From the developer: Quality-Assist is a quality information management and analysis spc software program for statistical quality control with data from a variety of processes regardless of the type of product, service or industry. It provides tools to setup statistical process control, create a process knowledge base, display running records, analyze data distributions, summarize process nonconformance, calculate a randomized one factor analysis of variance and create defect pareto analyses. Process control establishes calculated control limits with process data and uses control limit run tests to detect the presence of assignable causes of variations from patterns in process data. The remaining tools provide diagnostic methods to identify sources of variations in process data to eliminate variations in processes and improve product quality.

Version 3.1.0 corrects observation record numbering for imported data with Individual Value/Moving Range and Moving Value/Moving Range processes having one observation per subgroup, where the observation number is the same as the subgroup number. There are other corrections and bug fixes.
