13.2 You will generate three broad types of data that you will need to retain and file as the result of undertaking qualitative research. The first of these may be referred to as raw data files. These are your original notes and audio-recordings made during the conduct of interviews or observations, or from consulting documentation. In addition, you will also retain transcripts and written-up notes of interviews and observations, although these may also be contained in a computer file. The second of these is analytical files containing your categorised data. Alternatively, this may contain your summary or your narrative. These may of course also be contained in a computer file. The third of these may be referred to as a supporting file, or indeed it may be different files, containing working papers, self-memos, interim reports and so forth. Again, these may also be contained in a computer file. You are well advised to keep all of this until the end of your research project. Eventually you will create a fourth file – containing your finished work!
