| "We were looking for a knowledgeable person/company to come in and give a 2 day seminar in order to train our Reliability Engineers on the basics of HALT/HASS and Reliability Integration. Ops A La Carte provided exactly what we asked for in a very professional manner, and they were open to modifying the presentation based on our Company's specific needs. Our Engineer's gave positive feedback on the seminar and stated that they now have the knowledge, and are comfortable with going out and performing HALT on our products. We would definitely refer Ops A La Carte to other companies and may bring them back for periodic refresher training."

HALT, HASS, and HASA Applications
OBJECTIVES
Specifically targeted for those with the basic education in HALT, HASS, and HASA to show how to apply the techniques on products. We have also introduced the topics of Reliability Demonstration Testing and Accelerated Reliability Testing for comparison purposes.

WHO SHOULD ATTEND
This course is intended for those involved in HALT and HASS on products and need a better understanding on how to apply these principles to your particular products. This seminar will be application oriented with case studies and examples in over 50 different industries. The material for the course is based on HALT and HASS results on over 500 products.
