Explanation: A storyboard is a visual representation of a user’s journey with a product or service. It shows how the user interacts with the product or service in a specific context, what their goals and pain points are, and how the product or service solves their problems or meets their needs. A storyboard typically consists of a series of sketches or illustrations that depict the user’s actions, thoughts, and emotions at each step of the journey1. A storyboard is the most suitable technique for CK’s UX Designer to use in this case, because it can help them communicate their innovative solution to the team and show where and why it fits into what the customer does. A storyboard can also help the UX Designer to validatetheir assumptions, test their ideas, and get feedback from the team and the customers. Astoryboard can also inspire the team to generate more ideas and solutions, and align them with the user’s perspective2. Personas are fictional characters that represent the potential users of a product or service. They are based on user research and data, and they describe the user’s demographics, behaviors, motivations, goals, and frustrations. Personas are useful for understanding the user’s needs and expectations, and for designing products or services that cater to them. However, personas alone are not enough to show how the user interacts with the product or service in a specific context, or how the product or service solves their problems or meets their needs. Personas need to be complemented with other techniques, such as scenarios, user stories, or storyboards, to illustrate the user’s journey3. A high-fidelity prototype is a realistic and interactive simulation of a product or service. It mimics the look, feel, and functionality of the final product or service, and it can be used for testing and evaluation purposes. A high-fidelity prototype is useful for demonstrating the features and benefits of a product or service, and for getting feedback from the users and stakeholders. However, a high-fidelity prototype is not the best technique for showing where and why a product or service fits into what the customer does, as it focuses more on the details and specifics of the product or service, rather than the context and situation of the user. A high-fidelity prototype is also more time-consuming and resource-intensive to create than a storyboard, and it may not be necessary at the early stages of the design process.
