Originality problems often begin when a sample or template becomes the source of the wording rather than a guide to structure. Your report should be based on your own project facts and written in your own voice.
Generic duty lists are another risk because the same phrases can appear across many documents. Replace broad statements with accurate explanations of the work you performed and the decisions you made.
A similarity result needs interpretation. Common technical terms may appear naturally, while a longer matched passage may need to be reviewed and rewritten from the underlying facts.
Never change a passage only to defeat a checker. Preserve the true meaning, verify every claim, and use current official guidance when preparing your submission.
