The basics of business rules engines: What are they and how do they work?

Are you tired of constantly making repetitive decisions for your business? Are you looking for a way to automate your decision-making and create more efficient workflows? Look no further than the world of business rules engines!

Business rules engines are computer systems designed to manage and automate your business logic. Think of them as a set of instructions that your computer can follow to ensure your business rules are always enforced. These engines are capable of making complex decisions that would otherwise require human intervention.

In this article, we'll dive into the basics of business rules engines, including what they are, how they work, and some real-world applications.

What is a business rules engine?

At its simplest, a business rules engine (BRE) is a computer program that enables companies to manage and automate their business logic. They enable organizations to define their business rules (also known as business logic or decision rules) in a way that makes it easier to manage and change. Business rules engines are also known as rules engines, decision engines, and rule processing engines.

A BRE enables businesses to capture their business logic and use it to make automated decisions. With a rule engine, you can input data and the engine processes the information according to predefined rules. The engine then outputs the results, which can be used to automate tasks, make informed decisions or provide recommendations.

How do business rules engines work?

Business rules engines work by allowing businesses to define and codify their business logic into a set of rules. These rules are then input to the engine, which processes them based on the data input.

The basic steps of a business rules engine process include:

  1. Data collection: In this step, data is collected from various sources to supply the engine with relevant data points. For example, you might collect data in the format of spreadsheets, databases or other software systems.

  2. Rule creation: Once you've collected your data, you can create rules for your business logic. The rules should adhere to the IF-THEN formatting structure, where you define a condition and how the system should react to it.

  3. Rule Deployment: Once rules are created, they are deployed to the business rules engine. This involves importing the rules into the system and installing them.

  4. Data Processing: With the rules deployed, the system waits for new data to arrive. Once new data arrives, the system applies the rules to process the data. The result is typically an output or action taken based on the decision logic.

  5. Rule Maintenance: Over time, you will need to update or modify your rules to better fit with your evolving business logic. Rule maintenance involves reviewing and updating the rules to ensure they remain relevant.

Advantages of using business rules engines

Now that you understand what a business rules engine is and how it works, let's talk about why you should consider using one for your organization. Here are some of the advantages of using a business rules engine:

  1. Improved decision-making: BREs can process large amounts of data and make decisions based on predefined rules. In doing so, they eliminate the risk of human error and provide fast, reliable insights that can be used to inform important business decisions.

  2. Increased efficiency and productivity: By automating decision-making, you can reduce the time and resources required for making critical decisions. This frees up time and resources to focus on other business activities that may require human intervention.

  3. Easier rule management: Business rules engines make it easier to manage your business logic and make changes as necessary. You can quickly update your rules as your business evolves, ensuring that your decision-making remains accurate and relevant.

  4. Reduced operational costs: With a BRE, you can streamline your workflows and reduce the costs associated with manual decision-making. In some cases, businesses can even reduce the need for dedicated decision-making roles entirely.

Real-world applications of business rules engines

Now that you know what business rules engines are and their advantages, let's take a look at some real-world examples of where they're used:

Insurance industry

Insurance companies rely heavily on rules-based decision-making to determine premiums, underwriting decisions and claims handling. BREs enable insurers to automate these critical business activities, resulting in faster and more accurate processing of customer data. This also allows insurers to reduce the number of staff required to oversee and manage these processes.

Healthcare industry

In the healthcare industry, business rules engines are used to automate decision-making related to patient care. Rules are used to analyze electronic health records (EHRs) and provide care recommendations based on patient data. This can include alerts for drug interactions, diagnoses, and treatment recommendations. In this way, BREs can help reduce medical errors and improve patient outcomes.

Financial services industry

BREs are increasingly used in the financial services industry to automate decision-making processes such as loan approvals, fraud detection, and risk assessments. They enable financial institutions to make faster, more informed decisions based on data, without the need for manual intervention.


In conclusion, business rules engines are powerful tools that can help automate your organization's decision-making processes. Whether you're in insurance, healthcare, finance or any other industry, a BRE can help improve efficiency, reduce costs and provide faster, more informed decision-making.

If you're interested in implementing a business rules engine for your organization, be sure to do your research and choose a solution that aligns with your specific business requirements. With the right solution in place, you'll be well on your way to automating your business logic and achieving greater operational efficiency.
