The decision

Which architecture patterns deserve further investigation?

This matrix ranks broad solution models against selected constraints. It intentionally stops before vendor selection so the buyer can define acceptance evidence, economic assumptions, integration requirements, and exit rights first.

Input

Budget, volume, site, compliance, latency, analytics, staffing, and legacy constraints.

Output

A model shortlist with fit logic, tradeoffs, and next questions.

Owner

The cross-functional buyer responsible for requirements and acceptance.

Evidence to prepare

Quantify the operating problem before selecting constraints.

  • Sites, devices, event volume, retention, users, and service hours.
  • Current false-positive burden, investigation time, and unresolved incidents.
  • Latency, availability, degraded-operation, and recovery requirements.
  • Privacy, records, cyber, identity, audit, and regulatory constraints.
  • Existing contracts, warranties, integrations, and remaining asset life.
  • Internal engineering, monitoring, support, and change-management capacity.

Working tool

Generate the solution-model shortlist

Select constraints that materially change architecture or delivery risk.

Interpretation

A shortlist is a hypothesis to test.

Use the result to decide which architecture patterns receive a deeper evidence request. Do not treat ordering as a vendor recommendation.

Fit

Which selected constraints does the model address directly?

Tradeoff

What cost, dependency, latency, staffing, privacy, or resilience burden does it add?

Proof

What representative acceptance test would distinguish a claim from capability?

Fallback

How does the system operate during cloud, network, identity, or analytics failure?

Exit

Can data, configuration, evidence, and integrations move to another provider?

Owner

Who accepts each requirement and signs off on exceptions?

Buyer evidence packet

Carry six artifacts into the RFP.

  1. Current-state architecture and data-flow diagram.
  2. Measured event volume, handling time, and false-positive baseline.
  3. Prioritized use cases with prohibited and high-impact decisions.
  4. Acceptance scenarios covering normal, edge, and degraded conditions.
  5. Five-year cost model including integration, support, training, and exit.
  6. Governance record naming approvers, monitoring, review, and stop conditions.

Method and limits

Constraint matching, not market ranking.

The matrix uses deterministic rules to compare broad deployment and delivery patterns. It does not inspect products, prices, contracts, technical designs, vendor viability, or site risk. Validate the shortlist through documented requirements, representative pilots, reference checks, security review, and contract review.
