Customizing Business Rules Engines for Your Industry

A financial institution using the same rule set as a healthcare provider? Sounds ridiculous, right? That’s why customisation is key. By customising Business Rules Engines for your industry you can improve decision making, increase operational efficiency and get ahead of the competition. In this article we’ll get into the world of custom BREs and see how they can transform your business operations.

What are Business Rules Engines

At their heart, a business rule engine is a complex software system that separates business logic from application code. Think of them as the brains behind your business decisions – only much faster and more consistent than human decision makers.

But what makes them tick?

Key Features of Modern BREs:

1. Decision Tables: These are the workhorses of BREs, where complex decision making logic can be represented in a simple table format. It’s like a super powered spreadsheet that can handle your business rules.
2. Rule Management Interfaces: Gone are the days when you needed a Ph.D. in computer science to change business rules. Modern BREs have user friendly interfaces that allow non technical users to manage rules with ease. It’s like giving your business experts a direct line to the decision making process.
3. Integration: A BRE isn’t an island. The best engines integrate with your existing systems, from CRMs to ERPs, so data and decisions flow smoothly across your entire business.
4. Audit Trails: In a world where compliance is king, BREs have audit trails. Every decision, every rule change is logged, so regulators (and your legal team) will love you.

Benefits of Business Rules Engine

Using a BRE isn’t just about keeping up with the Joneses – it’s about turbocharging your business. Here’s how:

1. Better Decision Making: By codifying your business logic, Business Rules Engines make consistent, fast decisions. No more “it depends on who you ask” scenarios.
2. Less Manual Data Entry: Automation is the name of the game. BREs can pull data from multiple sources, reducing manual entry and the errors that come with it.
3. Consistent Rule Application: Whether it’s determining loan eligibility or calculating shipping costs, BREs apply rules consistently across all business processes. It’s like having your most meticulous employee working 24/7 without coffee breaks.
4. Better Customer Experience: Faster decisions mean happier customers. Whether it’s instant approval on a credit card application or real-time insurance quotes, BREs can give your customers the speed they want.

Of course it’s not all good news in the world of BREs. There are obstacles to overcome:

1. Learning Curve: While modern BREs are more user friendly than ever, there’s still a learning curve for non technical users. It’s like learning a new language – hard at first but incredibly powerful once you get it.
2. Balancing Flexibility and Complexity: The power of BREs can be intoxicating. It’s easy to get carried away and create complex rule sets, but this can lead to maintenance hell. The key is finding the sweet spot between flexibility and manageability.

Industry Specific Requirements

When it comes to Business Rules Engines, one size doesn’t fit all. Different industries have different needs, challenges and regulatory landscapes. Let’s break down the key factors that vary by industry and how they impact BRE customization:

Choosing the right Business Rules Management System (BRMS) is crucial for meeting these industry-specific requirements.

Key Factors Varying by Industry:

1. Regulatory Compliance: From HIPAA in healthcare to Basel III in banking, each industry has its own regulatory minefield to navigate. Your BRE needs to be a compliance Swiss Army knife, able to adapt to changing rules.
2. Data Complexity: Some industries have simple structured data. Others have complex unstructured information. Your BRE needs to be able to handle the data thrown at it, whether it’s simple customer info or complex scientific datasets.
3. Decision Making Speed: In high frequency trading, milliseconds matter. In manufacturing quality control, real-time decisions can prevent costly errors. Your BRE needs to match your industry’s speed.
4. User Expertise: Some industries have technical users, others have non technical users. Your BRE’s interface should cater to the expertise level of your team.

Examples of Industry Specific Needs:

1. Financial Services: Risk assessment is the game here. BREs need to handle complex eligibility criteria for loans, insurance policies and investment products. They need to adapt quickly to market changes and new regulations.
2. Healthcare: Treatment protocols and insurance claim processing are critical. BREs in healthcare need to handle complex medical coding, ensure HIPAA compliance and navigate different insurance plans.
3. Manufacturing: Quality control and supply chain optimization are key. BREs need to integrate with IoT devices, handle real-time data from the production line and make split second decisions to maintain product quality.
4. Retail: Pricing strategies and inventory management are important. BREs need to process vast amounts of sales data, competitor information and market trends to optimize pricing and stock levels.

Understanding these industry specific challenges is key. It’s not just about implementing a business rules engine for the sake of it; it’s about implementing the right BRE for your industry. To gather these industry specific requirements consider:

1. Stakeholder Interviews: Talk to the people on the front lines. They know the pain points and opportunities better than anyone.
2. Process Analysis: Map out your current decision making processes. Where are the bottlenecks? Where do errors occur most frequently?
3. Regulatory Review: Stay ahead of the compliance curve by reviewing current and upcoming regulations in your industry.

Remember the goal is to create a BRE that speaks your industry’s language and addresses its challenges.

Customizing Decision Tables and Rules for Specific Industries

Now that we’ve identified industry specific needs, it’s time to get into the details of customization. Customizing decision tables and logical rules is where the rubber meets the road in BRE customization.

Adapting Rule Structures to Industry Terminology

Your BRE should speak your industry’s language. In healthcare it should understand terms like “patient”, “diagnosis” and “treatment”. In finance it should understand concepts like “credit score”, “risk exposure” and “liquidity ratio”. This isn’t just about making your team comfortable; it’s about accuracy and managing business rules effectively.

Industry Specific Rule Templates

Don’t reinvent the wheel for every decision. Create templates that encapsulate common industry specific rules. For example a healthcare BRE might have templates for insurance eligibility checks, a manufacturing BRE could have templates for quality control processes. These templates can significantly streamline the process of executing business rules across various scenarios.

Complex Decision Making Logic

Different industries require different approaches to decision making, and a robust rule engine can handle these complexities:

1. Forward Chaining for Predictive Analysis: This is critical in finance for credit scoring or in retail for demand forecasting. Your BRE starts with available data and works forward to predict outcomes.
2. Backward Chaining for Diagnostic Processes: Essential in healthcare or manufacturing quality control. The BRE starts with a goal (like a diagnosis or a fault) and works backward to determine the cause.

Rule Complexity vs Usability

It’s easy to create very complex rules that cover every possible scenario. Resist this! The key is to find the sweet spot between comprehensive coverage and maintainability. Remember even the most powerful BRE is useless if your team can’t understand or update the rules. A modern business rules engine can help strike the right balance between complexity and usability.

Industry Specific Examples:

‍

Financial Services - Credit Scoring Rules:

IF credit_score > 700 AND annual_income > 50000 AND debt_to_income_ratio < 0.3

THEN credit_risk = "Low"

ELSE IF credit_score > 600 AND annual_income > 30000 AND debt_to_income_ratio < 0.4

THEN credit_risk = "Medium"

ELSE credit_risk = "High"
‍

Healthcare - Treatment Recommendation Rules:

IF diagnosis = "Type 2 Diabetes" AND A1C > 7 AND NOT on_insulin

THEN recommend = "Consider starting Metformin"

ELSE IF diagnosis = "Type 2 Diabetes" AND A1C > 9 AND on_metformin

THEN recommend = "Consider adding insulin therapy"
‍

Manufacturing - Quality Assurance Rules:

IF product_weight < target_weight - tolerance OR product_weight > target_weight + tolerance

THEN quality_status = "Reject"

ELSE IF surface_defects > 0

THEN quality_status = "Inspect"

ELSE quality_status = "Accept"
‍

Retail - Dynamic Pricing Rules:

IF competitor_price < our_price AND stock_level > reorder_point

THEN new_price = competitor_price * 0.95

ELSE IF stock_level < reorder_point

THEN new_price = our_price * 1.1

By industry specific decision tables and rules you’re creating a decision making buddy that understands your business. In the next section we’ll look at how to connect these custom rules to your industry specific data sources.

Industry Specific Data Sources

A Business Rules Engine is only as good as the data it processes. In this section we’ll look at how to connect your custom BRE to your industry data sources.

Data Sources: Every industry has its own data ecosystem. In healthcare you might be working with Electronic Health Records (EHRs) and insurance databases. In finance you could be connecting to credit bureaus and market data feeds. The key is to identify all the data sources that can inform your decision making. Choosing the ideal business rule engine is crucial for seamless data integration and accurate decision-making.

Data Quality and Consistency: Garbage in, garbage out. It’s a cliché but never more true than with BREs. Implement robust data validation rules to catch inconsistencies or errors before they get into your decision making. For example a healthcare BRE might flag impossible age values or conflicting diagnosis codes.

Real-time Data Integration: In many industries decisions need to be made in real-time. Consider these:

1. API Integration: Use RESTful APIs to pull data from external sources on demand.
2. Message Queues: Implement systems like Apache Kafka for high volume real-time data streaming.
3. Change Data Capture (CDC): For database centric systems use CDC to track and respond to data changes in real-time.

Industry Specific Data Formats: From HL7 in healthcare to FIX in finance each industry has its own data standards. Your BRE needs to be able to consume and process these formats. Consider building or buying industry specific connectors to make this easier.

Data Privacy and Security

With great data comes great responsibility. Make sure your BRE complies with industry specific data protection regulations:

• Healthcare: HIPAA compliant data handling and storage.
• Finance: PCI DSS for payment data and GDPR for personal data.
• Retail: Customer data protection in line with consumer protection laws.

Remember a data breach can be catastrophic so encrypt sensitive data in transit and at rest.

By connecting industry specific data sources you’re giving your BRE the fuel to make accurate timely decisions that drive your business.

Customizing BREs

Customizing a Business Rules Engine is not a one and done process. It’s an ongoing journey of refinement and optimization. Here are some best practices to keep your BRE relevant and effective:

Involve Business Users in the Customization: Your IT team might implement the BRE but it’s your business users who really know the business rule. Create a collaborative environment where business experts can contribute their knowledge. This might mean:

1. Regular workshops to review and update rules
2. User friendly interfaces for rule creation and modification
3. Clear documentation of rule rationales

Iterative Development and Testing: Rome wasn’t built in a day and neither is a perfect BRE. Go agile:

1. Start with a Minimum Viable Product (MVP) of core rules
2. Gather feedback from users regularly
3. Implement in small, manageable chunks
4. Test each iteration thoroughly, including regression testing

Industry Specific Training and Documentation: Your BRE is only as good as the people using it. Invest in comprehensive training:

1. Industry specific user guides and tutorials
2. Hands on training sessions
3. Knowledge base of FAQs and best practices

Governance for Rule Management: Without governance your rule base can quickly become a wild west of conflicting or outdated rules. Establish a clear governance structure:

1. Define roles and responsibilities for rule creation, approval and retirement
2. Version control for rules
3. Regularly audit your rule base for conflicts or inefficiencies

Vendor Support for Industry Specific Solutions: Many BRE vendors have industry specific solutions or expertise:

1. Look for vendors with experience in your industry
2. Pre-built rule templates or integrations
3. Vendor training and support services

By following these best practices, you can ensure that your customized BRE remains a valuable asset, continuously evolving to meet your industry’s changing needs.
