3 Key Questions Of Human-Centered Design

When we are dealing with something as complex as humans, it is best to keep things simple from time to time.

Human-centered design (HCD) is an approach to problem-solving that emphasizes empathy for users and their needs. It involves understanding the user's perspective, designing solutions that meet their needs, and testing those solutions with users to refine them. HCD is widely used in industries such as technology, healthcare, and education to create products and services that are user-friendly, effective, and impactful.

To keep it simple and common sense, we have deducted the entirety of HCD to its three most important questions:

But why is trend scouting so important, and how are companies leveraging it to stay competitive? Let's dive in.

Who are the users, and what are their needs?

The first step in human-centered design is understanding who the users are, what their goals and aspirations are, and what challenges they face. So, putting humans first starts from the first step of the HCD. This requires empathy and an ability to put oneself in the shoes of the user. By understanding the user's perspective, designers can create solutions that meet their needs and improve their experiences.

Therefore, the question "Who are the users, and what are their needs?" is a critical question in human-centered design because it helps designers understand the people they are designing for and what they need from the product or service being designed. By answering this question, designers can create solutions that are tailored to the user's needs and preferences, resulting in a better user experience and greater success for the product or service.

To illustrate the importance of this question, let's consider the analogy of a future bar owner who is about to open a new bar in a neighborhood. The bar owner may have their own personal taste in music and may want to play that music in their bar. However, to be successful, they need to consider the preferences of the people who will be frequenting their bar.

If the neighborhood has a younger population, the bar owner may want to play more modern music. If the neighborhood has an older population, the bar owner may want to play music from the 80s or 90s. By understanding the preferences of the neighborhood residents, the bar owner can create a more welcoming and enjoyable atmosphere that caters to their target audience.

In contrast, if the bar owner only plays the music they personally enjoy without considering the preferences of their target audience, they may struggle to attract and retain customers. By understanding the needs and preferences of their potential customers, the bar owner can create a more successful and sustainable business that meets the needs of their target audience. This is why understanding the users and their needs is critical in HCD.

What are the context and constraints of the problem?

Designers must also consider the broader context in which the user operates, including cultural, social, and economic factors. They also need to consider any constraints that may limit the design options, such as budget, resources, and technology. By understanding the context and constraints, designers can create solutions that are feasible, effective, and sustainable.

So, the question "What are the context and constraints of the problem?" is essential in human-centered design as it helps designers understand the broader environment and limitations that impact the problem they are trying to solve.

To provide an analogy, imagine you are building a house. The context of the problem would include factors such as the location of the house, the climate, and the surrounding environment. The constraints would include things like the available budget, building materials, and local building codes. All these factors would shape the design of the house, as they impact what is possible and what is desirable in the final product.

Similarly, in HCD, understanding the context and constraints of a problem is critical to creating a solution that is effective, feasible, and desirable. For example:

• Healthcare: When designing healthcare solutions, understanding the context and constraints is critical. For example, a design challenge might be to improve the patient experience in a hospital. The context might include factors such as the layout of the hospital, the types of medical procedures performed, and the needs of patients and their families. The constraints might include factors such as budget, staffing levels, and regulatory requirements. By understanding the context and constraints, designers can create solutions that are more effective and practical, such as redesigning the hospital layout to improve patient flow or providing patients with more comfortable and accessible amenities.
• Transportation: Context and constraints are also critical in transportation design. For example, a design challenge might be to create a more user-friendly transportation system for a city. The context might include factors such as the city's layout, traffic patterns, and public transportation infrastructure. The constraints might include factors such as budget, public opinion, and environmental impact. By understanding the context and constraints, designers can create solutions that are more effective and practical, such as designing a new public transportation system that considers the unique characteristics of the city and its residents' needs.

Understanding the context and constraints of a problem is critical in HCD to ensure that designers create solutions that are effective, feasible, and desirable.

How can we prototype and test the solution with users?

Finally, designers must iterate on their designs by creating prototypes and testing them with users to get feedback and refine the solution. Prototyping allows designers to quickly test and validate their ideas, gather feedback, and make improvements. By involving users in the design process, designers can ensure that the solution meets their needs and is intuitive and easy to use.

The question "How can we prototype and test the solution with users in relation to HCD?" is a critical step in the human-centered design process, as it allows designers to gather feedback and refine their solutions based on the needs and preferences of their target audience.

To provide an analogy, imagine you are trying to bake a cake for a friend's birthday. You start by researching different recipes and ingredients, and you decide on a recipe that you think will work well. However, before you bake the cake, you want to make sure that it will be a success. To do this, you might make a small prototype or test cake to see how it turns out. You might gather feedback from your friend on what they like and don't like about the cake and use this feedback to improve the final product.

Similarly, in HCD, prototyping and testing the solution with users is critical. Once designers have created a solution, they need to test it with real users to see how it performs in practice. This might involve creating a small-scale prototype of the solution and testing it with a group of users to gather feedback on how well it meets their needs and preferences. This feedback can then be used to refine the solution and create a final product that is more effective, feasible, and desirable for the target audience. For example:

• Car industry: To ensure that new car designs meet the needs and preferences of drivers, the car industry can prototype and test them with a group of users to gather feedback on safety and user-friendliness, which is a critical aspect of human-centered design. An analogy for this could be the use of crash test dummies in car safety testing - just as car manufacturers use crash test dummies to simulate the effects of a car crash and gather feedback on how to improve safety, they can also use user testing to refine the design and create a final product that is more effective at meeting user needs.
• Video game industry: To ensure that new games or features are enjoyable and engaging for players, the video game industry can prototype and test them with a group of beta testers to gather feedback on playability and user-friendliness, which is a crucial aspect of human-centered design. An analogy for this could be the use of focus groups testing a movie trailer - just as movie studios gather feedback from focus groups on a trailer to refine the marketing message and improve overall engagement, game designers can use user testing to refine the user experience and create a final product that resonates with players.

In summary, prototyping and testing the solution with users is a critical step in the HCD process, as it allows designers to gather feedback and refine their solutions based on the needs and preferences of their target audience, ultimately leading to more effective, feasible, and desirable products and services.

Closing, did you know questions.

Many leading companies focus on using HCD in their design process. Here are three examples of companies that use HCD and how they have benefited from it compared to traditional, product-oriented solution design:

• Did you know (why) Apple invented black mobile phone off-screens? Apple is known for its user-centric design philosophy, which emphasizes simplicity, elegance, and ease of use. Apple products are designed with the user in mind, and the company is constantly testing and iterating on its designs to improve the user experience. For example, the iPhone was designed with a touch-based interface that made it easy for users to navigate and interact with the device, but also with a black screen when it is turned off, so that you can see your face reflection in it, making it way more personal to us all. This was a departure from traditional phone designs, which relied on physical buttons and keypads, but was also considered just a tool before Apple truly upgraded it. As a result, the iPhone was a game-changer in the smartphone market and revolutionized the way we interact with technology.
• Did you know that computer mouse design is a HCD project by IDEO? IDEO is a design consultancy firm that employs human-centered design to create innovative and user-friendly products, services, and experiences for their clients. Using various design thinking tools and techniques, they identify user needs and create solutions to address them. In 1980, IDEO was tasked with designing the first computer mouse for Apple, which was an innovative solution that revolutionized the way people interacted with computers. By focusing on user needs and preferences, IDEO was able to create a product that was more intuitive and user-friendly, setting a new standard for computer design. How powerful and intuitive their design is can be seen in the fact that we still use computer mouses based on that design.
• Did you know that Airbnb was built on human-centered design? Airbnb is an online marketplace that connects travellers with local hosts who offer unique and affordable accommodations. Airbnb's design is focused on the user experience, with a simple and intuitive interface that makes it easy for users to search for and book accommodations. The company also uses HCD to continuously improve its platform, with features like instant booking and verified reviews that help build trust and reliability. Compared to traditional hotel booking platforms, Airbnb offers a more personalized and authentic travel experience that is tailored to the needs and preferences of individual users. It uses community co-creation methodologies like Design Thinking to include all stakeholders into the solution design process leading to constant innovation and change, which can be depicted in the number of times they adapted their logo in recent years.
