Low Fidelity Prototyping

This document explores the importance of low-fidelity prototyping in addressing common issues faced by fast-food restaurants during the ordering process. By utilizing quick diagrams to depict basic layout and flow, we can experiment with alternatives, gather rapid feedback, and resolve interface problems early. This approach helps save money while accommodating users unfamiliar with technology. Requirements include speeding up order placement, ensuring clear communication despite language barriers, and maintaining visual appeal. Work in groups to create and critique low-fi prototypes tailored to enhance the customer experience.

  1. Low Fidelity Prototyping CompSci 345 / SoftEng350

  2. Why Prototype • Experiment with alternatives • Quick feedback • Fix ‘interface’ problems early on • Saves money • Low Fidelity – Quick diagrams showing basic layout and flow • High Fidelity – Looks and works more like final product but with reduced functionality

  3. Plan for Today • Make a low-fi prototype (in groups of 4) • Keeping constraints in view • Share and critique our solutions

  4. Problem Statement • Customer is a fast-food restaurant, facing following problems while getting orders: • Verbal communication is prone to errors (especially in busy hours) • Language barriers • Customized orders have to be memorized and are often miscommunicated • Wants to automate “ordering” Adapted From: School of Information Management and Systems, University of California, Berkley

  5. Requirements • Accommodate users with no training • Speed in placing order is extremely important • System should help in swift order processing and delivery • The visual appeal of the food menu is also very important!

  6. The chief enemy of creativity • is ‘good’ sense. • Pablo Picasso
