That’s a wrap! We got a walkthrough of foundational design methodologies and best practices, with an understanding of the key principles underpinning UI and UX design. Even as methodologies go in and out of vogue, core concepts, such as putting users at the center of design and iterating according to feedback, will never go out of style.

Here’s a summary of what we’ve covered:

  • UI and UX methodologies offer structure and consistency to focus on problems, drive execution, and define success within a design process.
  • The double diamond model illustrates two modes of thinking that occur during the strategy and execution stages of the design process. The four phases of the double diamond process are: discover, define, develop, and deliver.
  • Divergent thinking explores many possible solutions and generates novel ideas, and convergent thinking analyzes, filters, and focuses ideas to make decisions.
  • The product development life cycle (PDLC) is a cross-functional, iterative process that can be viewed as 5 stages: brainstorm, define, design, test, and launch.
  • Design thinking puts people at the center of every process and encourages designers to set aside assumptions to solve complex, multi-dimensional wicked problems. The five stages of the design thinking process are: empathize, define, ideate, prototype, test, across three core activities: ideation, inspiration, and implementation.
  • User-centered design (UCD) is an iterative process that puts users at the center of product development and involves them in the design from the beginning. User-centered design processes generally involve the following activities: understand, specify, design, evaluate.
  • The UX Honeycomb diagram defines “good” UX design as useful, usable, desirable, findable, accessible, credible, and valuable.
  • The ten usability heuristics are a set of ten general principles for good interaction design.
  • User research is the systematic study of target users of a product or interface to understand their behaviors, needs, and motivations. User research can happen at every stage of the design process to inform decisions.
  • Methods of user research include quantitative user research, qualitative user research, attitudinal research, behavioral research, and usability testing.

Next, we’ll be exploring the career landscape of UI and UX design jobs!
