How to Choose a Rules Engine: 9-Criteria Checklist (2026)

The BRMS RFP that arrives on a CTO's desk and three months disappear

Last quarter Sarah, the CTO at a $1.8B GWP P&C carrier in the Southeast, forwarded me an internal email from her VP of Engineering. The subject line: "BRMS Vendor Selection - Need Decision by End of Q3." Inside: nine vendor pitches her team had collected, three demos already completed, two more scheduled, and a 47-page RFP document her enterprise architect had circulated for vendor responses. Her question to me was simple: "How do other mid-market carriers actually decide between these? Because right now my team has spent six weeks and we are no closer to a recommendation than when we started."

In my experience, this scene plays out at most mid-market insurance carriers and banks every 18-24 months when current decision systems strain past their limits. The BRMS evaluation starts well - clear pain point, executive sponsor, budget approved. By week six the team has accumulated more vendor information than they can synthesize and the original decision criteria have blurred into vendor-feature checklists. The PoC scope creeps. The decision drags. Someone on the executive committee eventually asks the question that resets the whole evaluation: "What are we actually buying here?"

This article is the buying methodology I use with carriers going through BRMS evaluation. Nine criteria that matter at mid-market scale (not the 47 features vendor pitch decks list), a PoC framework that surfaces what vendor demos hide, an RFP question template that gets concrete responses, common mistakes I see during evaluation, and the decision matrix that produces a defensible recommendation in 4-8 weeks rather than 4-8 months. The framing is Sarah-CTO RFP-stage and Daniel-architect technical evaluation-stage at mid-market $500M-$5B GWP P&C carriers and $1B-$20B AUM banks.

Save this for your buying committee:

The 9-criterion checklist in Section 3 plus the RFP template in Section 6 are also bundled with concrete vendor scorecards in our BRE Comparison Guide - 12 vendors (Drools, Camunda, FICO Blaze, InRule, IBM ODM, Higson, Easy Rules, OpenL Tablets, Sparkling Logic, Sapiens, Pega, Red Hat Decision Manager) compared across 25 criteria in a 45-page downloadable PDF. The article gives you the methodology; the guide gives you the comparison data to apply it.

How do you choose a business rules engine?

Mid-market insurance and banking BRMS selection comes down to nine criteria evaluated through a structured PoC and RFP process. The criteria:

(1) insurance or banking domain fit;

(2) performance characteristics under your actual load profile;

(3) integration capabilities with your existing stack;

(4) no-code authoring fit for your Business Analysts;

(5) vendor stability and roadmap;

(6) total cost of ownership at year 5;

(7) security and compliance posture (SOC 2, CREST, NAIC);

(8) deployment options (cloud, on-prem, hybrid);

(9) innovation roadmap covering AI integration, ONNX, MCP.

The selection process: 2-week requirements gathering, 4-6 week parallel PoC with 2-3 shortlisted vendors using representative rule set and load profile, 2-week scoring and decision matrix completion, total 8-12 weeks elapsed. Mid-market evaluations typically narrow from 8-12 initial vendors to 2-3 PoC finalists to 1 selected vendor. The article walks each criterion in detail and provides the RFP question template, PoC framework, and decision matrix template that the buying committee uses.

The 9-criterion BRMS buying checklist

This is the checklist I run with carriers during BRMS evaluation. In my experience, each criterion has a why-it-matters paragraph, the question to ask vendors, and a mid-market-specific calibration. The checklist explicitly excludes 30+ features vendor pitch decks include but mid-market evaluations rarely need - exclusion is part of the methodology.

Criterion 1: Domain fit - insurance-native or generic

BRMS vendors split into two categories: insurance/banking-native (Higson, FICO Blaze Advisor for credit decisioning, Sapiens DECISION, Sollers Consulting platforms) and generic horizontal (Drools, Camunda, IBM ODM, Pega Decision Hub, InRule, Sparkling Logic). Insurance-native vendors arrive with domain features built in (state-by-state regulatory templates, ACORD data model alignment, rating factor patterns, NAIC compliance templates); generic vendors require carrier teams to build these from scratch.

Question to ask: How many insurance carriers do you have in production, what lines of business, and can you walk me through a current customer's pricing rule library?

Mid-market calibration: 200+ insurance implementations (Higson, FICO) signals domain fit; 0-5 carrier customers indicates the vendor is generic-with-insurance-marketing. Both can work but the integration effort differs by 6-12 months.

Criterion 2: Performance characteristics under your actual load profile

Vendor pitch decks quote "up to N req/s" without context. Mid-market production sustained throughput depends on rule complexity, request payload, integration topology, and hardware sizing. Concrete benchmarks matter: Higson Runtime REST 0.23 ms P50 / 1.5-2.1 ms P99 at 9 000 req/s sustained; Drools at default configuration 5-20 ms P50 / 50-200 ms P99 at 1 000-3 000 req/s; enterprise BRMS (IBM ODM, FICO Blaze) scale higher at enterprise pricing.

Question to ask: Run a load test against my representative rule set (year-3 estimated size) with my actual JSON payload at my expected sustained throughput. Show me P50 and P99 latency plus memory footprint.

Mid-market calibration: insurance carriers typically need 2 000-5 000 req/s sustained at sub-5 ms P50 for real-time quoting; banking 5 000-10 000 req/s sustained. Run the PoC at production scale - vendor demos at 50 rules and 100 req/s reveal nothing useful about production behavior.

Criterion 3: Integration capabilities with your existing stack

Modern BRMS expose REST API, Java SDK, batch processing interfaces, and event-streaming integration. Older vendors (some Drools deployments, IBM ODM legacy) sometimes require .NET-specific integration or SOAP-era patterns. Mid-market carriers with polyglot stacks (Java + Python + .NET microservices) need REST as the lingua franca; Java-end-to-end shops benefit from embedded SDK for the latency hop.

Question to ask: Show me the integration documentation for REST API + Java SDK + batch processing + event-driven consumption. Include code samples for Spring Boot, .NET, and message bus integration if any of those are in our stack.

Mid-market calibration: REST API + Java SDK + batch is table stakes in 2026. Vendors that emphasize one to the exclusion of others (typically older platforms) signal future integration friction. Newer integration patterns - MCP server for AI agent integration, ONNX for ML model serving - are differentiators rather than table stakes.

Criterion 4: No-code authoring fit for your Business Analysts

The Linda BA persona is who uses the authoring tool daily. Vendors with weak authoring tools shift workload to engineering (Drools Workbench is engineer-oriented; Easy Rules has no authoring tool at all - rules live in Java code). Vendors with strong authoring tools (Higson Studio, irAuthor from InRule, FICO Decision Manager Studio, IBM Decision Center) let BAs author rules directly. The authoring tool determines whether BRMS adoption succeeds operationally - if Linda cannot author rules without engineering help, the 24-72 hour rule-change cycle promise does not materialize.

Question to ask: Have a BA on my team author a representative rule in your studio during the PoC. Not a vendor demo of someone else doing it - my BA, with no prior training, doing the work.

Mid-market calibration: 30-60 minutes for a BA to author a moderately complex pricing rule (8-12 conditions) without help is the realistic target. More than 2 hours signals authoring friction that will dominate operational cost. Less than 15 minutes is suspicious - probably the rule was too simple for the test.

Criterion 5: Vendor stability and roadmap

Daniel-architect lèk #2: "vendor disappears or pivots after we standardize." Recent industry pattern: FICO acquired by Thoma Bravo in 2022 (private equity); InRule licensing model changes annually; Drools is part of Red Hat / IBM after acquisition. Newer vendors (Sparkling Logic, Sollers) are smaller but stable. Mid-market evaluations should weight vendor stability heavily because BRMS is a 5-10 year commitment.

Question to ask: Share your last 3 years of release cadence, customer count and retention numbers, financial backing, and product roadmap for the next 12-24 months.

Mid-market calibration: 20+ year-old vendors with consistent release cadence (Higson via Decerto since 2005, FICO Blaze since 1990s, IBM ODM since 2010s) signal stability. Vendors with frequent licensing model changes or unclear ownership signal future surprise. Healthy private companies are often more stable than public-company BRMS divisions because the latter are subject to quarterly earnings pressure.

Criterion 6: Total cost of ownership at year 5

License cost is one component of BRMS TCO. The honest model: year-1 includes license + implementation services ($150K-$500K typical); year-2-5 includes annual license + maintenance + specialist engineering time. Open-source BRMS (Drools) has $0 license but typical 5-year mid-market TCO is $2.5M-$4M including 2 senior Java engineers maintaining the deployment. Proprietary mid-market BRMS (Higson, InRule, Sparkling Logic) typically $500K-$1.7M 5-year TCO including license, implementation, and reduced engineering specialist need.

Question to ask: Provide a 5-year TCO breakdown including license, implementation services, maintenance, specialist engineering FTE recommendations, training, and infrastructure costs at our expected scale.

Mid-market calibration: Total 5-year TCO at mid-market scale typically lands between $500K (lightweight proprietary) and $4M (enterprise tier or open source with engineering overhead). The detailed TCO breakdown including hidden costs is in our BRMS Pricing Models article and the BRE Comparison Guide downloadable below.

Criterion 7: Security and compliance posture

Mid-market carriers and banks face increasing security requirements: SOC 2 Type II attestation, CREST certification for penetration testing, NAIC compliance for AI/ML systems, state-specific data security requirements (NY DFS, California, Colorado). Vendor security posture matters because BRMS sits inside the regulated decision path - audit findings against the BRMS vendor become findings against the carrier.

Question to ask: Provide current SOC 2 Type II report, penetration test results from the last 12 months, NAIC AI Bulletin compliance approach, and your data security posture for customer data passing through rule evaluation.

Mid-market calibration: SOC 2 Type II + CREST + NAIC awareness is the minimum bar in 2026. Vendors without current SOC 2 attestation should be deprioritized; the audit cycle to obtain it takes 9-12 months and is not something to start during your BRMS evaluation.

Criterion 8: Deployment options (cloud, on-prem, hybrid)

Mid-market carriers split roughly 60/40 cloud-first vs hybrid-cloud (some on-prem retention for regulated data). BRMS deployment flexibility matters: pure cloud-only vendors do not fit carriers with on-prem requirements; on-prem-only vendors do not fit cloud-first IT strategies. AWS Marketplace presence indicates cloud-native posture; Helm chart and Kubernetes manifests indicate modern operations support.

Question to ask: List all supported deployment options - AWS, Azure, GCP, Kubernetes, on-prem, hybrid. Include AWS Marketplace presence, Helm charts, Terraform modules. Show me a current customer running your platform in our target deployment mode.

Mid-market calibration: AWS Marketplace + Kubernetes + Helm + Docker images are 2026 baseline expectations. Vendors without these signal operational friction. AWS Marketplace at consumption pricing (Higson at $0.63/hour) signals modern commercial posture and lets technical evaluators run their own PoC without procurement involvement.

Criterion 9: Innovation roadmap - AI integration, ONNX, MCP

BRMS market is evolving toward hybrid AI patterns - rules + ML models inside a single audit trail. Vendors with ONNX runtime native support (Higson) implement this pattern natively; vendors that require custom integration code (Drools, IBM ODM) make the pattern an engineering project. MCP server support for AI agent integration (Higson is one of the few BRMS vendors with this) is a 2026+ differentiator that signals vendor investment in emerging integration patterns.

Question to ask: Show me how your platform supports ONNX models inside rule evaluation, what your AI/ML integration story is, and whether you have MCP server support or roadmap. Run an end-to-end example with a sample ONNX model.

Mid-market calibration: ONNX native support is a 2026 buying-cycle differentiator. Vendors without it can still serve current needs but will require custom integration for hybrid AI patterns. MCP server support is a 2026+ early indicator of vendor innovation investment. Neither is required for traditional rules-only deployments but both matter for 5-year horizon.

The PoC framework: 4-week parallel evaluation

Vendor demos look great. Vendor PoCs at PoC-team scale (50 rules, 100 req/s) prove nothing about production behavior. In my experience, the PoC framework I run with carriers is structured to surface what demos hide while staying time-bounded enough that the evaluation actually finishes.

Week 1: Requirements crystallization

Carrier team produces a representative rule set (200-500 rules covering 3-5 realistic decision tables), representative JSON request payload (actual production field count), expected sustained throughput target, latency SLO, and integration topology. This input goes to all 2-3 shortlisted vendors simultaneously. The discipline matters: vendors that get the same input produce comparable outputs; vendors that get different inputs produce incomparable results.

Week 2-3: Parallel vendor PoC

Each vendor implements the rule set in their platform, integrates with the carrier's test environment, and runs the sustained load test. Carrier team observes: ease of rule authoring (BA test from Criterion 4), engineering integration effort, deployment friction, support responsiveness. PoCs run in parallel to enable comparison; sequential PoCs create recency bias toward the last vendor seen.

Week 4: Scoring and decision matrix

Carrier team scores each vendor against the 9 criteria using the decision matrix template in Section 7. Buying committee meets to review the matrix, discuss scoring rationale, and produce the recommendation. The matrix is the artifact: when the CFO asks why this vendor was selected, the matrix answers in writing, signed by the buying committee.

Total elapsed: 4 weeks for the evaluation phase. Plus 2 weeks requirements gathering before and 2 weeks contract negotiation after, the full BRMS selection process runs 8-12 weeks. Carriers running 4-6 month evaluations are doing it inefficiently; carriers running 2-week evaluations are doing it shallowly. I recommend the 8-12 week timeline as the sweet spot - long enough to produce defensible, well-scoped selections, short enough that the buying committee maintains focus.

Five common BRMS evaluation mistakes (and how to avoid them)

Mistakes I see consistently across mid-market BRMS evaluations. In my experience, none is fatal individually; combinations of them produce 6-12 month evaluations that produce regrettable choices.

Mistake 1: Evaluating too many vendors

Carriers that invite 8-12 vendors to formal PoC produce 6+ month evaluations with low-quality output. The decision overhead exceeds the comparison value. The fix: filter to 2-3 vendors via paper RFP and reference calls before any PoC starts. The shortlist criteria - domain fit (Criterion 1), TCO range (Criterion 6), and current customer count - eliminate 60-70% of candidates before serious technical evaluation begins. Carriers running 2-3 vendor parallel PoCs make better decisions in 4 weeks than carriers running 8-vendor sequential PoCs make in 6 months.

Mistake 2: PoC at demo scale instead of production scale

Vendor PoCs are typically designed by vendors and feature small rule sets and modest load. The output - "all 3 vendors handled it fine" - tells the carrier nothing. The fix: carrier team designs PoC scope with representative rule set, representative payload, sustained load test, and burst testing. This is the difference between PoCs that surface production behavior and PoCs that demo vendor enthusiasm.

Mistake 3: Optimizing for features rather than total cost

RFP feature checklists become 100+ items long. Vendors that check the most boxes appear strongest. The fix: weight the 9 criteria explicitly in the decision matrix - TCO at year 5 (Criterion 6) often weights 25-30% of the total score; features that look impressive in demos but do not move TCO or production performance get weighted at 2-5%. Feature lists rarely produce different vendor rankings; weighted criteria reliably do.

Mistake 4: Skipping the BA authoring test

Procurement teams evaluate technology with technologists. Daniel and Sarah dominate the room; Linda the BA is occasionally consulted. The fix: Criterion 4 testing is non-negotiable. Have an actual BA on your team author a representative rule during each PoC, with you observing and timing. The BA authoring friction is the single biggest predictor of long-term operational satisfaction with the BRMS; skipping this test is how carriers end up with technically-impressive platforms that nobody can operate.

Mistake 5: No paradox-of-transparency vendor questions

Vendors do not volunteer their fit limitations. Sales decks are universally optimistic. The fix: ask each vendor explicitly "when is your platform the wrong choice?" Honest vendors answer with specifics (Higson is not the right answer for 50 000+ req/s enterprise scale; InRule wins .NET-end-to-end shops; Drools wins for teams with deep Java specialist staffing). Vendors that cannot answer this question reveal they have not thought carefully about their fit profile - which is itself information about future surprise during deployment.

RFP question template: 8 questions that get concrete answers

The 8 questions I include in every BRMS RFP I help carriers run. Each is designed to surface specific, comparable information rather than vendor-marketing prose.

1. Domain fit and references. How many insurance carriers do you have in production, what lines of business, average GWP size? Can you connect me with 2 current customers in my GWP range for a reference call?

2. Performance benchmark. Run a sustained load test against the attached rule set (200-500 representative rules) using the attached JSON payload format. Report P50 / P95 / P99 latency at our target throughput, plus memory footprint at production rule count. Attach raw load-test data.

3. BA authoring test. Have one of your customer success engineers train one of my BAs on your studio for 30 minutes. The BA then authors a representative 10-condition pricing rule. Time the entire exercise. Provide the recording.

4. Integration depth. Provide working code samples for: REST API consumption from Java/Spring Boot, REST API consumption from .NET, embedded Java SDK initialization, batch processing entry point, event-driven invocation via Kafka or similar. Include OpenAPI specification.

5. 5-year TCO. Provide a year-by-year cost breakdown including license, implementation services, annual maintenance, training, specialist engineering FTE recommendations, and infrastructure. Use our scale assumptions (X rules, Y req/s sustained, Z analyst seats).

6. Security and compliance. Provide current SOC 2 Type II report. Provide penetration test results from last 12 months. Describe your NAIC AI Bulletin compliance approach. Describe your data security posture for customer data passing through rule evaluation.

7. Deployment flexibility. List all supported deployment options with specific tooling (Helm charts, Terraform modules, AWS CloudFormation, on-prem installer). Demonstrate AWS Marketplace consumption pricing if available. Reference at least one customer running in our preferred deployment mode.

8. Innovation roadmap and fit limitations. Describe your product roadmap for the next 12-24 months covering AI integration, ONNX support, MCP server, agent integration. Then describe explicitly when your platform is NOT the right choice - what carrier profile, scale, or use case is better served by your competitors.

Two things this RFP template does well that most vendor-supplied RFP templates do poorly. First, every question requires concrete artifacts (load-test data, code samples, TCO breakdown, SOC 2 report) rather than narrative answers. Second, Question 8 explicitly asks vendors to disqualify themselves - which separates vendors with honest fit assessment from vendors with universal sales decks.

The BRMS decision matrix: scoring across 9 criteria

The decision matrix is the artifact your buying committee uses to make the final selection and the CFO sees as justification. In my experience, the template below is what I recommend carriers use - 9 criteria with explicit weights, scored 1-5 per vendor, weighted total produces the recommendation.

Weights above are my default recommendation for mid-market insurance carriers; adjust based on your specific priorities. For example, banking carriers often weight Criterion 7 (security/compliance) higher at 15% and Criterion 1 (insurance domain fit) lower at 5%. Carriers with strong existing engineering teams sometimes weight Criterion 6 (TCO) lower because they can absorb specialist engineering cost. The discipline is to set weights before scoring - retrofitting weights to justify a chosen vendor is the most common way evaluations produce regrettable selections.

The BRE Comparison Guide: 12 vendors scored across 25 criteria

The 9-criterion checklist above is the methodology. To apply it concretely to vendors, you need the comparison data. Our BRE Comparison Guide is the downloadable resource carriers reference during evaluation - 12 vendors compared across 25 evaluation criteria with concrete scores, pricing ranges, and reference customer profiles.

What is in the BRE Comparison Guide:

• 12 vendors scored: Drools, Camunda, FICO Blaze Advisor, InRule, IBM ODM, Higson, Easy Rules, OpenL Tablets, Sparkling Logic, Sapiens DECISION, Pega Decision Hub, Red Hat Decision Manager

• 25 evaluation criteria across domain fit, performance, integration, authoring, vendor stability, TCO, security, deployment, and innovation

• Concrete pricing ranges per vendor (license, implementation, 5-year TCO)

• Reference customer profiles for each vendor (industry, scale, deployment type)

• Honest fit assessment per vendor (when it wins, when it loses)

• 45 pages, designed for buying committee circulation

• Updated quarterly with vendor release tracking

DOWNLOAD: BRE Comparison Guide 2026 - 12 vendors scored across 25 criteria, 45 pages. Free download at /business-rules-engine-comparison. Updated quarterly. Designed specifically for mid-market insurance carrier and bank buying committees applying the 9-criterion methodology in this article.

The guide pairs with this article: the article gives you the methodology (9 criteria + PoC framework + RFP template + decision matrix); the guide gives you the vendor data to apply it. Carriers running serious BRMS evaluations typically download the guide during requirements crystallization (Section 4, Week 1) and reference it throughout the evaluation.

When this methodology does not fit your evaluation

I would rather lose a deal than win one badly. Three scenarios where the 9-criterion methodology is overkill or misaligned:

• Sub-100-rule decision systems with no Business Analyst authoring requirement. If your scale and complexity do not justify a BRMS investment at all (covered in our Building Your Own Rules Engine and BRE vs DE articles), running an 8-week evaluation produces overhead without value. Document rules in code with good tests, move on. BRMS evaluation methodology earns its complexity at 500+ rules and quarterly-or-faster change velocity.

• Replacement-in-place evaluations where the incumbent is known. If your current BRMS is failing and you have already decided to migrate, the question is which alternative to migrate to - not whether BRMS adoption is the right pattern. A focused 2-3 vendor PoC with sharper criteria weighting toward migration friction (data export, rule format translation, parallel-run support) fits better than a full 9-criterion evaluation against your incumbent.

• Single-criterion-dominant evaluations. Carriers with hard constraints that eliminate most vendors (".NET-end-to-end shop" eliminates non-.NET-native; "50 000+ req/s sustained" eliminates mid-market vendors; "on-prem only" eliminates cloud-first vendors) sometimes converge on 1-2 vendors before formal evaluation. Spending 8 weeks evaluating against criteria the constraints already settled is wasted process. Run a shorter focused PoC against the surviving 1-2 vendors.

Within mid-market insurance carriers and banks with 1 000+ active rules and modern integration requirements, the 9-criterion methodology produces evaluations that survive board-level scrutiny and deliver platforms the team operates successfully for 5+ years. Outside that profile, scale the methodology to the decision size.

FAQ

How do you choose a business rules engine?

Mid-market insurance and banking BRMS selection comes down to 9 criteria evaluated through structured PoC and RFP: domain fit (insurance-native vs generic), performance under actual load, integration capabilities, no-code BA authoring fit, vendor stability, 5-year TCO, security/compliance posture, deployment flexibility, innovation roadmap (AI/ONNX/MCP). Process: 2 weeks requirements crystallization, 4-week parallel PoC with 2-3 shortlisted vendors using representative rule set and load profile, 2 weeks scoring and decision matrix. Total 8-12 weeks elapsed.

What are the criteria for selecting a rules engine?

Nine criteria with recommended weights for mid-market evaluations: domain fit 15%, performance 15%, integration 10%, BA authoring 15%, vendor stability 10%, 5-year TCO 15%, security/compliance 10%, deployment flexibility 5%, innovation roadmap 5%. Banking carriers typically weight security higher (15%) and domain fit lower (5%). Set weights before scoring - retrofitting weights to justify a chosen vendor is the most common evaluation mistake.

How long should a BRMS evaluation take?

Well-run mid-market BRMS evaluations take 8-12 weeks elapsed: 2 weeks requirements crystallization, 4-week parallel PoC with 2-3 shortlisted vendors, 2 weeks scoring and decision matrix completion, 2 weeks contract negotiation. Carriers running 4-6 month evaluations are evaluating too many vendors or running sequential PoCs (recency bias). Carriers running 2-week evaluations skip the BA authoring test and production-scale PoC, producing regrettable selections.

How many vendors should you invite to a BRMS PoC?

2-3 shortlisted vendors for parallel PoC. Filter from 8-12 initial candidates via paper RFP and reference calls before any PoC starts. Shortlist criteria - domain fit, TCO range, customer count - eliminate 60-70% of candidates before serious technical evaluation. Carriers running 2-3 vendor parallel PoCs make better decisions in 4 weeks than carriers running 8-vendor sequential PoCs in 6 months. The decision overhead at 8+ vendors exceeds the comparison value.

What questions should I ask BRMS vendors in an RFP?

Eight questions: (1) domain fit + 2 reference customers, (2) performance load test against your representative rule set with raw data, (3) BA authoring test with your actual BA, (4) integration code samples for REST + Java SDK + .NET + batch + events, (5) 5-year TCO breakdown including specialist FTE recommendations, (6) current SOC 2 Type II + pen test + NAIC compliance approach, (7) all deployment options with specific tooling, (8) innovation roadmap + explicit statement of when your platform is NOT the right choice. Question 8 separates honest vendors from universal sales decks.

What is the difference between a BRMS comparison and a buying guide?

A BRMS comparison ranks vendors on standard criteria (typically G2, Capterra, or analyst-style scorecards). A buying guide provides the methodology for applying comparison data to your specific evaluation. The 9-criterion checklist + 4-week PoC framework + RFP template + decision matrix in this article is the buying methodology; the Higson BRE Comparison Guide at /business-rules-engine-comparison is the 12-vendor 45-page comparison data. Carriers use both: methodology for process, comparison data for vendor scoring.

What is the most common BRMS evaluation mistake?

Evaluating too many vendors in formal PoC (8-12 invited, 6+ month evaluation, low-quality output). The fix: filter to 2-3 vendors via paper RFP before PoC, using domain fit + TCO range + customer count as shortlist criteria. Other common mistakes: PoC at demo scale instead of production scale, optimizing for feature checklist length rather than weighted criteria, skipping the BA authoring test, and not asking vendors when their platform is NOT the right choice.

Can I evaluate a rules engine without involving IT?

Probably not. BRMS evaluation requires Sarah CTO (strategic ownership, TCO sign-off), Daniel architect (integration, security, deployment), and Linda BA (no-code authoring test from Criterion 4). Procurement-led evaluations that skip Daniel produce technical surprises during implementation; technology-led evaluations that skip Linda produce platforms BAs cannot operate. The buying committee is cross-functional - CTO + Enterprise Architect + Lead BA + Compliance/Risk if applicable - because BRMS impacts all of those functions over the 5-10 year deployment lifetime.

Talk to Higson

BRMS evaluation is a 5-10 year commitment compressed into 8-12 weeks of decision-making. The carriers who get this right have a structured methodology, the time to apply it, and the discipline to filter from many vendors to 2-3 finalists before PoC starts. The 9-criterion checklist plus PoC framework plus RFP template in this article is what I run with carriers; the BRE Comparison Guide gives you the vendor data to apply it concretely.

Higson is built for mid-market insurance carriers $500M-$5B GWP, mid-market banks $1B-$20B AUM, and mid-size healthcare payers. We score well against Criterion 1 (insurance-native, 200+ insurance implementations via Decerto), Criterion 2 (0.23 ms P50 / 9 000 req/s), Criterion 4 (Higson Studio no-code authoring designed for BAs), and Criterion 9 (native ONNX runtime + MCP server). We are not the right answer for enterprise scale 50 000+ req/s sustained throughput (InRule and IBM ODM enterprise tiers fit better), .NET-end-to-end shops (InRule wins), pure ML decision systems (TensorFlow Serving fits better), or sub-100-rule deployments (BRMS overhead does not pay back). The honest fit boundaries are what Criterion 1 + Criterion 2 + Criterion 6 are designed to surface in evaluation.

If you would like to apply the methodology with Higson included in your evaluation - or just talk through which criteria matter most for your specific scenario - I would be happy to walk through it with your buying committee.

Three ways to start:

• Download the BRE Comparison Guide - 12 vendors compared across 25 criteria, PDF for buying committee circulation. THE primary resource for applying this methodology.

• Try Higson on AWS Marketplace at $0.63 / hour - 15 minutes from subscription to first decision execution. Run your own Criterion 2 performance test without procurement involvement.

• Schedule a 30-minute methodology review - we will walk through your specific evaluation context, criteria weighting recommendations, and PoC scoping for your environment.
