Smart designers use a wide variety of tools where necessary. Limiting a team to only paper sketches or code may be more efficient. However, it also isn’t a bulletproof solution as iteration may become more difficult. Have you tried iterating with paper (copying / pasting / editing)? That actually may add unnecessary time. Electronic tools still have immense value. Absolute removal of prototypes? I don’t buy it. Minimalist processes may shave off minutes, but I would also pay attention to how quality is impacted.
I wonder how such UI toolkits shape the design thinking on your teams. Are you turning design into a purely drag-and-drop activity with bloatUI as a serious risk? Or are you also enabling people to question your UI toolkits? Ex. is anyone allowed to think that the “round trip” checkbox visible on your screenshot is even necessary? The article does not mention much about iteration. It seems like there was no iteration. The developer simply copied the sketch 1–1. Was anyone given the opportunity to ask a question such as: what is the relationship between the travel time and the profile picture on one of your screens? Design needs waves of synthesis, analysis, merging, adding, removal, and refactoring. That should not get lost.
The act of designing is a very interesting one needing flexibility. The tools we use enable conversations between the designer-and-her/himself, and between the designer and the team. Having a variety of design tools is key for this to happen. Forcefully limiting design tools also comes at the cost of limiting the richness of the design space.
And yeah. Agreeing with others, that this article has nothing to do with designing UX — which cannot be even designed as I understand it. UI can be designed, as they are given form and laced with intention. Most of what we experience is so unique and personal to each individual, that it’s best to stay clear of the arrogant notion of having “control” of someone’s else rich experience. At best, we may influence what others experience a tiny bit. Designing UI’s isn’t bad. :)
