What is Human Centred Design?
Human Centred Design is a problem-solving approach that develops solutions by taking the human perspective and behaviour into consideration at every level of the design. Its goal is to address and incorporate the preferences, pain points, likes, and dislikes of the user. It was first popularised by the global design firm IDEO who found that the Human Centred Design approach led to quicker, increased profits and fewer products failing to market. It starts with the end-user for whom the solution is being designed and ends with a tailor-made solution that is suitable to their requirements. A product may typically meet either a functional, emotional or social need. The functional need is the actual use of the product whereas the emotional and social needs come from the feeling one gets from possessing a product. For example, it could meet an aesthetic or status need.
The Human Centred Design approach is akin to the ‘Jobs to be done’ theory by Harvard Business School Professor Clayton Christensen’s which states that people do not buy a product, but hire it to do a specific job or achieve a particular goal. The Human Centred Design approach looks at the design through this framework of the users’ motivations rather than demographic attributes such as income, gender, age, etc.
The Human Centred Design is so popular in that it has been defined in ISO 9241-210:2019(E) as “an approach to interactive systems development that aims to make systems usable and useful by focusing on the users, their needs and requirements, and by applying human factors/ergonomics, and usability knowledge and techniques. This approach enhances effectiveness and efficiency, improves human well-being, user satisfaction, accessibility and sustainability; and counteracts possible adverse effects of use on human health, safety and performance”.
It has three phases, viz., the inspiration phase, the ideation phase, and the implementation phase. The Inspiration Phase entails interacting with and learning from the end-user. The designer immerses himself totally into the lives of the people he is designing for, so as to understand their context and need. This will remove preconceived notions, biases, misunderstandings about what the customer actually requires. It sort of gets buy-in from the end-user. This stage requires empathy to understand the emotions and experiences of the customer. It is the designer putting himself into the shoes of the customer, getting a feel of the product asking questions that the customer would ask such as where, when, or the purpose for which they use the product. The ideation phase is used to generate various ideas and prototypes based on the experiences from the inspiration phase. The implementation phase would involve bringing the solution to the end-user.
Salient Features
The salient features of Human Centred Design are that it needs empathy, the generation of a large number of ideas through brainstorming or bodystorming, creation of a large number of prototypes along with the end-user.
It caters to the functional, emotional, and social needs of the end-user right from the start.
Product designs that follow the HCD approach are generally successful in the market. On the downside, these products have a long lead time for development.
Benefits
Even though the time to design and produce the product takes time, the likelihood of the product succeeding in the market is very high.
Having been designed from the perspective of the end-user, the product has early acceptance in the market.
Examples
Zoom.
Zoom realized the increased need for videoconferencing solutions not only for businesses but educational institutions, religious organizations, individual trainers, etc. Zoom created the virtual learning system through interaction with teachers and students and designed a system that met the varied end users’ requirements. Zoom ensured security and compliance requirements due to young students using its platform, they further build a whiteboard for easy interaction, dashboards to track student engagement, and integration with various learning management systems
Products used during Commutes
Designers of products used during commute such as coffee, milkshakes, mobile phones, music devices, etc, have interacted with the end-user to make their products more acceptable to the end-user. For example, Bluetooth-enabled hands-free mobile phones, music player controls on the steering wheel, cup holders in the car, increasing the thickness of the drink have been incorporated into the product based on the end-user requirements.
Changing Users Requirements during Covid
Payment and Logistics. With the onset of the pandemic, people had a need for reduced cash payments and increased home delivery of items. Payment and logistics processes have been redesigned to cater to these specific user requirements.
Electronic Tablets. Tablets were basically being used by the designer community. However, during Covid, the customer base extended to teachers, students, managers, etc. Wacom identified this requirement and through interaction with the end-user incorporated various hardware and software changes in their offerings.
