Personas
Creating user personas for a DAS system involves understanding the diverse needs and characteristics of potential users. Here are two sample user personas:
Design
User Flow
Wireframe
sketches
After creating a to-do list for designing the key screens identified in the task flow and user flow, I started sketching low-fidelity screens. I can capture my ideas by pen and paper quickly by sketching. It also enables me to examine my ideas before putting everything in the daunting process of digitizing.
Mid-Fidelity Wireframes
Transitioning from initial sketches to mid-fidelity wireframes allowed me to refine the user interface, emphasizing visual consistency and hierarchy. Incorporating proven design patterns from competitors ensured alignment with industry standards, while integrating elements tailored to users’ goals and motivations. This stage facilitates collaborative feedback, ensuring a polished and user-centric design for the bullion store platform.
Usability Testing
Prior to initiating usability testing, establishing clear test objectives, defining the test subjects, outlining the methodology, specifying tasks, and formulating rubrics for result evaluation are crucial steps. Consequently, I crafted a comprehensive usability testing plan to articulate the testing goals, the rationale behind the evaluation, and to adequately prepare for the upcoming test.
I proceeded to perform usability testing with a sample of 3 participants.. Detailed test cases were generated for each participant, documenting their interactions with the prototype. These test cases capture instances of mistakes, slips, and expressed confusions, providing valuable raw data for summarizing and analyzing patterns in user interaction with the prototype.
Branding
Before diving into style design, I created a mood board on Pinterest to gather multiple inspirations around the specific attributes extracted from the project brief:
Project Objectives:
Brand Representation: Reflect the client’s brand identity through the store’s design, incorporating colors, logos, and overall aesthetics that align with the company’s image.
Customer Experience: Prioritize a welcoming and secure environment for customers. Design an intuitive layout that facilitates easy navigation and product discovery. Consider the creation of interactive displays or information kiosks to educate customers on precious metals.
Security Measures: Implement robust security measures to ensure the safety of valuable inventory. Integrate advanced surveillance systems, alarm systems, and secure storage solutions.
Transaction Areas: Design dedicated spaces for transactions, consultations, and customer interactions. Ensure privacy for high-value transactions, while maintaining transparency in the buying and selling process.
Product Display: Develop creative and visually appealing display solutions for showcasing various precious metals. Consider lighting and materials that enhance the attractiveness of products without compromising security.
Based on this I created a branding guide with main colours being yellow and black which visually represents the project brief The combination of black and yellow in the bullion store theme suggests a harmonious blend of richness, elegance, and positivity. It creates a visually appealing environment that communicates the store’s focus on valuable commodities while maintaining an optimistic and secure atmosphere for customers engaging in precious metal transactions.
High-Fidelity Wireframes & Prototype
By applying established styles, I crafted high-fidelity wireframes that enable a thorough examination of the application’s overall aesthetic appeal and visual balance. This stage allows for a detailed assessment of the design’s look and feel, ensuring a cohesive and visually pleasing user interface.
Final Thoughts + Next Steps
Having reached the final prototype milestone for the Driver Advisory System (DAS), I am confident that the initial objectives established at the outset of the design process have been successfully realized.
