Which cognitive biases were evident in Avaya's collapse?

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

Did these cognitive biases cause Avaya's collapse?

Decision Intel identifies reasoning-risk indicators correlated with poor outcomes — it does not claim to establish causation. That honesty is the procurement weapon: a CSO can defend a score that names the risk indicators a committee should pressure-test, not one that pretends to prove the cause. Inside-View Dominance and the other documented patterns were detectable in the reasoning before the outcome was known; whether they caused it is a question no audit can settle — too many other factors (market, timing, execution) are in play. A reasoning audit names the risk indicators a committee should pressure-test, not a verdict it should accept.

What is Decision Intel's reasoning audit?

Decision Intel runs a Recognition-Rigor Framework (R²F) audit 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.

Avaya Leveraged Buyout into Two Chapter 11 Filings

Estimated impact: Chapter 11 in 2017 and again in February 2023; the second filing carried approximately $780 million of new committed financing on the company’s own aggregate — $628 million of debtor-in-possession commitments that roll into the exit facilities, plus $150 million of new money at exit; sponsor equity from the 2007 buyout was not recovered

In 2007 Silver Lake and TPG took Avaya — the enterprise communications business spun out of Lucent — private at $17.50 per share in cash. The proxy put the transaction at roughly $8.49 billion and disclosed the shape of the funding: about $2.193 billion of equity contributed to the acquiring parent against up to $6.0 billion of committed debt financing. The operating thesis had to carry that fixed-charge structure through a platform transition already visible at signing, as enterprise telephony moved from on-premises hardware toward software and, later, cloud delivery. The company filed for Chapter 11 in 2017, emerged and relisted in 2018, and filed for Chapter 11 a second time in February 2023 — that second filing accompanied by roughly $628 million of debtor-in-possession commitments, which the company disclosed would roll into its exit facilities rather than sit alongside them, plus $150 million of new money at exit; the filing puts the new committed financing at approximately $780 million in total.

Decision context

Whether to take a maturing enterprise-communications business private at a premium, funding roughly three-quarters of the purchase with debt the operating company would service, while the product category it led was moving to a delivery model with different economics — and without a disclosed case for what the fixed charges do if the transition runs slower than the plan.

Lessons learned

The capital structure decided the outcome before the operating plan did: a business funded roughly three-to-one debt-to-equity has to service fixed charges out of the same cash flows that would otherwise fund a platform transition, so the transition and the debt compete for the same money.
A category leader in a market that is changing delivery model is not a stable annuity; underwriting it as one is what converts a slow transition into a solvency event.
A second Chapter 11 six years after emerging from the first is evidence that the restructuring addressed the balance sheet without resolving the operating thesis underneath it.
