Three Perfect Tools An Article by Tim Bray www.tbray.org There is a particular joy in a product that just does what you need done, in about the way you expect or (thrillingly) better, and isn’t hard to figure out, and doesn’t change unnecessarily. Here are three to learn from. toolsperfectiondesign
Apps Getting Worse An Article by Tim Bray www.tbray.org Too often, a popular consumer app unexpectedly gets worse: Some combination of harder to use, missing features, and slower. At a time in history where software is significantly eating the world, this is nonsensical. It’s also damaging to the lives of the people who depend on these products. ...Maybe we ought to start promoting PMs who are willing to stand pat for an occasional release or three. Maybe we ought to fire all the consumer-product PMs. Maybe we ought to start including realistic customer-retraining-cost estimates in our product planning process. We need to stop breaking the software people use. Everyone deserves better. It begins with craft uxsoftwareproducts
The Fidelity Curve An Article by Ryan Singer m.signalvnoise.com 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 fidelityTime to build versus confidence gained prototypesinterfaces
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 Show image 0 Show image 1 Show image 2 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.
