  • Improves operational efficiency, customer experience, market competitiveness.
  • Incremental implementation of modular architecture makes the transition from legacy systems smoother.
  • Long term benefits - easier adoption of new technology, compliance.

The State of Legacy Systems in Insurance

Legacy systems are the core systems of many insurer’s IT estates. These monolithic systems built decades ago handle policy administration, claims, customer relationship management. But now they can’t keep up with the pace of change in the market and technology.

Many insurers are still using outdated technologies like COBOL based mainframes. While these systems are stable, they are not flexible and agile enough to keep up with today’s business demands. Integration issues, inefficiency and outdated architecture makes modernization difficult and insurers are stuck with systems that can’t use modern technology.

Problems with Legacy Systems

Inflexibility 

As companies add more products or enter new markets, these systems can’t scale. Updating or adding new features often requires full rewrites, extending development cycles and increasing risk of failure.

Maintenance costs 

They require specialist skills, often in outdated languages, and talent retention is expensive. The inefficiency of these systems means slow processing, manual intervention and higher error rates and operational costs.

Research shows that legacy systems in the insurance industry often consume 70-80% of IT budgets, leaving little room for innovation. Their complex, outdated architecture makes system changes slow and costly, with some insurers taking up to 18 months to launch new propositions. The maintenance of these systems hampers agility, creating significant barriers to innovation.

Integration with modern technology

As the industry goes digital, insurers can’t easily add AI, machine learning or blockchain to their legacy infrastructure. Without modern APIs integration is cumbersome and limits innovation and customer satisfaction improvements. Insurance legacy system transformations has to search for another route like complete system overhaul risking downtimes or creating entire system from scratch, which results in enormous costs.

Security vulnerabilities and compliance issues 

Legacy systems lack advanced security features and are more vulnerable to cyberattacks. Keeping up with changing regulations, especially in data privacy is a challenge. 

Compliance requires significant system changes and more IT resource strain.

Limited customer experience capabilities 

It means insurers can’t compete in today’s market missing on valuable insights. Outdated legacy systems don’t support the seamless, personalized experiences customers expect and puts insurers at a disadvantage to other industries.

Modernizing Legacy Systems with Modular Architecture

Modular architecture is the solution to the legacy system problems making insurance legacy system transformation easier. This approach breaks complex systems into smaller, independent modules that focus on specific business functions like claims or customer management. These modules can be developed, deployed and maintained separately for more flexibility and scalability.

Comparison of Modular Architecture vs. Monolithic Architecture

Feature Modular Architecture Monolithic Architecture
Structure Composed of independent modules that can be developed and deployed separately. Built as a single, tightly integrated unit.
Development Allows for parallel development; teams can work on different modules simultaneously. Development is linear; changes affect the entire application.
Deployment Individual modules can be deployed independently, reducing downtime. Requires redeployment of the entire application for any change.
Scalability Easier to scale specific modules as needed. Scaling often requires scaling the entire application, which can be inefficient.
Maintainability Improved maintainability due to separation of concerns; easier to update individual modules. Maintenance can be cumbersome as changes in one part may affect others.
Complexity More complex in terms of architecture but less operational complexity compared to microservices. Simpler to develop initially but can become complex as the application grows.
Resource Utilization Modules can share resources efficiently, reducing overhead. Resource utilization may be inefficient due to tight coupling of components.
Flexibility Offers flexibility to adapt and integrate new technologies over time. Less flexible; adapting to new requirements often requires significant rework.

This incremental approach is enabling insurers to replace parts of their legacy systems without disrupting the whole estate. It minimizes the risk of a big bang and allows insurers to prioritize system upgrades based on business needs.

Modular Architecture Solves Legacy System Issues

Modular architecture solves the inflexibility of legacy systems. Independent modules can be updated or replaced as needed and insurers can scale and add features faster. This agility allows insurers to respond to market changes better.

The cost benefits of modular architecture is another big competitive advantage. Modular architecture eliminates the need for expensive legacy system maintenance. It supports modern technology and reduces training and support costs. Automation of manual processes like claims handling improves operational efficiency and reduces costs. Over time this means big savings.

Insurance companies that implement modular systems often experience a 35-40% reduction in cost-to-serve due to improved processes and reduced reliance on legacy systems.

Customer data security and compliance also improves with modular systems. Modern modules have advanced security features like encryption and access controls. Compliance with changing regulations is more manageable, as individual modules can be updated or replaced to meet new requirements. This is especially important in the heavily regulated insurance industry.

Implementing Modular Architecture in Insurance

Moving to modular architecture requires planning. A incremental approach is often the best way. Insurers should start by identifying high impact areas like customer facing systems or core processing modules and prioritize based on business value and technical feasibility.

Start with non-critical systems and teams can get experience with the new architecture which builds confidence and provides valuable learnings for later stages. Each successful implementation reduces the risk of big changes.

Data migration and system integration is a challenge that needs to be managed. Data integrity throughout the process is key, as is managing the integration between old and new systems. Staff training is also essential for a smooth adoption, and insurers should prepare for resistance to change. Clear communication and focusing on the tangible benefits of modular systems will help overcome these challenges.

The Future of Insurance Systems with Modular Architecture

Modular architecture is enabling innovation in insurance. Insurers are looking at advanced data analytics, machine learning and IoT devices for underwriting and risk assessment. Modular systems makes it easier to integrate these new technologies and personalize policies and proactive risk management.

Blockchain is also on the radar. With modular architecture, smart contracts simplifies claims processing, reduces fraud and enhances security. As regulatory frameworks evolve, modular systems can be updated to meet new requirements.

A Modular Example in Insurance

Decerto’s Agent Portal is a great example of modular architecture in insurance. The portal integrates with existing systems and has customizable software components for policy administration system and claims management. 

It can be implemented incrementally with minimal disruption, and scale as business grows.

Summary

Modular architecture is the way forward for insurers with legacy systems. The flexibility and scalability gives companies the opportunity to modernize, improve customer experience and stay relevant. While moving to modular architecture requires planning the long term benefits far outweigh the short term challenges.

The future of insurance is modular – and it's time to claim your place in it.
