Prolonged engagement is a means to grasp the point of the research setting

Prolonged engagement is a means to grasp the point of the research setting, understanding the context, its features and details, thereby minimizing distortions; it gets materialized with credibility that, in its turn, is gained diachronically. However, my study is based on a series of interviews, leaving smaller room for this technique to unleash its strength.
Despite having worked for Equinor for more than 10 years and engaged in the business environment in which cooperation between Azeris and Norwegians was clearly visible for observation at different angles, I have not been involved personally in all areas – and levels – of cooperation in my company. On the other side, my acquaintance with some Equinor staff members, who had built up long-lasting working relationship with Socar in the framework of joint projects, was my forte. Those people also knew me well, for they followed egalitarianism, an integral part of the Norwegian culture. Equinor’s corporate culture was another advantage for it gave me unimpeded access to contact C-suite level management and invite them to being interviewed face to face or by means of videotelephony.
At the same time, if one sample departs from the literal meaning of prolonged engagement and concentrates on its main aim and idea, to provide extensiveness of the research, there would be enough evidence to argue that this aim has been reached. Interviews allowed me to cover a large audience with extensive experience in joint projects in which Equinor has an interest and the right to decide/influence. Besides, I had been conducting interviews over a period of more than one year, and I had been informally speaking to the people with certain knowledge about the subject. Also, having looked through the corresponding publications during my MBA studies, I have managed to encapsulate the subject thoroughly, as well as understand the details and subtle differences pertaining to its essence and meaning.
