How is sensitive data protected?

All documents are encrypted with AES-256-GCM at rest and TLS 1.2+ in transit. A GDPR anonymization layer removes PII before any AI processing. Hosted on Vercel + Supabase (both SOC 2 Type II); Decision Intel’s own product-level audit is targeted for Q4 2026.

How long does integration take?

Less than 30 minutes. Upload documents directly, connect via OAuth for Slack, or use our REST API for bulk processing.

How does outcome tracking work?

Outcomes are detected automatically from follow-up documents, Slack messages, and web intelligence. You confirm with one click. Each reported outcome makes your future analyses more accurate.

How is Decision Intel different from ChatGPT or a general AI assistant?

ChatGPT gives one opinion from one model: ungoverned, untraceable, unaudited. Decision Intel is the reasoning audit platform. Most tools audit your data; we audit your reasoning — and catch the fatal blind spots in strategic memos before the committee does. It measures the noise in your reasoning the same way Kahneman did in the insurance underwriter study, simulates an AI boardroom of CEO, CFO, and board personas, runs what-if interventions against a 143-case public reference library, and compounds every confirmed outcome back into a calibrated Decision Quality Index your audit committee can defend. Not a chatbot; a reasoning audit, checkable from memo to outcome.

Which cognitive biases caused Tesla's exceptional outcome?

3 bias patterns are documented in this case, led by Overconfidence Bias. The full set: Overconfidence Bias, Planning Fallacy, Anchoring Bias. Each is mapped to Decision Intel's 22-bias R²F taxonomy with stable IDs and academic citations.

What is Decision Intel's reasoning audit?

Decision Intel runs a 12-node Recognition-Rigor Framework (R²F) pipeline on strategic memos, detecting cognitive biases from a 22-bias canonical taxonomy and producing a Decision Quality Index (DQI) score. The audit produces a hashed, tamper-evident Decision Provenance Record (DPR) suitable for audit-committee review.

Tesla Gigafactory Vertical Integration Bet

Estimated impact: $800B+ market cap; accelerated global EV transition by 5-10 years

Decision Quality Index (simulated)

Excellent · 3 biases detected

In 2014, Tesla announced the Gigafactory — a $5 billion battery manufacturing facility that would produce more lithium-ion batteries annually than the entire world's 2013 output. The decision to vertically integrate battery production (with Panasonic as partner) was considered reckless by automotive analysts. Battery costs were the primary barrier to EV adoption, and Tesla bet that manufacturing scale would drive costs below $100/kWh. By 2020, Tesla achieved this target and became the world's most valuable automaker.

Decision context

Whether to invest $5B in vertically integrated battery manufacturing at unprecedented scale, or continue purchasing batteries from third-party suppliers like every other automaker.

Lessons learned

Overconfidence bias was present and arguably necessary — no one without extreme conviction would have committed $5B to an unproven manufacturing concept. But the underlying physics-based analysis was sound.
Planning fallacy was severe (the Gigafactory was years late and billions over budget) but the strategic direction was correct, and Tesla maintained sufficient capital to survive the delays.
Survivorship risk is high: Tesla nearly went bankrupt multiple times during 2017-2019 "production hell." The success is real, but the path was far riskier than it appears in hindsight.
