Provide a discussion on ERP. As part of your discussion, you should explain the inherent weaknesses in the design and functionality of ERP system and how ERP vendors can do to overcome these weaknesses; the barriers that may hinder organizations to implement ERP system and corrective mechanisms that can mitigate those barriers; how management accounting information/systems/processes affect or are affected by ERP system and finally how ERP system can contribute to the development of sustainable business. To complete these questions, you are required to search relevant scholarly papers (please note that Wikipedia is not a good source to find reference papers and you are highly recommended to use Google Scholar instead) or business articles to get some ideas.
