Using PI AF to standardize and replicate calculations and analyses SunCoke Energy operates six sites in the US and Brazil for the conversion of metallurgical coal into metallurgical coke used in the manufacture of steel. The core technology and data points used across the coke oven batteries have remained consistent across the sites leading to common analytical points and spreadsheet tools. However, people change. Spreadsheets evolve. Variations begin. By using AF and the Analytics, we begin to bring the calculations back to standard, bring the spreadsheets into PI, and allow our people more time for performance improvement rather than spreadsheet improvement. AF feeds our Business Intelligence.
