Warranty Analysis Folios

Despite best efforts to design and produce products that will last the expected lifetime, field failures are a reality. In order to anticipate customer needs and ensure customer satisfaction, there must be a process for studying field failures and correcting existing, as well as potential, reliability problems of fielded products. The analysis of warranty claims data is one such method.

Warranty claims data typically consist of quantities of units sold and quantities returned within a specified warranty period. Performing reliability calculations on this type of raw data can be tedious and time-consuming. To speed up your calculations, the Weibull++ warranty analysis folio is designed to convert your existing warranty claims data sets into failure/suspension data sets so that they can be easily analyzed with traditional life data analysis methods. In addition, the folio gives you the ability to predict future warranty returns so you can detect and correct potential product quality problems in the field and plan for warranty fulfillment needs, such as repair costs and the number of spares to stock.
