Authors are invited to submit in English, in all areas of Requirement Engineering. The program committee will blindly review submissions to that track. The author(s) name(s) and address(es) must not appear in the body of the paper, and self-reference should be in the third person. This is to facilitate blind review. The paper should not exceed 6 pages in ACM format. Please note that the maximum page length for the conference is 6 pages (without extra-fee), 8 is the maximum (with extra-fee). Submissions should be printable on a standard printer on common paper formats, such as US letter and A4. Papers should not be submitted to more than one ACM-SAC track. Paper submissions should be done electronically through the website at http://www.acm.org/conferences/sac/sac2015/Paper-SubmissionUploadPage.htm.
