Software Design For Reliability

With all the complaints you hear about products rebooting and software crashing, do companies really practice Software Reliability? In fact, there are some companies that do, but they are mostly in the industries that require products to have high availability, such as telecom, defense, and space, or safety-averse industries, such as medical and industrial plant operation. Most other industries don’t pay as much attention to it. The best method to increase Software Reliability without significant increases to schedules or budgets is to use a Software Design for Reliability (SDFR) approach. These are the key steps.

What is Criticality Analysis? How Does it Work?

Understanding the risks allow effective mitigation plans to be put in place

Where is your biggest risk to the site? If you can’t answer that, than your maintenance program is most likely not adequate. As previously discussed, an effective maintenance program must align with business and its needs. A criticality analysis allows the site to understand where there are risks that must be managed.

Nevada Charts to Gather Data

A common and poor technique to gather field data is to count the number of returns by week or month. This can provide a graph showing the number of returns over time.

It hides information you need to understand your field failures.

Let’s take a look at a way to gather the same field failure data and retain the critical information necessary for time to failure analysis. [Read more…]

What will Advance Reliability Engineering?

In all aspects of engineering we only make improvements and innovation in technology by building on previous knowledge. Yet in the field of reliability engineering (and in particular electronics assemblies and systems), sharing the knowledge about field failures of electronics hardware and the true root causes is extremely limited. Without the ability to share data and teach what we know about the real causes of “un-reliability” in the field, it is more easily understood why the belief in the ability able to model and predict the future of electronics life and MTBF continue to dominate the field of electronics reliability
