Explaining an idea should be straightforward, although, in reality, it’s usually complicated. Looking at the world’s greatest minds, their abilities to simplify inextricably complicated concepts is astonishing. The capacity to describe something unconceived is ostensibly an inestimable skill to master.
Even in true “show, don’t tell” fashion. The potential for the idea’s inventor to overcomplicate the concept is real. Simplifying isn’t easy.
Adhering to lean principles, to get feedback on an idea as early as possible, measure the results, and build upon it is the way to go. If that means tinkering your way to an early prototype, be prepared to get your hands dirty. Improvise with paper, scissors, and glue if you must.
If you ship the first version of your product when you are satisfied with it, you have shipped too late. Confront your target audience with a very early manifestation of your idea. One that you’re both slightly ashamed of, yet audacious enough to show to the outside world.
