According to the method, a spreadsheet-driven key performance indicator is created that includes a location of a spreadsheet, a location of a cell within the spreadsheet to be utilized as an indicator value, and a goal value. The housing covers at least a portion of the connecting base and has a body and at least one fastening structure.
