Product specifications created by design teams were checked item by item against PRDs, acceptance criteria, and safety standards. AI detected missing requirements and inconsistent thresholds with evidence before drawing release.
"The specification is finished, but are we sure it covers every PRD and acceptance-criteria requirement?" This concern is familiar to design and QA teams, so we used INDX Compliance to solve it in practice. This article walks through the real product screens.
A product design team was about to perform a final review of product specification v0.9 just before drawing release. They had designed against the product requirements document (PRD), but at the review table they still had to check one item at a time to see which requirement was reflected where in the specification.
Numerical requirements such as operating temperature, power consumption, and communication specifications are scattered across different pages. When acceptance criteria, safety standards, and internal design standards also need to be checked,manual comparison across multiple documentstakes hours. If an omission is found after drawing release, it can directly cause major rework through a design change.
Challenges encountered
First, we did not configure anything difficult."Check whether this specification satisfies the PRD, acceptance criteria, and safety standards."We entered that in the same language someone would use with a manager. The AI then automatically assembled the procedure, or review viewpoints, to check.
Your instruction, in plain language
"Check whether product specification v0.9, before drawing release, satisfies the product requirements document (PRD), acceptance criteria, and safety standards. Flag missing requirements and threshold inconsistencies with evidence."
01Import requirements and standards
Ingest the PRD, acceptance criteria, safety standards, and internal design standards
02Evaluate conformity by specification item
Compare specification statements and thresholds against each requirement one by one
03Verify decision evidence and confidence
Confirm that the cited PRD clauses and thresholds exist
04Final human review
Route only needs-review and non-compliant items to Design and QA
No programming knowledge or complex rule setup is required. You can inspect and edit the generated workflow, then reuse the same review viewpoints as often as needed.
After saving and running the workflow, the AI checks whether the specification satisfies each PRD requirement one by one. The results are consolidated on this screen. The key point is thatevery decision always includes which document and condition support it. Tap a row and the source evidence opens in place.

For the guaranteed operating environment,the operating temperature range must be -20℃ to 60℃. Operation outside this range is excluded from warranty coverage.
Specification v0.9 states 0℃ to 50℃, which does not meet the PRD temperature range. Requirement not met.
This time, the AI found "the operating temperature range stayed at 0-50℃ in the specification, short of the PRD requirement of -20-60℃". This unmet requirement would be costly if found after drawing release because it could trigger a design change. INDX detected a numerical inconsistency that is easy to miss in manual review, with evidence, before release.
The 4 items the AI marked as pass can be cleared quickly because evidence is attached. Humans spend judgment ononly the 4 items that need attention: 3 needs-review and 1 non-compliant item. The specification reviewer returned the non-compliant temperature-range item to Design, reran the corrected specification v0.91, and finally approved and finalized it.
Final review (human approval)
The PRD requires -20-60℃. Specification v0.9 only states 0-50℃, so the requirement is not met. Return to Design.
Humans review only the 4 needs-review and non-compliant items.The 4 passed items can be cleared with evidence, so reviewers can focus on judgment.

All operations and decisions are recorded in a tamper-resistant audit logYou can fully trace who decided what, when, and based on which evidence, so it can be used directly for quality audits and design-change history management.
A conformity check that had taken two full days manually was completed from viewpoint preparation to final approval inhalf a day. Most importantly, it caught a temperature-range requirement gap before drawing release that manual review had missed, which gave the reviewer the most reassurance.

Key points from this case
This example used a product specification, but INDX Compliance works the same way across use cases. Provide the benchmark documents, such as the PRD, acceptance criteria, safety standards, and internal design standards, together with the document you want checked, then compare them with evidence. Internal policy consistency checks, contract reviews, application-deficiency checks, and any other work that involves matching against rules can use the same workflow.
Bring a policy, contract, or application document, and we will demo the actual judgment screen. Closed-network and on-premise deployments are supported.
Use caseWe compared a newly revised information security management policy against higher-level basic policies, work rules, and APPI requirements, then had AI identify conflicting clauses with evidence.
Use caseWe compared a near-final specification against Patent Act Article 36, JPO formatting, and internal filing guidelines, then had AI identify support and clarity issues in the claims with evidence.
Use caseBefore the internal audit, AI performed a first-pass check on whether the quality manual and department procedures met ISO 9001:2015 clauses 4-10, detecting missing corrective-action and audit provisions with evidence.
