Stepping out of the firehose
An Article by Benedict EvansIn 1800, if you’d said that you wanted something ‘made by hand’, that would be meaningless - everything was handmade. But half a century later, it could be a reaction against the age of the machine - of steam and coal-smoke and ‘dark satanic mills.’ The Arts and Crafts movement proposed slow, hand-made, imperfect craft in reaction to mass-produced ‘perfection’ (and a lot of other things besides). A century later this is one reason I’m fascinated by the new luxury goods platforms LVMH and Kering, or indeed Supreme. How do you mass-manufacture, mass-market and mass-retail things whose entire nature is supposedly that they’re individual?
...we keep building tools, but also we let go. That’s part of the progression - Arts and Crafts was a reaction against what became the machine age, but Bauhaus and futurism embraced it. If the ‘metaverse’ means anything, it reflects that we have all grown up with this now, and we’re looking at ways to absorb it, internalise it and reflect it in our lives and in popular culture - to take ownership of it. When software eats the world, it’s not software anymore.

The Fidelity Curve
How do we choose which level of fidelity is appropriate for a project?
I think about it like this: The purpose of making sketches and mockups before coding is to gain confidence in what we plan to do. I’m trying to remove risk from the decision to build something by somehow “previewing” it in a cheaper form. There’s a trade-off here. The higher the fidelity of the mockup, the more confidence it gives me. But the longer it takes to create that mockup, the more time I’ve wasted on an intermediate step before building the real thing.
I like to look at that trade-off economically. Each method reduces risk by letting me preview the outcome at lower fidelity, at the cost of time spent on it. The cost/benefit of each type of mockup is going to vary depending on the fidelity of the simulation and the work involved in building the real thing.
Four levels of fidelity
Suppose we have four levels of fidelity…
- Rough sketch (on paper or an iPad)
- Static mock-up (eg. Photoshop or Sketch)
- Interactive mock-up (eg. Framer, InVision)
- Working code prototype (HTML/CSS, iOS views)
Depending on the feature you’re working on, these levels of fidelity take different amounts of time to create. If you plot them in terms of time to build versus confidence gained, you could imagine something like a per-feature fidelity curve.
Time to build versus confidence gained
Take a simple CRUD web UI, where you’re just navigating between screens. It doesn’t take much more time to build the real version than it does to mock it when the design is simple. If you were to build out an interactive mock first, you would end up spending twice as much time in total without gaining much out of it.
Contrast that with a complicated Javascript interaction. Or a native iOS feature that requires programmer time to build out. If it takes substantially more time to build the real code version, then it may be smart to do an interactive mockup first.
