First, by reviewing my database's security procedures, which require that the original be kept over the modified and/or assessed version. After that, the colleague's information is assessed by peers (geologist and petrophysicist). Finally, based on the results, the individual is confronted.

Understand the Importance of QA/QC: Quality Assurance (QA) and Quality Control (QC) are crucial in geology to ensure data reliability. QA involves setting up systems and procedures to maintain high standards, while QC checks the accuracy and precision of the data. Any tampering undermines these processes and can lead to poor decision-making based on unreliable data. Verify the Data: Before raising concerns, double-check the data thoroughly to rule out other explanations, such as a data entry error or a calculation mistake. Accurate data is critical for geological assessments, and it’s the role of QA and QC to detect and correct these issues early.
