Recognizing Constraints An Article by Jeremy Wagner css-tricks.com Super Nintendo games were the flavor of the decade when I was younger, and there’s no better example of building incredible things within comparably meager constraints. Developers on SNES titles were limited to, among other things: 16-bit color. 8 channel stereo output. Cartridges with storage capacities measured in megabits, not megabytes. Limited 3D rendering capabilities on select titles which embedded a special chip in the cartridge. Despite these constraints, game developers cranked out incredible and memorable titles that will endure beyond our lifetimes. Yet, the constraints SNES developers faced were static. You had a single platform with a single set of capabilities. If you could stay within those capabilities and maximize their potential, your game could be played—and adored—by anyone with an SNES console. PC games, on the other hand, had to be developed within a more flexible set of constraints. I remember one of my first PC games had its range of system requirements displayed on the side of the box: Have at least a 386 processor—but Pentium is preferred. Ad Lib or PC speaker supported—but Sound Blaster is best. Show up to the party with at least 4 megabytes of RAM—but more is better. constraints
Don’t Be an Ostrich An Essay by Chuánqí Sun medium.com You just handed off a major redesign. Three months of research, twenty-seven major revisions, and hundreds cups of coffee have all culminated in this pinnacle of glory. It’s finally done! Except it’s not. It’s not, even after you have answered every single question the developers have about your red-line. It’s not, even after you have addressed all the technical constraints developers encountered during the implementation. It’s not, even after you meticulously documented all the patterns and styles into a library for reference and reuse. It’s not, because neither you nor the developers have talked to a real user. At the bottom of your heart, you are secretly wishing: My design looks great on paper, so let’s keep it on paper. You are an ostrich. Post-occupancy evaluation
Post-occupancy evaluation Post-occupancy evaluation (POE) is a practice in the building industry where an architect would visit the building after its occupancy and interview its residents. It sounds like a great opportunity for collecting feedback and learning from mistakes, but it’s rarely practiced. Why? Many awe-inspiring, prize-winning architectures are half building, half sculpture. Often made of specially molded concrete and steel, they are extremely expensive to alter, let alone any alteration would also attack the architect’s prestige and pride. So whatever usability issues the POE identifies will remain as issues, unless the architect wants to accept the public criticism and shame that comes with the remodeling. In fear of criticism, an architect would turn down the opportunity for POE, and continue to design the same roof that would leak water in future projects. In fear of criticism, a developer would use customer service representatives as a shield against user complaints, while focusing on the “technical” aspect of things. In fear of criticism, a designer would close the contract as soon as the client accepts the design, even though none of the real users are represented by the client. architectureux
