Material Specification
The engineering-approved definition of materials used in the product — containing material grades, mechanical properties, chemical composition limits, environmental compliance status (RoHS, REACH), approved suppliers, and the test data supporting material qualification for each application.
Why This Object Matters for AI
AI cannot recommend alternative materials, assess supply risk by material type, or validate regulatory compliance without structured material specifications; without them, 'can we substitute this material' requires a materials engineer to manually evaluate property equivalence and compliance impact.

CMC Dimension Scenarios
What each CMC level looks like specifically for Material Specification. Baseline level is highlighted.
Material knowledge lives in the senior materials engineer's head. When someone asks 'what material should I use for this application?' they walk to the materials lab and ask. There are no material specifications written down. Part drawings say 'steel' or 'aluminum' without grade, temper, or property requirements. When the materials expert retires, decades of material selection knowledge walk out the door.
AI cannot perform material selection, compliance checking, or property analysis because no material specifications exist in any documented form.
Create material specifications for active materials — at minimum, document the material grade, key mechanical properties, and the standards each material must conform to.
Material specifications exist as entries on part drawings or in individual engineers' reference files. Some engineers maintain personal material databases in Excel. Material callouts on drawings vary — one drawing specifies 'AISI 304 per ASTM A240,' another says '304 SS.' Approved supplier lists and qualification test data are maintained separately, if at all. Finding the complete material specification for a component requires checking the drawing, the engineer's files, and the supplier quality folder.
AI could parse drawings and documents to extract material references but cannot reliably compile complete material specifications because callout formats vary and supporting data (test results, compliance status) is scattered.
Standardize a material specification template with required fields — material grade, standard reference, mechanical properties, chemical composition limits, environmental compliance status, and approved sources.
A standard material specification template is used for all qualified materials. Each spec has a defined format — material grade, referenced standards, mechanical property requirements, chemical composition limits, environmental compliance (RoHS, REACH status), and approved suppliers. Specs are stored in a shared location organized by material family. Engineers can find the spec for any qualified material. But application-specific requirements (this material for this part in this environment) are documented separately or not at all.
AI can search and compare material specifications, identify materials by property requirements, and generate material compliance reports. Cannot perform application-specific material selection because usage context and environmental exposure data is not linked to material specs.
Implement a material management system that links material specifications to their applications (which parts use them, in what environments, with what performance requirements) and to qualification test data.
Material specifications are managed in a structured system with formal links to applications, qualification test data, and supplier quality records. Each material links to the parts that use it, the environments those parts operate in, and the qualification testing that validated the material for each application. An engineer can query 'show me all materials qualified for high-temperature applications above 200°C with RoHS compliance' and get a reliable, complete answer.
AI can perform automated material selection based on application requirements, predict material performance in specified environments, and assess supply risk by material type. Can identify material standardization opportunities across the product portfolio.
Implement schema-driven material specifications with formal property ontologies, machine-readable compliance mappings, and API-accessible qualification evidence that AI agents can query and reason over programmatically.
Material specifications are schema-driven entities with formal property ontologies. Material properties are machine-readable with units, test methods, and statistical distributions. Compliance mappings link each material to every applicable regulation with current status and evidence. Qualification data links to test records with full traceability. An AI agent can answer 'can I substitute Material A for Material B in this application considering mechanical, thermal, chemical, and regulatory constraints?' with a comprehensive, quantified assessment.
AI can perform fully autonomous material selection, compliance assessment, and substitution analysis. Predictive material performance models enable virtual qualification for parameter variations. Multi-objective material optimization (cost, performance, supply risk, compliance) is comprehensive.
Implement real-time material intelligence streaming where supplier certifications, regulatory updates, and property data from ongoing testing publish as structured events continuously.
Material specifications are living documents that continuously evolve. Supplier test certificates auto-update property data. Regulatory database subscriptions maintain current compliance status. Ongoing material testing feeds back refined property distributions. The specification reflects the current state of material knowledge from all sources in real-time. There is no static 'material spec' — only a continuous material intelligence stream.
Fully autonomous material lifecycle management. AI maintains the complete material knowledge base in real-time, selecting, qualifying, and monitoring materials across the product portfolio without manual specification maintenance.

CAD Model and Design File
EntityThe digital product definition maintained in CAD systems — 3D models, 2D drawings, assemblies, geometric dimensions and tolerances (GD&T), revision history, and the parametric relationships that define how design features interact and constrain each other.
Engineering Bill of Materials (EBOM)
EntityThe engineering-owned product structure defining components, sub-assemblies, and materials from a design perspective — including part numbers, revision levels, material specifications, make-versus-buy designations, and the effectivity dates that track which configuration is current.
Design Requirement Specification
EntityThe structured set of functional, performance, regulatory, and customer requirements that the product design must satisfy — including requirement IDs, acceptance criteria, priority, verification method, traceability links to test cases, and compliance status maintained through the development lifecycle.
Engineering Change Order
EntityThe formal record documenting a proposed or approved change to a product design — containing the change description, affected parts, reason for change, impact assessment (cost, schedule, tooling, inventory), approval signatures, and implementation status across engineering, manufacturing, and supply chain.
Test and Validation Record
EntityThe structured record of product testing activities and results — containing test plans, test procedures, pass/fail outcomes, measurement data, environmental conditions, traceability to requirements, and the engineering judgment on whether results support design release.
Field Performance Feedback Record
EntityThe structured collection of product performance data from the field — warranty claims, failure analysis reports, customer usage patterns, reliability metrics (MTBF, failure rates), and environmental exposure data fed back to engineering to inform design improvements and validate reliability models.
Design Release Decision
DecisionThe stage-gate judgment point where engineering leadership evaluates whether a design is ready to release to manufacturing — assessing requirements coverage, test completion status, DFM compliance, risk items, and the evidence package required to authorize the transition from development to production.
Engineering Change Approval Decision
DecisionThe recurring judgment point where a change review board evaluates whether to approve, defer, or reject an engineering change — weighing technical merit, cost impact, schedule impact, inventory disposition, customer notification requirements, and regulatory re-certification needs against the benefit of the change.
