  Build one to throw away means you're building the same "system" again, but with more specific requirements based on what you learned.

The biggest mistake in the 'Build one to throw away' concept is that it implicitly assumes the classical sequential or waterfall model of software construction." He wrote a later book, The Design of Design, encouraging iterative development.)
