The fallacy refers to McNamara's belief as to what led the United States to defeat in the Vietnam War—specifically, his quantification of success in the war (e.g., in terms of enemy body count), ignoring other variables.
In 2014, I wrote about my belief that design and engineering are best when tightly woven together. That’s truer now than ever.
If I’m feeling confident, I’ll jump right into my text editor…From here, more functionality is added and the code is tweaked until the feature looks and feels right to me. Whether it’s something simple like this, or prototyping a new interaction like multi-connect, there’s no substitute for designing with real code.
In rare cases when I have ideas or plans that I’m less confident about, it’s time to break out the paper, pens, and markers,
Because the Kinopio interface elements and aesthetic are full-grown, I almost never use traditional design software anymore.
