Finally case study is appropriate method to research in any
area in which few previous studies have been carried out and when boundaries between phenomenon and context are not clearly evident .
Furthermore other academic authors argue that single case study is appropriate, if it proves to be a revelatory case, or it is critical or finally extreme or unique .
This qualitative approach is, thus, relevant to explore emerging lines of enquiry in order to build theories.
The research method can involve several instruments as evidences from fieldwork, archival records, verbal reports, observations and above all unstructured or semi-structured interviews.
For this work, we propose an illustrative and exploratory single case study that has the aim to illustrate new innovative practices, which can be considered particularly advanced.
Besides this method allows the researchers to answer the
research question in a single firm as preliminary and pilot investigation .
