I’ve been searching for the ultimate design tool for years. I’ve cycled between various software approaches (outliners, textfiles, wikis, diagrams, etc.) and through the many real-world alternatives. In the end, I’m more productive designing away from the machine.
Take my notebooks as an example. While they’re full of large sheets of paper, I don’t find them a useful place to think out design. They’re far too open, encouraging designs to grow prematurely. Blank sheets of paper are a bit better, as they allow for more rapid drafting (there is no need to rip out pages), but suffer from the same lack of constraint as notebook pages.
On the other side of scale, I’ve tried using different sizes of Post-its. They’re small, forcing a very productive economy of expression. They’re also handy for sticking to stuff, which allows the ideas to be moved about and related to each other (especially useful on a whiteboard). The greatest drawback to the Post-it is that they don’t archive well, making for a very temporary store.
Recipe cards, recently repopularized by the Hipster PDA meme, represent my ideal design form. I stopped using them several years ago in an attempt to go all-electronic (which crashed and burned), and am now getting back to their beautiful simplicity. They’re small, representing a sensibly-constrained, portable thought-space. They’re rugged, traveling well in my backpack, and can be tacked to a corkboard dozens of times before wearing out. They’re cheap, easy to find, and have many available forms of affordable long-term storage hardware. They also last for darn near forever, longer than even the average burned CDrom (in a format that’s always readable).
I still use electronic tools for tracking certain portions of design, just not for the early creative stages. I have to explored the design of a project in depth before I can start to document it with standard electronic tools, otherwise I just waste too much time mutating the design with inflexible tools.
