Claim management presents complex challenges for organizations, from claims intake to member management and policy administration. The architecture supporting these processes plays a crucial role in this intricate landscape. As the claim management landscape evolves, the pressure on legacy monolithic architectures grows, prompting organizations to seek innovative solutions.
A well-designed claim management system can help businesses to:
Process claims more efficiently, leading to faster customer payments and improved cash flow.
Reduce the risk of errors, improving customer satisfaction and avoiding costly fines.
Adapt to changing regulations more quickly, helping businesses stay compliant and avoid penalties.
Scale to meet a growing business's needs without investing in a new system.
Alchemists Solutions, a provider of claim management solutions, operates a legacy claim management system based on a monolithic architecture. While the monolithic claim management system has served them well for years, its limitations have become apparent as claim volumes have risen. The monolithic architecture complicates adding new features, slowing down innovation. It also hinders scalability, leading to performance bottlenecks and customer dissatisfaction.
Modernizing the claim management system presents a challenge for Alchemists Solutions. They need a solution that's scalable, reliable, and easy to maintain. A potential solution is a microservices architecture, which breaks down an application into smaller, independent services for easier changes and efficient scalability.
Alchemists Solutions has begun modernizing its claim management system, exploring options that best suit its business. The impact of monolithic architecture on their existing processes will be a critical factor in their decision-making.
Alchemists Solutions' Monolithic Architecture
A monolithic n-tier architecture divides the application code into n logical layers. These layers are organized based on functional responsibilities: user interface (UI), business logic, data access, and infrastructure. While the layers are logically separated, they are not physically separated.
Alchemists Solutions uses a system of self-contained monoliths to orchestrate the entire claims lifecycle. This allows for independent development and expertise but makes collaboration, change, and agility difficult.
Here are some critical challenges Alchemists Solutions faces with its system of autonomous monolith subsystems:
Lack of clear contracts between subsystems: This can lead to communication problems.
Difficulty collaborating effectively across teams: Coordinating changes is hard.
Challenges in being agile: Changes in one subsystem may require changes in others, hindering adaptability.
Alchemists Solutions must consider these challenges when planning and executing their strategies and architectures.
Understanding the Subsystems
The claims management system comprises various subsystems collaborating to process claims from intake to initiation.
Claims: The central hub manages tasks like claim validation, assignment to adjusters, and meticulous claim progress tracking. It collaborates with other subsystems to gather critical information for comprehensive claim processing.
Member: Manages enrollment, billing, and payment functions for members. This includes creating and updating member profiles, processing payments, and generating billing statements. The member subsystem also stores member data, such as contact information, insurance coverage, and medical history.Alchemists Subsystems
Policy: Governs policy dispute creation, updates, and resolution. It provides the claims system with vital policy-related data, such as limits, deductibles, and copays, determining claim eligibility.
Document Generation: Ensures the generation of essential documentation, including claim forms, letters, and reports. It collaborates with the claims system to provide accurate and up-to-date documentation.
Payment: Disburses funds to members and providers. It collaborates with the claims system to access claim details and member insurance information for payment processing.
Document Storage: Acts as a repository for claim forms, letters, reports, and critical documentation. It provides the claims system with access to this documentation when needed.
Claims Processing: Represents a legacy engine orchestrating batch claim processing at day's end. It executes critical business logic to ensure accurate and efficient claim processing.
Customer Service: Manages customer service for members and providers, ensuring satisfaction with the claims management process.
Reporting: Generates reports on claims data, aiding in tracking trends and identifying improvement areas.
This overview provides a high-level view of the various subsystems of a claims management system. The specific components and implementation details may vary depending on the insurance company or organization. This overview is for illustrative purposes only and should not be taken as an accurate representation of any particular claims management system.
Anatomy
The anatomy of a monolith can be divided into these layers:
The UI layer facilitates interaction between the application and users.
The Facade layer provides a unified interface to the application's business logic.
The business logic layer houses the core functionality.
The data access layer retrieves data from the database.
The choice of UI rendering approach depends on the application's specific requirements.
Server-side UI rendering: The UI is rendered on the server and sent to the user's browser as a static HTML page. This is the simplest and most common approach to UI rendering in monoliths.
Client-side UI rendering: The user's browser or mobile app renders the UI. The monolith provides a facade that the UI can use to interact with the application's business logic and data access layers. This approach is more complex to implement but offers more flexibility and scalability.
Components
UI Component (I1, I2, I3, ..., In):
These user interface elements facilitate interaction between the application and users. They encompass various user interface parts, such as forms, views, and user interaction logic.
Facade Component (C1, C2, C3, ..., Cn):The facade component(s) serves as an entry point or intermediary layer, simplifying the interaction between the UI and underlying business logic. It abstracts complexity, providing a unified interface to UI components.
Business Logic Component (C1, C2, C3, ..., Cn):
This component houses the core business logic of the application. It processes user requests, enforces business rules, and coordinates interaction among application parts. Despite being part of the same monolith, components might organize by different functional domains.
Data Access Components (C1, C2, C3, ..., Cn):
Data access components (DAOs) provide a layer of abstraction between the business logic and the data tier. They abstract data retrieval and other operations, such as creating, updating, and deleting.
Data Tier (T1, T2, T3, ..., Tn):
The data resource tier is a logical grouping of data sources available to a monolith. It is accessed via data access components in the monolith, responsible for retrieving and persisting data from the data resource tier.
In a monolith, these components coexist within a single codebase. UI Components interact with the Facade Comonents, communicating with Business Logic Components. The Business Logic Components leverage the Data Access Components to persist and retrieve data as needed from the Data Resource Tier.
The System is a function of the UI, facade, business logic, data access, and data tier components. The interconnectedness of these components is one of the monolith's defining characteristics.
UI(c1, c2, ..., cn) represents the User Interface components.
F(c1, c2, ..., cn) represents the Facade components.
B(c1, c2, ..., cn) represents the Business Logic components.
D(c1, c2, ..., cn) represents the Data Access components.
S(c1, c2, ..., cn) represents the Data Resource Tier components.
The equation represents the interconnectedness of these components. The UI, business logic, data access, and infrastructure components are all interconnected and interdependent. Changes to one component can affect the others.
For example, if the UI changes, the business logic may need to be adjusted. If the data access component changes, the business logic may need to adapt to the new data access methods.
Monoliths face challenges like scalability and maintainability as applications grow. This has led to alternative approaches like microservices, breaking applications into smaller, more manageable components.
Drawbacks of Alchemists Solutions' Interconnected Monolith
