Dealing with Ongoing Changes

Abstract

Kirk and Fred discuss the challenge of adding changes to a product during the development process so that they can design and build the prototypes.

Key Points

Join Kirk and Fred as they discuss how companies are adding new features to stay competitive with market developments.

Topics include:

• Automobiles, especially EVs, are excellent examples of the evolution of technology. They are increasingly complex and dependent on electronics.
• Product engineering changes after introduction to the marketplace are required for many reasons, such as when a component supplier discontinues a part and substitutes a new part. Testing the reliability of every change in a large manufacturing company is challenging.
• Sometimes, the simplest  designs are the most reliable and have the needed capabilities for most users. Many of today’s software applications have complex functional capabilities, yet most users do not need to access them.
• Engineering always has to deal with tradeoffs during each change in design or manufacturing and judgments about each risk. Many times, we have to make a fast decision on reliability risk based on experience, past field histories, and the collective knowledge of the engineering team.

Enjoy an episode of Speaking of Reliability. Where you can join friends as they discuss reliability topics. Join us as we discuss topics ranging from design for reliability techniques to field data analysis approaches.

Please click on this link to access a relatively new analysis of traditional reliability prediction methods article from the US ARMY and CALCE titled  “Reliability Prediction – Continued Reliance on a Misleading Approach”. It is in the public domain, so please distribute freely. Trying to predict reliability for development is a misleading a costly approach.
