34.6 Scientific System diagnosis and Scientific Reasoning
At the root of successful system diagnosis is a rigorous adherence to scientific reasoning. There exists no single algorithmic approach to solving problems, but rather a singular mind-set characterized by the following traits: Curiosity Persistence Attention to detail Diligence in checking conclusions Regular checking of assumptions A willingness to abandon ideas based on contrary evidence Science is, at…

Chapter 34 Problem-solving and Diagnostic Strategies in Control System Analysis
The ability to solve complex problems is the most valuable technical skill an instrumentation professional can cultivate. A great many tasks associated with instrumentation work may be broken down into simple step-by-step instructions that any marginally qualified person may perform, but effective problem-solving is different. Problem-solving requires creativity, attention to detail, and the ability to…
