Wire harness development and testing Slow is painful by Jon M Quigley Vehicle Systems Vehicles have become increasingly electrical over the year, even vehicles that are not electric propulsion.  There are more features, more embedded controllers and greater communication between the electronic controllers.  The range of content is from power electronics, sensor data (analog signals), […]

We are composing a glossary of test terms and we take one from that work today and discuss here. A development organization can be structured in many ways. The development and testing can be essentially one department under one management structure, or these two areas, development and test can be separated each with a respective […]

Verification and Validation The definition for verification and validation can be found at[1]:   We must express some disagreement with the activities associated with the individual areas. For example, testing is not limited to Validation. Testing is also a function of verification as we will use these techniques to understand if the instantiation of the […]

Testing Complex and Embedded Systems What set of conditions could cause this event to occur? When we have elicited all we can from the customer about fault information, it is time to proceed further in our analysis. This next step requires investigation of the design to understand how the symptom of failure described could happen […]

It is not even handing the customer our results and patting everybody […]

Testing and System Complexity System and software complexity, […]
