Design Requirement Specification
The 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.
Why This Object Matters for AI
AI cannot automate requirements traceability, generate test plans, or extract customer needs from voice-of-customer data without a structured requirements database; without it, 'does this design meet all requirements' requires manual cross-checking between specification documents and test results.

Typical CMC levels for product engineering & development in Manufacturing organizations.
CMC Dimension Scenarios
What each CMC level looks like specifically for Design Requirement Specification. Baseline level is highlighted.
Requirements live in the lead engineer's head. When asked 'what does this product need to do?' the answer is a hallway conversation. New team members reverse-engineer requirements from the existing product because nobody wrote them down. When the customer changes their mind, the engineer adjusts the design without documenting what changed or why.
AI cannot perform requirements analysis, traceability, or compliance checking because no requirements exist in any documented form.
Write down product requirements in any format — even a Word document listing functional requirements, performance targets, and regulatory obligations establishes a starting point.
Requirements exist in Word documents and PowerPoint decks scattered across project folders. Each engineer writes requirements differently — some use 'shall' statements, others write narratives. There is no standard numbering, no priority system, and no traceability to test cases. Finding the requirements for a specific product feature means searching through multiple documents and hoping you found them all.
AI could parse requirement documents using NLP but cannot reliably map requirements to design features or test cases because there is no consistent structure or traceability links.
Standardize a requirements template with unique IDs, priority levels, acceptance criteria, and verification method for each requirement.
A standard requirements template is used across projects. Each requirement has an ID, description, priority, acceptance criteria, and verification method. Requirements are stored in a shared spreadsheet or basic requirements tool. Engineers can find all requirements for a product in one place. But traceability to design elements and test cases is maintained manually in separate documents — 'Requirement REQ-042 is verified by Test Case TC-017' lives in a cross-reference spreadsheet someone updates periodically.
AI can generate requirements reports, identify gaps in coverage, and flag requirements without acceptance criteria. Cannot perform automated traceability analysis because requirement-to-test linkages are in separate manual documents.
Implement a requirements management tool (DOORS, Jama, Polarion) with built-in traceability that formally links requirements to design elements, test cases, and compliance evidence.
Requirements are managed in a dedicated tool with formal traceability. Each requirement links to design elements (CAD features, BOM components), test cases (with pass/fail status), and regulatory standards (with compliance evidence). Coverage matrices are automatically generated. An engineer can click on any requirement and see 'which design feature implements this, which test verifies it, and what is the current compliance status.' Requirements change history is complete.
AI can perform automated requirements traceability analysis, identify untested requirements, detect conflicting requirements, and generate compliance evidence packages. Can predict which requirements are at risk based on test failure patterns.
Implement schema-driven requirements with formal entity relationships, machine-readable acceptance criteria, and API-accessible traceability links so AI agents can query and reason over the requirements model programmatically.
Requirements are schema-driven entities with formal relationships to every aspect of the product development lifecycle. Acceptance criteria are machine-readable — an AI agent can evaluate 'is this requirement met?' by querying test results through the API. Regulatory mapping is explicit — each regulatory clause links to the requirement(s) that address it and the evidence that demonstrates compliance. An AI agent can answer 'show me all unverified safety-critical requirements for products shipping to EU markets' with a single query.
AI can perform autonomous requirements validation, auto-generate test plans from acceptance criteria, and produce regulatory compliance packages without manual assembly. Full requirements lifecycle automation is possible for routine requirement types.
Implement real-time requirements streaming where requirement changes, test results, and compliance evidence publish as events the moment they occur, enabling continuous compliance monitoring.
Requirements are a living, self-maintaining specification that evolves with the product. Customer feedback auto-generates requirement candidates. Test results continuously update compliance status. Regulatory changes automatically flag affected requirements. The requirements specification documents itself — every change, every verification, every compliance decision is captured as it happens without manual intervention.
Fully autonomous requirements lifecycle management. AI maintains the complete requirements model, generates test plans, monitors compliance, and adapts to regulatory changes in real-time.

Capabilities That Depend on Design Requirement Specification
Other Objects in Product Engineering & Development
Related business objects in the same function area.
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.
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.
Material Specification
EntityThe 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.
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.
Design Standard and Constraint Rule
RuleThe codified engineering standards, design rules, and constraints that product designs must satisfy — including company design standards, industry standards (ASME, ISO), regulatory requirements, manufacturability constraints, and the prohibited-materials lists that bound the design space.
Engineering Change Process
ProcessThe end-to-end workflow governing how product changes are proposed, evaluated, approved, and implemented — defining change request submission, impact analysis steps, review board composition, approval routing, implementation coordination across engineering-manufacturing-supply chain, and effectivity cutover procedures.
