Design Principles: Don Norman's Design Principles, Jacob Nielsen’s Usability Heuristics, Christopher Wicken's Display/Control Principles
Concepts: Personas, Hierarchical Task Analysis, Fault Tree Analysis, Heuristic Evaluation, Human Factors
This project focused heavily on the process of proper design methodologies. In groups of 4, we delivered 3 main stages of redesign analysis. In stage 1, we created primary and secondary personas, listed user requirements, and outlined various safety, performance, and preference requirements.
Here's a frontal picture of the original product, with a sample of our initial comments:
In stage 2, we dove into how to improve the product. To do this, we performed hierarchical task analysis as well as fault tree analysis to determine how users use the product, and where it was prone to failure. To formulate redesign ideas, an in-depth analysis was performed by comparing the product to Don Norman's Design Principles, Jacob Nielson's Usability Heuristics, and Christopher Wicken's Display/Control Principles.
Among other techniques used, we created this fault tree analysis (FTA) to determine potential points of failure in the original product.
Finally, we compiled a list of redesigns in response to the information gathered, and created a computer rendered image of the conceptual redesign.
