Join David Hogue for an in-depth discussion in this video Design thinking, part of UX Foundations: Interaction Design.
- [Narrator] Design thinking is the name we give to exploratory and iterative methods where we seek to understand people and their problems, needs, and expectations, to identify and challenge our assumptions about our products and the people who use them, and to generate alternative strategies and solutions for better products and services. Design thinking is effective when we are facing problems that are vague, or not yet understood. Although there are multiple models for design thinking, they often share these steps.
We observe and empathize with people to understand their problems and needs. We watch how they work and interact with products and conduct research to understand their goals and methods. We explore many possible solutions, evaluate them, and identify the best designs and prototypes. After we converge on the best solutions, we build and deliver effective products. And we iterate continuously for improvement and innovation. One of the most common design thinking models is the double diamond, which illustrates the process of repeatedly generating multiple ideas, then identifying and narrowing down to the best.
In the first phase, we focus on discovering as much information as possible to help us define and clarify the problem. In the second phase, we generate, explore, and test many possible solutions, identify the best, then build and deliver it to the people who need it. These methods encourage us to diverge and converge, which is a form of abductive reasoning. Generate many possible solutions, evaluate them, then choose the best.
We've discussed dimensions and models of interaction design, but one of the most common ways we describe the goals of our work is with guiding principles. These principles keep us focused, give us a framework for making decisions that put people first, and provide a mechanism for evaluating the quality and performance of the products we design. We strive to understand people and the context in which they interact with a product or service, to define the purpose of a product or a service by understanding people's needs and goals, craft an efficient flow through a product or service to help people reach their goal, ensure the products and services are meaningful, relevant, and valuable, ensure the products and services are easy to use, learn, and remember, and respect and protect the people who use our products and services.
Interaction designers work as members of a larger team, where each contributes to the overall product. Design, business, and technical decisions can all affect the product experience. Difficult interfaces, prioritizing revenue over people's needs, or implementing with inadequate technologies can all result in poor quality and bad experiences. We are collectively responsible for the quality of the products and experiences we deliver.
