"Qualitative research is often opposed to quantitative research. But numbers can play an important role in illustrating analyses in qualitative research. Their persuasive, concrete nature can help ensure the success of a workplace intervention, especially in the North American context, where numbers are treated very seriously. We describe a method of work analysis and transformation developed at the Conservatoire national des arts et métiers in Paris, where the meaning of the numbers used is critical. We think that the numbers used in work analysis have a different meaning from that in a "pure" quantitative study, where they are submitted to statistical procedures for hypothesis testing. Using examples from recent studies carried out in Québec and Canada in collaboration with unions or joint health and safety committees, we show that counting can be part of qualitative analysis, enrich our portrait of organizational and physical aspects of the work process, and help indicate pathways for workplace improvement."
