  • Detailed fault codes and troubleshooting steps.
  • Offline functionality to ensure access in areas with limited connectivity.
  • User-friendly navigation and design.

Design and Architecture

System Architecture: The app's architecture was designed to ensure robustness and scalability. The backend was structured using a RESTful API to manage the extensive database of boiler models and associated fault codes. The frontend was planned to be responsive and intuitive, ensuring a seamless user experience.

Wireframing and Prototyping: The design phase began with wireframing and prototyping. Tools like Sketch and InVision were used to create detailed wireframes, illustrating the user journey and app functionalities. These prototypes were tested with a focus group to gather initial feedback and make necessary adjustments.

User Interface Design: Emphasis was placed on creating a clean and intuitive UI. The design team used a color scheme and typography that enhanced readability and user engagement. Icons and visuals were carefully chosen to represent different boiler models and fault codes accurately.

Development Phases

Technology Stack: The development team chose a technology stack that included:

  • Backend: Node.js and Express for the server-side, MongoDB for the database to handle the vast amount of data efficiently.
  • Frontend: React Native was selected for its cross-platform capabilities, ensuring the app could be deployed on both iOS and Android.

Agile Methodology: An Agile approach was adopted, with the project divided into multiple sprints. Each sprint focused on specific functionalities, allowing for iterative development and continuous feedback integration.

Database Development: The initial phase involved developing the backend database. Detailed data entry of boiler models, fault codes, and troubleshooting steps was undertaken. MongoDB's flexibility in handling unstructured data proved beneficial for managing the diverse information.

API Development: The next step was creating the RESTful API to facilitate seamless communication between the frontend and backend. The API was designed to be robust, ensuring quick data retrieval and smooth user experience.

Frontend Development: Concurrently, the frontend development team worked on integrating the UI designs with React Native. Components were built to handle the search functionality, display detailed boiler information, and provide offline access.

Testing Procedures

Unit Testing: Each component of the app underwent rigorous unit testing to ensure functionality and reliability. Automated tests were written to cover a wide range of scenarios, minimizing the risk of bugs.

Integration Testing: The integration of the frontend and backend was tested to ensure seamless data flow. Any discrepancies were promptly addressed, ensuring the app's components worked harmoniously.

User Acceptance Testing (UAT): A beta version of the app was released to a select group of users, including technicians and homeowners. Their feedback was invaluable in identifying usability issues and refining the app’s features.
