3.  The selection of suitable RE techniques  appropriate use of RE techniques leads to high quality requirements specifications, which in turn results in high quality software products.  The method is developed by:  Dr. L. Jiang,  Dr. A. Eberlein,  Dr. B.H. Far, &  Dr. M. Mousavi.

4.  It aids requirements engineers in establishing a link between the attributes of the project and the attributes of RE techniques.  based on the detailed analysis and comparison of RE techniques.  The objective function used in the approach provides an effective decision support mechanism for the selection of RE techniques.

5.  High frequency of errors in requirements activities (Ambrióso et al., 2009).  Identify what techniques are needed to avoid failure (Macaulay, 1996).  Attributes effect quality and cost of a project (Jiang et al., 2008b).  Limitations of RE techniques for Geographical distribution (Ahmad et al., 2011)  Requirements engineering techniques could be used to generate policy (Callele & Wnuk, 2011).
