To identify and resolve missing or incorrect data entries in an MIS report, I would start by conducting a thorough review of the data sources and cross-referencing them with the report. I would use data validation techniques to pinpoint discrepancies. For missing entries, I would trace back to the original data source to ensure all data is captured accurately. If the data is incorrect, I would verify the data entry process and correct any errors. I would also implement automated checks and alerts in Google Sheets to flag potential issues in the future. Collaboration with relevant departments would be essential to ensure data integrity and address any systemic issues contributing to these discrepancies.
