Let me clarify this. If I encounter inconsistent and incomplete data from a department midway through a project, my first step would be to pause any ongoing analysis to prevent further inaccuracies. I would then identify the specific inconsistencies and gaps in the data. This involves reaching out to the concerned department to gather the missing information and clarify any discrepancies. Once I have the necessary data, I would clean and validate it to ensure its accuracy. After updating the data, I would revalidate the entire dataset and update any reports or dashboards to reflect the corrected information. This approach ensures that the final reports are comprehensive and reliable, supporting accurate decision-making.
