The design, acquisition, and operation of products and systems intended for defense applications must understandably meet some of the strictest reliability standards of any industry or sector. When it comes to a mission-critical apparatus, failure of any type can lead to unacceptable and devastating consequences. For this reason, the Department of Defense’s (DoD) Reliability, Availability, and Maintainability (RAM) guidelines and the U.S. Military’s reliability prediction handbook (MIL-HDBK-217) were established.
With the incredible pace of innovation in the fields of electronics and microelectronics, as well as the increasing adoption of highly sophisticated technology in military equipment, the need for enhancing defense system reliability has never been greater. This is why, for professionals ranging from reliability managers to quality engineers, having the right defense system reliability software tools like the impressive suite of tools included in the Relyence Studio is a prerequisite for success.
Compliance, performance, and ease of access are built into every analysis tool we provide. This means our suite of tools is ready from day one to work intuitively with the teams using them — resulting in a better ROI and streamlined workflow, all while enhancing defense system reliability.
DoD Guidelines Recognize Need for High Reliability, Availability, and Maintainability
It’s no secret that the U.S. Military always aims to be superior in its equipment and technology. Yet along with innovation, setbacks and failures occurred when components and equipment were not up to the task at hand. Ultimately, the DoD issued RAM guidelines to “acquire quality products.” Yet, even as recently as 2015, the Director of Operational Test and Evaluation (DOT&E) reported to Congress that a mere 38 percent of components and systems “met their reliability requirements.”
To successfully meet the requirements of their contracts, defense suppliers need to employ the best and most compliant reliability software package on the market today. This is why Relyence is such a trusted name among today’s leaders in the defense sector. To enhance reliability in the military and defense industry, you want software applications that are specifically built to withstand the most demanding challenges of the defense industry. Simply put, you want Reliability Excellence – you want Relyence.
