Case Study: Oculus

Background

Pearson's internal Oculus application was conceived as a comprehensive platform for the configuration, publishing, and analysis of digital content across multiple channels, with a particular focus on eTexts and related digital assets. The platform's primary goal was to create a robust, scalable system that could meet the complex needs of content producers and publishers while seamlessly integrating with existing enterprise systems. Oculus aimed to provide an intuitive interface for managing various content types, ensuring consistency and efficiency across the board.

My role as the Product Manager was to oversee the platform's initial development, enhancement phases, and strategic growth, ensuring that it met the evolving needs of users and stakeholders while aligning with Pearson's broader business objectives.

Phase 1: Initial Development

Objective

The initial development of Oculus sought to establish a foundational platform capable of managing digital products, ensuring secure access, and providing basic analytics. This phase emphasized seamless integration with existing backend systems to facilitate efficient data retrieval and updates.

Key Features Developed

Product Libraries: Oculus introduced support for publishing to the eText platform from multiple authoring sources, allowing users to manage diverse content types and configure product settings as needed.
Publishing Capabilities: Oculus enabled publishing of eTexts either as standalone products or bundled as an element of other learning packages.
API-Driven Architecture: The platform's backbone was its API-driven architecture, which enabled flexible system integration and standardized digital content management.
User Authentication and Access Management: SSO (single sign-on) integration was implemented to secure platform access, allowing for effective management of various user roles and permissions.

Technological Foundations

Backend Development: Java and Spring Boot were selected for their maturity and scalability, complemented by MongoDB for flexible data handling and AWS services for robust, scalable storage solutions.
Frontend Development: React.js and Redux were chosen to create a dynamic, responsive user interface, with Node.js managing server-side operations to ensure seamless interaction between the frontend and backend.
DevOps and CI/CD: Docker and Jenkins were integrated to ensure consistency across development, testing, and production environments, streamlining the deployment process.

Challenges

Integrating with multiple backend systems while maintaining high performance and reliability.
Balancing the need for a robust backend with a responsive and intuitive user interface.

Phase 2: Platform Enhancement and Scaling

Objective

As Oculus evolved, the focus shifted towards enhancing its capabilities, improving user experience, and scaling the system to manage increased data volumes and more complex workflows.

Flexible Viewing Options: Users gained the ability to view and manage products in either Table or Grid View, with advanced filtering options by project and status, enhancing usability.
Detailed Product Configuration: The platform allowed for the configuration of features such as study tools, printing permissions, and audiobook settings, ensuring that products met specific educational requirements.
Comprehensive Analytics and Reporting: Oculus introduced detailed reporting capabilities on user engagement, product performance, and distribution metrics, driving informed decision-making.
Integration with External Systems: The platform was enhanced to support more complex integration scenarios and broader API support, expanding its reach and utility.
Enhanced Monitoring and Health Checks: Detailed health check APIs and monitoring tools like AWS CloudWatch were introduced to proactively manage and resolve issues.

Technological Enhancements

API Extensions: The API framework was expanded to support complex product management tasks and deeper analytics, enhancing the platform's utility.
Advanced Analytics and Monitoring:New Relic was integrated for comprehensive monitoring, ensuring optimal performance.
Security and Compliance: Transitioned to advanced systems like IES and AES for improved security management and compliance with industry standards.
User Interface Enhancements: Continuous improvements using React.js and Redux ensured that the platform remained user-friendly and efficient.
DevOps and Infrastructure Scaling: AWS Fargate was adopted for better scalability, while CI/CD pipelines were enhanced with Jenkins to support more frequent and reliable updates.

Challenges

Ensuring backward compatibility while introducing new features and API endpoints.
Managing the increasing complexity of the platform’s infrastructure as it scaled to handle more data and users.

Phase 3: Future Enhancements and Innovations

Focus Areas

Artificial Intelligence and Machine Learning: Integrating AI/ML capabilities to offer predictive analytics and personalized user experiences, driving more dynamic and responsive content management.
Microservices Architecture: Further decoupling platform components to enhance scalability, flexibility, and maintainability, allowing for modular development and easier updates.
Real-time Analytics: Implementing real-time data processing to provide instant insights and feedback, improving the platform's responsiveness and relevance.

Outcomes
