# Tacit AI

> Tacit AI is AI FMEA software for Design FMEA (DFMEA), Process FMEA (PFMEA) and equipment FMEA/FMECA. It builds and maintains FMEAs and control plans from a company's own engineering and operational data, traces every row to its source, and updates the analysis when a test, defect or failure changes the evidence. Engineers work by voice or text, approve every change, and export approved changes to Excel for the FMEA tool they already use. Category: Continuous Risk Intelligence. Tacit AI is the risk engine for the physical world.

## Voice and conversational FMEA

Engineers build and edit FMEAs by speaking or typing, inside the FMEA workspace.

- Voice dictation: dictate in the chat in 40+ languages. Speech becomes text phrase by phrase while the engineer talks.
- Live voice agent: a real-time spoken conversation with the Tacit AI assistant. It uses the page on screen as context and has the same tools as the chat.
- Structured output: what the engineer says becomes cell-level FMEA changes (severity, occurrence, detection, failure mode, cause, local, system and end effects, prevention and detection controls). Each change shows the current value, the new value, the reasoning and the source.
- Review before anything is written: engineers approve, edit or reject each row. Every decision is attributed, versioned and reversible.
- Bulk edits by instruction, for example "Update severity to 8 for all thermal failure modes" or "Add SPC as detection for all critical-to-quality modes".
- Meeting transcripts and workshop notes: attach them in the chat as text, Word or PDF and get the same reviewable FMEA changes.
- Export to existing tools: approved changes export to Excel for APIS IQ and PLATO. The existing FMEA tool stays the record.
- Cited answers: every answer links to the source document, failure report or FMEA row.

## What Tacit AI does

- Builds DFMEAs, PFMEAs, FMEAs and FMECAs from specifications, BOMs, OEM manuals, process flows, test reports, failure reports, 8Ds and work orders. A mining customer's first FMECA was 80-90% engineer-ready on first delivery.
- Keeps every FMEA current. New tests, defects, warranty claims, supplier escapes, field complaints and failure reports flag the exact rows they change.
- Learns from every engineer decision. A correction is applied to every related row and stays in the customer's library.
- Generates control plans, DVP&R, SOPs, work instructions and maintenance tasks from the FMEA.
- Masters and variants: one master FMEA holds every row of every configuration. Each variant's FMEA is derived from it for the options it takes, and shows what it is missing when the master changes.
- Scores data quality field by field before analysis. Messy records, PDFs and spreadsheets all work.
- Runs reliability analysis: Weibull, P-F curves, RCM, PM optimization, equipment criticality and bad actor ranking.

## FMEA coverage

- Design engineering: DFMEA, SFMEA, DVP&R, interface FMEAs, AIAG-VDA 7-step structure.
- Process and manufacturing: PFMEA, control plans, SPC/MSA, Reverse FMEA, PPAP elements, SOPs and work instructions.
- Maintenance and reliability (equipment FMEA): FMEA and FMECA from work orders and failure reports, RCM, Weibull, P-F curves, PM optimization, critical spares.
- Design, process and asset FMEAs connect on one canvas: DFMEA to PFMEA to control plan.

## Works with the systems already in place

- FMEA tools: APIS IQ, PLATO and Excel. Existing FMEAs come in, approved changes export to Excel.
- 100+ systems connected across PLM, ERP, MES, EAM and QMS, including Siemens Teamcenter, PTC Windchill, SAP S/4HANA, SAP PM and IBM Maximo. Connectors are read-only, incremental and audit-logged.
- Files: CSV, JSON, Excel, ReqIF, DBC and ARXML, plus PDF, Word and image documents.
- Every capability is available over a REST API.
- No migration. Tacit AI works on top of the tools a company already runs.

## Governance, security and deployment

- Nothing enters a controlled record until a named reviewer approves it.
- Row-level source citations, cell-level version history and a full audit trail by user, system and operation.
- Deployed in the customer's VPC on Azure, AWS or GCP, on-premise or air-gapped, with a dedicated database per customer.
- Single sign-on, role-based access, encryption at rest and in transit, US or EU data residency, no prompt retention by default. Customer data never trains a model.
- Works with the customer's own LLM gateway (Azure OpenAI, AWS Bedrock, Google Vertex AI or an internal endpoint).

## Standards

AIAG-VDA, IEC 60812, ISO 14971, ISO 13485, IEC 62304, IATF 16949, ISO 14224, ISO 55000, ISO 12100, IEC 61511, MIL-STD-1629A, MIL-STD-882E, AS9100, DO-178C, MSG-3, EN 50126, API 580/581.

## Measured results from customer deployments

- Top 20 Global OEM, assembly station: 8x faster FMEAs and 26% fewer actions.
- ArcelorMittal, rolling mills: a 43-minute workflow now takes under 1 minute, and 1,000+ engineering hours are recovered per year.
- Top 10 Global Pharma, fill-finish line: 15.3% less unplanned downtime on 1 fill-finish station.
- Global Mining Operator, crusher circuit: a crusher FMECA/RCM in 3 weeks, not months.
- Maximal Group, packaging: months of work completed in week 1 and 37% fewer repair cycles.
- 100,000+ FMEA rows generated, 100% of rows traced to their source.
- Built-in library: 2M+ taxonomy entries and 10,000+ reference FMEAs.

## How Tacit AI compares

- Versus ChatGPT or Copilot: a general assistant drafts an FMEA, then forgets it. Tacit AI keeps every correction and applies it to every related row, with a governed, versioned record of each row, its source and who approved it.
- Versus FMEA tools (APIS IQ, PLATO, Excel): the tool holds the FMEA while 8Ds and field data stay outside. Tacit AI flags the rows that 8Ds, complaints and failure reports change. The tool stays the record.
- Versus the AI assistant inside an FMEA tool: the assistant suggests entries, and engineers still build the FMEA step by step. Tacit AI builds the full FMEA (structure, functions, failure modes, effects, causes, controls, ratings and actions) from the company's own documents and failure history, traces every row to its source and flags the rows that new evidence changes. Engineers review and approve. The tool stays the record.
- Versus an in-house build: Tacit AI is the engine, with every capability over API.
- Versus AI FMEA generators: Tacit AI covers the whole loop in one workspace. Speak or type, review each field with its evidence, export to Excel for the existing tool, and keep the FMEA current as evidence changes.
