constant comparative method". Thus, comparison is an inherent part of the analysis.
That said, if by "comparison" you mean comparing two populations/groups/phenomena, then I would advise against it in a qualitative research design. Simply because you cannot generalize from the analysis to the populations/groups/phenomena.
Rather, you can do two (or more) SEPARATE qualitative studies, and then either discuss differences between the findings (acknowledging that you don't really know whether the findings are representatives of the populations/groups/phenomena) under scrutiny, or otherwise argue that comparing them QUANTITATIVELY would be worth pursuing based in the OSTENSIBLE differences found in the preliminary/precursing qualitative analyses.
The comparative method can be used as a complementary method in analyzing causal conditions along with thematic analysis. For example, you can refer to my article.
