STATGRAPHICS Sigma express is designed as an add-in for Microsoft Excel, providing users with the tools necessary to perform calculations required when learning or applying Six Sigma methodologies. By adding a dedicated menu selection within Excel, it organizes functions according to the DMAIC paradigm (Define, Measure, Analyze, Improve, and Control), supplemented by additional tools and help resources. The capabilities included in Sigma express are comprehensive enough to meet the requirements of green belts and a significant portion of black belts in executing Six Sigma calculations directly within Excel. Furthermore, its interface and functionality closely mirror those of STATGRAPHICS Centurion, facilitating a seamless transition for users who require more advanced statistical capabilities in the future. Users can select data directly from their Excel worksheets and display results in a STATGRAPHICS analysis window with multiple panes for tables and graphs. The output can then be pasted back into the worksheet or into other applications like Word or PowerPoint.
