Interesting Lecture Notes: Akin’s Laws of Spacecraft Design
Keeping up with the latest advances in engineering can at times feel like the field is iterating faster than anyone can fully evaluate it. Just as things may start to feel comfortable, there’s another round of new tools and capabilities, which can also be equal parts exhilarating and exhausting. It is, by any measure, an uncanny period when the frontier is moving faster than the understanding behind it.
This encroaching shift in the craft of engineering makes for a direct juxtaposition with safety-critical systems, where the margin for error hasn’t moved (and will not), and neither has the value of expertise earned over time and often the hard way.
Akin’s Laws of Spacecraft Design are 45 rules on engineering and project management, drawn from a career spent designing spacecraft and learning, by the author’s own account, what not to do. David Akin first wrote the list as a handout for his senior capstone design course; an abridged version now hangs framed in Mission Control at NASA Johnson Space Center.
These are some bits of wisdom that I have gleaned during that time, some by picking up on the experience of others, but mostly by screwing up myself. I originally wrote these up and handed them out to my senior design class, as a strong hint on how best to survive my design experience… — David Akin, Professor of Aerospace Engineering at the University of Maryland
Of the 45, a handful of favorites that hold as fundamental tenets of engineering.
Analysis and engineering:
1. Engineering is done with numbers. Analysis without numbers is only an opinion.
17. The fact that an analysis appears in print has no relationship to the likelihood of its being correct.
Understanding design requirements:
13. Design is based on requirements. There’s no justification for designing something one bit “better” than the requirements dictate.
3. Design is an iterative process. The necessary number of iterations is one more than the number you have currently done. This is true at any point in time.
Schedules:
23. The schedule you develop will seem like a complete work of fiction up until the time your customer fires you for not meeting it.
33. (Patton’s Law of Program Planning) A good plan violently executed now is better than a perfect plan next week.
The full list is worth reading in its entirety, with additional meta-commentary on each law. For a manufacturing specific companion, the University of Florida’s 110 Tips for DFMA covered in a past issue pairs well.
