Requirements Elicitation

In the requirements literature there is a lot of confusion about termininology, which is perfectly fine, since this is a young discipline.  In addition, requirements engineering has been approached from different perspectives and viewpoints.

One point that brings different terminology and discussion is about Requirements Elicitation.

I believe that Requirements Elicitaton may be performed by three main strategies: 

1.  model-driven elicitation (where the elicitors gather what the syntax of the modeling language demands), 
2. uncompromised elicitation (where the elicitors gather information from the Universe of Discourse, without any predefined standard/language), and 
3. a mix of the two.

Another aspect that it is also confusing is: what is to be elicited.  Some authors make a distinction among requirements and domain. However, some  mix the idea of domain (a general knowledge that applies to several instances) to context information (knowledge specific to a given environment of a domain).

Although the term requirements have been a placeholder for different semantics, I opt for understanding that a  requirement is a sentence with a unique identifier. 

I gave a keynote talk at Istar'15 that tackles part of the issue: Elicitation Awareness in Conceptual Modeling: The Role of Transparency.

Below I list a series of papers that tackles the issue of Elicitation:
