Communication skills have been highlighted as among the most important skills to be conquered by the engineering graduates. As new industrial revolution strikes in, engineering graduates are required to relearn and upgrade their generic skills to remain significant in the challenging working environment. Previous studies have identified the attributes of communication skills, but those attributes may not be relevant anymore; thus, there is a need to identify the current attributes of communication skills for IR 4.0 engineering graduates. Therefore, this study was done to derive the traits/attributes of communication skills using systematic review method considering previous studies from 2006-2019. A crosswalk of seven previous researchers was produced in this study. Emerging themes from the crosswalk are ability to effectively speak with audience; ability to convey a clear written communication; ability to communicate with people from different background; ability to deliver presentations; ability to express own idea; and ability to listen and give appropriate feedback. Findings of the study will provide a significant set of attributes in communication skills for IR 4.0 engineering graduates and embark the opportunities for further research by the authors.
