Every computing system has two, and only two attributes: Data Value and Data timing, which represent fully the system functionalities from the system external behavior point of view.
The data driven system engineering is the approach to develop the system by focusing on the two attributes mentioned above, in which, the data values are derived by the system operation concept design, and the data timing is derived by the system latency design. Based on which, this book provides a full range of system and software engineering development activities.

The author, James Wen, and any associated entities make no representations or warranties of any kind, express or implied, regarding the accuracy, completeness, reliability, or suitability of the information contained herein, including but not limited to discussions of system operation concepts, error detection (limited to data value and timing errors), failure mode and effect analysis (FMEA), safety developments, cybersecurity approaches, verification processes, or any examples (e.g., automotive ECU integrations). All content is based on the author's experience and is not guaranteed to produce specific results.
NOT PROFESSIONAL ADVICE: This book is not intended as, and should not be construed as, legal, engineering, safety, or professional advice. It does not guarantee compliance with any standards (e.g., ISO 26262 for functional safety or UN ECE 155/156 for cybersecurity), regulations, or industry practices. Custom approaches (e.g., optimized FMEA or recursive data derivations) are conceptual and may not align with all regulatory requirements. Readers are solely responsible for ensuring their implementations meet applicable laws, standards, and safety criteria.
