Importing Data from Excel Files to DOE++
DOE++ gives the user the ability to create Standard Folios by importing data from files created by other applications. The file types that available for import are: 1. Tab, Comma, Space and Semicolon delimited files (*.txt, *.csv, *.prn, *.smc) and 2. Excel files (*.xls). This article provides a simple step-by-step guide for importing data sets created in Excel.

Statistical Tests for Effectiveness of Corrective Actions in RGA 7
During a multi-phase reliability growth test, failure modes are discovered and corrective actions are implemented during or at the end of each phase. Although growth between phases can be tracked in terms of comparing MTBF or failure intensity, how can we verify that the observed growth (if any) is statistically significant or, in other words, that the corrective actions have been effective in eliminating the failure modes? In this article we present a new tool in RGA 7 that explores the effectiveness of corrective actions during or at the end of a phase.
