AkinÕs Laws of Spacecraft Design - #3<br />
Design is an iterative process. The<br />
necessary number of iterations is one<br />
more than the number you have<br />
currently done. This is true at any<br />
point in time.<br />

AkinÕs Laws of Spacecraft Design - #13<br />
Design is based on requirements. There's no<br />
justification for designing something one bit<br />
"better" than the requirements dictate.<br />
