# Testing & Simulation

A Test and Simulation strategy involves defining the “right” mix of each to ensure a design/process is optimized and is meeting both its internal and customer requirements. An appropriate strategy minimizes test risk, is based on accurate simulation of the operational environment, and cost-effectively applies available resources.

## Environmental Stress Screening: Basic Steps in Choosing an ESS Profile

November 26th, 2008
Environmental Stress Screening (ESS) is the process of exposing a newly manufactured product to environmental stresses in order to identify and eliminate latent defects introduced during the manufacturing process. It is part of the manufacturing process and is therefore performed on 100% of the items manufactured.   Read More

## Design of Experiments for Reliability Improvement

July 26th, 2007
Many times we want to improve Reliability (or other Quality characteristics) by way of increasing positive and reducing negative factor effects that influence performance.   Read More

## Test Samples: How Many Are Needed?

April 26th, 2007

For demonstrating product reliability the question of how many test samples are needed to be “X” percent confident of having met a reliability objective often comes up. Let’s say that manufacturer is going to produce 5,000 rooftop car carriers and is willing to tolerate roughly 100 returns over the next five years. How can this…  Read More

## Probability and Statistics for Reliability: An Introduction

March 26th, 2005
Painful as it is to many of us, the generally desirable product characteristicReliability is heavily dependent on Probability and Statistics for measuring and describing its characteristics. This edition of Reliability Ques will only be the tip of the iceberg in this regard. Let’s start with a few basics:   Read More

## Using Accelerated Life Testing to Assess Warranty Risk

October 26th, 2002
During a recent project, a question arose about the feasibility of providing a ten year warranty for a new system. The system consisted of a proven electronic assembly and 40 newly designed hybrid electronic modules. Warranty costs could be significant if reliability risks were not fully understood. The company producing the system   Read More
