Blog Entry: Threat Modeling: How to Succeed at this High Value and High Effort Cybersecurity Activity
Threat Modeling (TM) is a process for identifying and prioritizing potential cybersecurity threats to software, hardware or a system. Contributing to the high value of TM is: The ability to identify threats early in the design process when they are less expensive to address Methodically prioritizing threats helps focus mitigation…
Recorded Webinars: How Does Mission Time Work with Proof Testing to Impact SIL Verification?
I have been asked this question many times by various clients over the years. This comes down to whether a perfect proof test is assumed or not. Let us remember that Mission Time is defined as the amount of time we expect a set of SIF equipment to run until a major overhaul is required, usually based upon the useful life of the devices. This time is set by the end user. Some companies are still not appreciating how greatly they will overstate the risk reduction of the Safety Instrumented Function (SIF) by assuming perfect proof testing since Mission Time then has no impact.
Therefore, what is perfect proof testing and what does this mean? We will discuss this among other things in this webinar.

Blog Entry: FMEA Evolution – Has the essence of FMEA been lost?
Has your FMEA entered the realm of the paperwork exercise that we force ourselves to do for no real reason than someone says we must do it? I have enjoyed analysis using FMEA. I first learned it existed when I was working for Ford. FMEA was the first Ford Technical…

Recorded Webinars: A Design Failure Mode and Effect Analysis (DFMEA) for Functional Safety
A Design Failure Mode and Effect Analysis (DFMEA) for Functional Safety-Design Deviation and Mitigation Analysis (DDMA)
A variation of the DFMEA method has evolved from the application of Functional Safety requirements to the DFMEA process. exida calls this method DDMA – Design Deviation and Mitigation Analysis. DDMA maintains the essential objective of DFMEA to identify potential design issues early in the development and make design changes to add important mitigations. DDMA substitutes information from functional safety engineering process steps thereby replacing work in the DFMEA. When expert knowledge is added to DDMA by using the ARCHxTM tool from exida to support this process, exida calls the method Design Expert Deviation and Mitigation Analysis (DexDMATM).
This webinar describes an evolution of the DFMEA process where some traditional items are not required and replaced by new items derived from Functional Safety standards.

Recorded Webinars: Faster, Better FMEDA – The Functional Failure Mode Process
The goal of performing a failure modes, effects, and diagnostics analysis (FMEDA) is to predict important reliability and safety metrics including failure rates for each failure mode, automatic diagnostic effectiveness, useful life, latent fault test effectiveness. This information is used for many purposes including identification of weak areas in a design, warranty cost prediction, etc. But perhaps most importantly, FMEDA results are used to calculate the safety integrity of equipment designed for Functional Safety applications. These safety integrity metrics are an essential part of functional safety certification.
As valuable as the FMEDA results are, many find that the engineering time needed to perform a quality FMEDA is excessive. How can we do better? There are several techniques that are used by top FMEDA professionals to not only reduce engineering hours but increase analysis quality. One of the most effective techniques is to organize the FMEDA input information into functional blocks, with functions and failure modes for each block documented. exida calls this the Functional Failure Mode FMEDA process.
