ARM engineers use methods to test the different stages of the product as it progresses from research and development to its final stages of production. The cost involved in preparing a product and its reliability is also assessed.
Reliability methods assess the reliable of a product. Engineers use this method to formulate a specific analysis on a new product before it is tested. Essentially, reliability methods are only predictions, but they are still crucial as they help assess how reliable a product will be. Reliability of such products in space and defense sectors are crucial.
ARM engineers require and work with a variety of data that they use to assess the overall reliability, maintainability and availability of the product. Variables, continuity, limits and multivariable are a few examples. Most of the data is obtained through administrating productivity tests. The data is then put into a database and the engineer creates a summary of the results. This method helps bring together all the other tests and method uses to assess a specific product, and creates a final outcome on what needs to be addressed to increase productivity.
An important analytical method for ARM engineers involves maintainability methods. ARM engineers will develop maintainability methods and create goals regarding price objectives and production costs. Maintenance strategies, such as predicating maintenance, repair costs and shelf life of the product, are assessed and applied when creating an outline of production and maintenance cost.
