If you want to ensure the originality of your content in your MBA dissertation, then one of the best ways is to conduct all of your research from scratch. It is always better to collect first-hand data for your dissertations, and it avoids any chances of plagiarism. You can even get assistance from https://mbaassignmenthelp.co.uk/mba-dissertation to assist you in your research. If you are adding someone else's work to your dissertation, just make sure that you give them proper credit with citations and references. You must always paraphrase that content. If you want to copy some lines as they are, then use quotations.
