Our Designing Approach

Bulb case study user research

User Research

Conducted in-depth user research to understand customer needs and preferences.

User Personas:  Created detailed user personas based on demographic information, behavior patterns, and pain points to better empathize with the target audience.

Surveys and Interviews: Conducted surveys and one-on-one interviews with potential users to gather qualitative and quantitative data, uncovering their motivations, challenges, and expectations.

Competitor Analysis: Analyzed competitors’ products to identify gaps in the market and areas where our app could offer a unique value proposition.

Usability Studies: Organized usability studies to observe how users interacted with existing solutions or prototypes, providing insights into usability issues.

Wireframes & Prototypes

Designed wireframes and prototypes to visualize the app’s structure and functionality.

Information Architecture: Carefully crafted the information architecture to ensure intuitive navigation and a logical flow of content within the app.

Low-Fidelity Wireframes: Developed low-fidelity wireframes to outline the basic layout and content structure, allowing for early validation of concepts and ideas.

High-Fidelity Prototypes: Created high-fidelity interactive prototypes using tools like Sketch, Figma, or Adobe XD, enabling stakeholders to experience the app’s functionality before development.

Iterative Design: Incorporated user feedback into multiple rounds of iteration, refining the prototypes to address user pain points and improve usability.

UI & Backend Integration

Developed the UI design while seamlessly integrating it with the app’s backend systems.

Visual Design: Crafted a visually appealing and cohesive user interface, ensuring consistency in branding, color schemes, typography, and iconography.

Responsive Design: Ensured that the UI design was responsive and compatible with various devices and screen sizes, providing a consistent user experience.

API Integration: Worked on integrating the front-end UI with the backend systems, ensuring smooth data flow and real-time updates as needed.

User Testing

Rigorously tested the app with a diverse group of users to gather feedback and ensure optimal user experience.

Test Scenarios: Developed test scenarios and scripts to guide users through specific tasks and interactions within the app.

Beta Testing: Launched a beta version of the app to a select group of users, collecting real-world feedback and identifying any critical issues or bugs.

Usability Metrics: Gathered usability metrics such as task completion rates, time on task, and user satisfaction scores to quantitatively assess the app’s performance.

Feedback Analysis: Analyzed user feedback and behavior to identify pain points, bottlenecks, and areas of improvement, informing further design iterations.

Bulb Energy Wireframe

Collaboration with Developers

Worked closely with the development team to align backend functionality with user requirements.

Regular Communication: Maintained open and regular communication channels with developers, ensuring that design and development were aligned throughout the project.

Agile Methodology: Utilized agile development methodologies, such as Scrum or Kanban, to facilitate continuous collaboration and adapt to changing requirements.

User-Centered Development: Advocated for a user-centered development approach, where user needs and feedback were prioritized during sprints and feature implementation.

Prototyping for Development: Provided developers with detailed design specifications, assets, and interactive prototypes to streamline the implementation process and reduce misinterpretation of design intentions.

User Personas

We create user personas that go beyond demographics, to help us grasp the user’s current situations, pain points, and behavior patterns, which helps us uncover their needs & goals and allows us to create products that resonate with them.


User Journeys

We proceed to map out user journeys within our product, to help us visualize the paths users take to complete specific tasks. This helps us to gain insights into how to improve the overall user experience and provide users with added value.


User Flows

These visual diagrams serve as a bridge between user journeys and design implementation by illustrating the step-by-step path users follow to accomplish tasks within the website, helping us create an intuitive and efficient navigation system.



With a solid understanding of user needs and an optimized user flow, we move on to creating wireframes. Wireframes are skeletal representations of the product’s layout and structure, allowing us to prioritize functionality without visual distractions.



Once wireframes are finalised, we breathe life into the product by refining layouts, applying colors, selecting typography, and adding content, with accessibility as a core consideration at every step of the UX and UI design process.
