To approach the task of consolidating data from multiple departments into a single Google Sheet dashboard for IT infrastructure monitoring, I would begin by gathering data requirements from each department to understand the specific metrics and data points they track. This ensures that the dashboard will be comprehensive and meet everyone's needs. Next, I would collect the data from each department, ensuring that it is clean and standardized for easy integration. Using Google Sheets, I would employ pivot tables to summarize and organize the data efficiently. VLOOKUP would be instrumental in linking related data points across different datasets, ensuring that all relevant information is connected accurately. Additionally, I would use charts to visually represent key metrics, making the dashboard intuitive and easy to interpret. Throughout the process, I would focus on maintaining data accuracy and integrity, regularly validating the data to prevent errors. Finally, I would collaborate with department heads to review the dashboard, ensuring it meets their expectations and making adjustments as necessary to optimize its functionality.
