The most expensive design mistakes aren’t visual — they’re structural. A misplaced button costs an hour to fix; a misunderstood user flow costs a sprint. That’s why every UI project at Codefumes starts rough on purpose.
Fidelity is a budget
Think of design fidelity as money you spend to answer questions. Sketches answer “is this the right flow?” for almost nothing. High-fidelity mockups answer “does this feel right?” at ten times the cost. Spending high-fidelity money on flow questions is how projects burn budget before development starts.
The three-pass process
- Pass one: boxes and arrows. Every screen as a labelled rectangle, every action as an arrow. This is where we find missing states — empty lists, errors, loading — while they cost minutes to add.
- Pass two: clickable wireframes. Grey boxes wired together so a real person can attempt a real task. Watching one user hesitate is worth ten internal reviews.
- Pass three: visual design. Only now do brand, typography, and colour enter. The flow is already proven, so visual iterations stay visual.
Accessibility starts in the wireframe
Contrast and focus states can be fixed late; a flow that requires drag-and-drop as its only path cannot. We check keyboard paths and reading order at the wireframe stage, when the fix is a redrawn arrow instead of a rebuilt component.
What clients get from this
Fewer surprises, mostly. By the time development starts, the product has already been “used” dozens of times on paper. The build phase becomes execution rather than discovery — which is exactly where you want your development budget to go.
