Dealing with Changing Requirements

Abstract

Kirk and Fred discussing the dynamics of changing a design during the development process. The longer it takes to develop a new product the longer it allows the competitors to introduce new features and functions, which may have more market appeal than your products features right as your finishing development.

Key Points

Join Kirk and Fred as they discuss adding and changing features and how it affects the reliability in the long term.

Topics include:

• Getting a product with new features to the market is a big factor in making a new market required feature for competitors, such as making smartphones more water resistant forces other smartphone makers to do the same.


• Rapid development component technology also makes adding new features, such as electronic cameras once relatively expensive becoming a chip so inexpensive it can be added to many lower costs products.


• Thermal HALT of high speed digital systems is especially beneficial in signal propagation issues and soft failures, as conductivity is inversely proportional to temperature in most materials. High temperature slows and low temperature speeds up electrical signals.

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.
