Targeting a Customer Segment
Identifying Use Cases of Ideal Solution
Prioritizing via Functional Limitations
Creating an Information Architecture
Modularize Layout of UI
Designing Efficiency of Interaction
Let me cut you off right there. You are correct. There is no hard science behind design. However without some framework, design is downright impossible. Let’s leverage the best practices of [...]
In Part 1 of this post series, I discussed goal-directed design and the more customary way to view goals and tasks, along with their distinctions. In Part 2, I will lay down my claim about the true nature behind these conceptual tools. And in Part 3, the final part, I attempt to address the implications [...]
