But, first, let's explore the concept. Let's say that, in the first idea, the "position" was to be stated in a document called "paper", but, we decided to first, set as Position Paper but we decided to downgrade it to a less challenging "report".

The concept

The third milestone happens in the middle of the "doctoral path". Within that date, Candidates are expected to almost complete their formal training activities (Courses) and to have clear ideas about their future. If so, they can start working "shoulders to the wheel" on their PhD Thesis and (they have just an year to produce their first draft) will be able to put on the table a first version - reasonably completed - to be discussed in their last Deep Review Meeting (MILESTONE FIVE).
At the end of their first year each Candidate have defined and discussed their Research Project (presented in the MILESTONE TWO meeting) in a short complete report stating the exact position, i.e the 
essay that presents an opinion about an issue – typically that of the author or some specified entity. Position papers are published in academia, in politics, in law and other domains. A position paper presents an arguable opinion about an issue. The goal of a position paper is to convince the audience that your opinion is valid and worth listening to. Ideas that you are considering need to be carefully examined in choosing a topic, developing your argument, and organizing your paper.
Position papers range from the simplest format of a letter to the editor through to the most complex in the form of an academic position paper.[1] Position papers are also used by large organizations to make public the official beliefs and recommendations of the group.[2]
The five-paragraph fetish Writing essays by a formula was meant to be a step on the way. Now it’s the stifling goal for student and scholar alike
