💻Design Strategy and Software I Unit 3 – User–Centered Design

What's User-Centered Design?

• Focuses on designing products, services, and experiences around the needs, goals, and preferences of the end-users
• Involves understanding users' behaviors, motivations, and pain points through research and empathy
• Aims to create intuitive, efficient, and satisfying user experiences by putting users at the center of the design process
• Considers users' physical, cognitive, and emotional characteristics when designing interfaces and interactions
• Iterative approach that involves continuous user feedback and refinement throughout the design and development process
• Helps ensure that the final product meets users' expectations and requirements, leading to higher user satisfaction and adoption
• Differs from other design approaches (technology-driven or business-driven) by prioritizing user needs over other considerations

• Observations: Watching users interact with a product or perform tasks in their natural contexts
  • Can be conducted in-person or remotely using screen-sharing and recording tools
  • Helps identify usability issues, workflow inefficiencies, and opportunities for improvement
• Focus groups: Moderated group discussions with users to gather collective insights and opinions
  • Involves bringing together a diverse group of users to discuss their experiences, preferences, and expectations
  • Helps identify common themes, concerns, and design opportunities
• Diary studies: Longitudinal studies where users record their experiences and interactions with a product over an extended period
  • Involves providing users with a structured template or prompts to document their daily experiences
  • Helps understand how users' behaviors and needs evolve over time and in different contexts
• Usability testing: Observing users as they perform specific tasks with a product or prototype to identify usability issues and areas for improvement
  • Can be conducted in-person or remotely using screen-sharing and recording tools
  • Helps validate design decisions and ensure that the product is intuitive, efficient, and satisfying to use
• Card sorting: A technique where users organize and categorize information or features into logical groups
  • Can be conducted using physical cards or digital tools
  • Helps inform information architecture, navigation, and content organization decisions

Personas and User Scenarios

• Personas: Fictional characters that represent the key user types and their characteristics, goals, and behaviors
  • Based on research insights and data about real users
  • Helps designers and stakeholders empathize with users and make user-centered design decisions
  • Typically includes a name, photo, demographic information, goals, motivations, and pain points
• User scenarios: Narratives that describe how a persona would interact with a product to achieve a specific goal or task
  • Helps designers understand the context, steps, and outcomes of users' interactions with the product
  • Identifies key touchpoints, pain points, and opportunities for improvement in the user journey
• Benefits of using personas and scenarios:
  • Provides a shared understanding of users among the design team and stakeholders
