A new version of the JM-SPC computer program written by J. Mutwil in Delphi for statistical control of production processes is presented. All changes have been by users suggestions caused. For the attribute valued data type most of new features have been joined to data introducing option. In this way the program allows to consider a wider data spectrum. Usefulness of the introduced solutions for statistical analysis of the attribute valued data type gained from real processes has been presented on the example of Al-Si high-pressure die casting production. The analysis refers to a serial produced casting and includes: 1) the analysis of defect fraction in sample (by using the p-chart), 2) the analysis of relative differences in importance of each defects categories (by using of the Pareto diagram).
