Screening Insurance Eligibility by Age and Region with BLOCK Rules
Age, state, and coverage screens move out of scattered conditionals into BLOCK rules, so every decline carries its reason.
Feature Entitlement & Plan Limits: Stop Hardcoding Your Pricing Tiers
Plan tiers hardcoded across services turn every pricing change into a deploy. Feature flags are the wrong home for entitlement — and a new plan tier should be a rule change, not a deploy.
What Is a Decision Operations Platform? (And When Your Team Needs One)
Pricing, eligibility, and fraud rules change constantly but live trapped in application code. A Decision Operations Platform gives business decisions their own lifecycle. What the category is, and when you need one.
Centralizing Plan-Tier Feature Entitlement with BLOCK Rules
Per-tier feature checks move out of scattered conditionals into BLOCK rules, so every denied feature carries its reason.
Adjudicating Credit Applications with a Priority-Ordered Mutex Group
A pattern that routes each credit application to one of approve, decline, or refer, and records which rule produced the decision.
Rule Engine for E-Commerce: Discounts, Promotions, and Eligibility
E-commerce discounts, promotions, and eligibility multiply faster than any other logic — and break in checkout code. Where these rules should live, why the hardcoded version fails, and how to ship promotions without margin surprises.
Enforcing KYC-Tiered Transfer Limits with BLOCK Rules
Per-KYC-level transfer limits move out of scattered constants into BLOCK rules, so every blocked transfer carries its reason.
Testing a Rule Change Before Deploy with Impact Simulation
Measure a rule change's full impact against real historical orders before production, then decide on that evidence whether to ship.
Config Files, Feature Flags, or Something Else? Managing Business Logic at Scale
Where business logic should live as it grows — config files, feature flags, a database rules table, or a managed decision platform — and when each one stops fitting.
Resolving VIP Tier Discount Stacking with a Mutex Group
A pattern that guarantees exactly one discount applies when tier discounts and seasonal campaigns collide.
Your If-Else Pricing Logic Will Break. Here's What to Do Before It Does.
Refactoring your pricing if-else block doesn't fix the underlying problem. The structural answer is rules-as-data plus simulation — not better class hierarchies.
Drools vs Cloud Rule Engines: Self-Hosted vs Managed in 2026
Drools is the open-source default — but the README doesn't mention what self-hosting actually costs. Here's how Drools, GoRules, DecisionRules.io, Camunda, and LexQ compare in 2026.
Hardcoded Rules vs Rule Engine: When to Make the Switch
Your if-else blocks are working fine — until they aren't. Here's how to tell when hardcoded business rules become a liability, and what the migration path looks like.
5 Signs Your Team Needs a Rule Engine
Not every team needs a rule engine. But if you recognize these patterns, you're probably overdue for one.
Managing Business Rules with AI Agents: What MCP Changes
AI agents can now create, test, and deploy business rules autonomously. Here's how the Model Context Protocol(MCP) makes it possible — and why it matters for engineering teams.
GoRules vs Nected vs LexQ: Choosing the Right Rule Engine in 2026
A practical comparison of three modern rule engines — architecture, simulation, pricing, and AI integration. No fluff, just what matters for your decision.
Why I Built a Rule Engine with Built-in Simulation
Every rule change is a leap of faith. I spent 6 years watching teams deploy blind — so I built a rule engine where you can see the impact before it hits production.
