1. Overview
1. Attempt to introduce the importance of functional safety through two everyday examples. 2. Comparative analysis of how to build a car that is recognized as safe by everyone. 3. Brief introduction to related concepts of functional safety, clarifying the logical relationships among these concepts. 4. Since “functional safety” is a relatively large topic, this article will briefly discuss the concept of “functional safety” and deeply understand its essence.

3. Example 1: How to Make a Delicious and Hygienic Bowl of Noodles
1. Chain brands 2. Quality service 3. Reasonable prices 4. Open and transparent kitchen/supply chain
4. Example 2: How to Determine if a Postdoctoral Researcher is Truly Talented
1. Prestigious universities 2. Excellent grades 3. Journal papers 4. Professors’ professional recommendations
5. How to Build a Car that is Recognized as Safe by Everyone
1. Big brands 2. High sales 3. Celebrity endorsements? 4. Live factory broadcasts? 5. Launch events?
It is evident that simple things like “openness and transparency” can improve quality and build trust; complex/professional matters require “professional authority” to ensure quality and enhance trust.
6. Functional Safety
“Functional safety” defines the safety-related functions used in the development process, as well as the processes, methods, and tools that must meet requirements to ensure that a sufficient level of safety is achieved and maintained throughout the entire lifecycle.

7. Conclusion
- The essence of “functional safety” is trust and authority.
- “Functional safety” defines the safety-related functions used in the development process, as well as the processes, methods, and tools that must meet requirements to ensure that a sufficient level of safety is achieved and maintained throughout the entire lifecycle.
- Documents, compilers, chips, environments, software standards, testing processes, etc., are highly relevant to embedded engineers.
- Does the military/aerospace require “functional safety”?
