It is a little world
- Cubed
In the 1960s, the designer Robert Propst worked with the Herman Miller company to produce “The Action Office”, a stylish system of open-plan office furniture that allowed workers to sit, stand, move around and configure the space as they wished.
Propst then watched in horror as his ideas were corrupted into cheap modular dividers, and then to cubicle farms or, as Propst described them, “barren, rathole places”. Managers had squeezed the style and the space out of the action office, but above all they had squeezed the ability of workers to make choices about the place where they spent much of their waking lives.
...It should be easy for the office to provide a vastly superior working environment to the home, because it is designed and equipped with work in mind. Few people can afford the space for a well-designed, well-specified home office. Many are reduced to perching on a bed or coffee table. And yet at home, nobody will rearrange the posters on your wall, and nobody will sneer about your “dog pictures, or whatever”. That seems trivial, but it is not.
The brick is one of those old technologies, like the wheel or paper, that seem to be basically unimprovable. ‘The shapes and sizes of bricks do not differ greatly wherever they are made,’ writes Edward Dobson in the fourteenth edition of his Rudimentary Treatise on the Manufacture of Bricks and Tiles. There’s a simple reason for the size: it has to fit in a human hand. As for the shape, building is much more straightforward if the width is half the length.
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.
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.
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.
