Design Thinking: Human-Centered Innovation

Design Thinking is much more than a simple methodology; it's an approach, a mindset for solving complex problems that places the human at the center of the innovation process. Originating in product design, Design Thinking has been adapted for the business world as a way to develop products, services, processes, and strategies that are genuinely desirable by users, technologically viable, and financially sustainable. It contrasts with a purely analytical or engineering approach by incorporating empathy, collaboration, and experimentation at its core.

The Design Thinking process is generally divided into five phases, although it is not strictly linear and allows for iterations:

1. Empathize (Immersion): The first step is to put oneself in the user's shoes. This involves observation, interaction, and immersion in the problem's context to deeply understand their needs, pain points, and motivations, which are often unstated.
2. Define: Based on the learning from the empathy phase, the team synthesizes the information and clearly defines the central problem to be solved. The goal is to frame the challenge from the user's perspective.
3. Ideate (Ideation): This is the brainstorming phase, where the quantity of ideas surpasses quality. The objective is to generate a large volume of possible solutions for the defined problem, without judgment or criticism. Creativity techniques are used to think “outside the box.”
4. Prototype: The most promising ideas are transformed into low-fidelity prototypes. A prototype can be a drawing on paper, a cardboard model, a storyboard, or an app screen simulation. The goal is to tangibilize the solution quickly and cheaply.
5. Test: Prototypes are presented to users to collect feedback. This step allows learning what works and what doesn't in the proposed solution before investing significant time and resources in its development. The feedback feeds back into the process, allowing for refinement of the prototype or even returning to the ideation phase.

Real-world example:

A hospital team notices that elderly patients are having great difficulty managing their multiple medications, leading to dosage errors and poor treatment adherence. Instead of simply creating an app, they decide to use Design Thinking.

• Empathize: The team spends days observing the routine of elderly patients. They interview them, observe how they organize their medications, and talk to their family members and caregivers. They discover that the problem is not just remembering to take the medicine, but also the difficulty reading package inserts, opening packaging, and managing prescription renewals.
• Define: After immersion, they define the problem: “Elderly patients need a simple and safe way to manage the entire cycle of their medication, from purchase to consumption, so they feel independent and in control of their health.”
• Ideate: The team brainstorms. Ideas emerge such as an app with alarms, a smart pillbox, a delivery service for medications already separated by dose and time, and a voice assistant.
• Prototype: They decide to prototype the delivery service idea. They create an “experience box” with paper rolls containing the names of the medications, separated by day and time, and simulate how the delivery and interaction with the service would be.
• Test: They present the prototype to the elderly patients they interviewed. The feedback is extremely positive, but they suggest that the packaging have larger letters and a color system to differentiate morning, afternoon, and night. Based on this feedback, the team refines the solution and develops a pilot for the service. Design Thinking allowed them to create a solution that addressed the user's real pain point, resulting in a service with high adherence and social impact.
