In my previous role as a Data Quality Coordinator, I often used Google Sheets for complex data analysis. One notable project involved analyzing patient data to identify trends in appointment delays. I utilized advanced formulas and pivot tables to organize and summarize the data, which allowed me to pinpoint specific departments that were consistently experiencing delays. By creating charts and visualizations, I was able to present these findings to the management team clearly. This analysis led to the implementation of targeted process improvements, which ultimately reduced appointment delays by 20%. This experience highlighted the power of Google Sheets in transforming raw data into actionable insights, driving operational efficiencies.
