Abstract :

In the era of Covid-19, people are more sensitive to their health and hygiene. SAC is present in the community as a service to clean each customer’s favourite shoes. Even though SAC has been around since 2013, until now they have not touched the digital realm. For this reason, innovation for SAC needs to be implemented so they are not left behind by competitors who are starting to become aware of digitalization. So that the implementation of digitalization can save costs and time, the approach to making digital products is through product development. To innovate through the use of product development in digital, a User-Centered Design (UCD) method approach with a Design Thinking (DT) mindset is used. The UCD process includes understanding context, specify user requirements, design solution, and evaluate. With the DT mindset, the process of emphatizing, defining, and ideation is applied to the understand context and specify user requirements so that this research will understand the usability side for users. With the addition of 5 UCD elements from Jesse James Garret, the digitalization process will be more in-depth and detailed in terms of creating interface design solutions. Primary data will be collected through In-depth Interview resulting abundant data that create persona and Minimum Viable Product(MVP). This research aims to analyze and identify the user experience flow for the prototype mobile web app product design SAC with the identifying the MVP and design prototype mobile website application and later do some usability testing to getting result that can meet the needs and uses for SAC customers. The result of this design approach method is a high-fidelity mobile web app prototype which was evaluated using Usability Testing (UT). The persona of each customer and the desire are the first key in development. Strong framework is formed with information architecture, low-fidelity, and high-fidelity prototypes. The final stage of the UCD iteration is to evaluate Usability Testing with a binary task success rate of 90%. Another UT results of quantitative data analysis with the Single Ease Question (SEQ) showed the number 6.42 and the System Usability Scale (SUS) showed the number 87.5 with quality A.
