Qualitative data but quantitative outcome; what type of research methodology is this?
Well, according to Alan Bryman in his research article Integrating quantitative and qualitative research: how is it done?, this is a theme that is still open to debate. He uses these 5 questions in separating qualitative, quantitative and mixed-methods approaches:


  
  Are the quantitative and qualitative data collected simultaneously or sequentially? (Morgan, 1998; Morse, 1991).
  Which has priority – the quantitative or the qualitative data? (Morgan, 1998; Morse, 1991).
  What is the function of the integration – for example, triangulation, explanation, or exploration? (Creswell, 2003; Creswell
  et al., 2003; Greene et al., 1989).
  At what stage(s) in the research process does multi-strategy research occur? (Tashakkori and Teddlie, 1998). It may be at stages of
  research question formulation, data collection, data analysis, or data
  interpret- ation.
  Is there more than one data strand? (Tashakkori and Teddlie, 2003). With a multi-strand study, there is more than one research method and
  hence source of data. With a mono-strand study, there is one research
  method and hence one source of data. However, whether a mono-strand
  study can genuinely be regarded as a form of mixing methods is
  debatable.
  


In regards to your question, I would say that if by "criteria" you mean forming hypotheses that you later test with quantitative methods, that would clearly be a mixed-methods approach. If not, you are probably more in a grey area.
