• Inconsistent Shared Model
  • A second instance is intelligence-sharing before a coordinated threat: two agencies each hold a defensible threat model from their own collection, the channels never cross, and the joint model does not exist until an operational decision forces it.

    This sourcePre-crisis intelligence-sharing failure in which each agency held a defensible threat model from its own collection (stovepiping) and the joint model never existed until the forcing event.

    The report documents pre-9/11 barriers that kept NSA and CIA intelligence from reaching FBI criminal investigators, i.e. intelligence channels that did not cross.

    “relevant information from the National Security Agency and the CIA often failed to make its way to crimi- nal investigators.”

• Stovepipe System
  • In the intelligence community the canonical case is pre-9/11 agencies each building their own collection, analysis, and dissemination stacks with incompatible information systems, so cross-agency fusion required political coordination because no shared substrate existed; the remediation — a Director of National Intelligence, fusion centers, shared infrastructure — was an explicit horizontal-layer extraction.

    This sourceDocuments pre-9/11 intelligence agencies operating incompatible stovepiped information systems with no shared substrate, and the remediation toward a Director of National Intelligence, fusion centers, and shared infrastructure (the report explicitly calls for 'smashing the stovepipes').

    The report describes a loose confederation of separate agencies, each with its own collection and analysis, and compartmented information, but not incompatible formats or identity models.

    “mation was compartmented in order to protect it against exposure to skilled and technologically sophisticated adversaries.”

Domain-specific

• Unity-of-Command Breakdown
  • The FDNY and the NYPD operated largely separate command posts with separate radio networks and no single overall incident commander coordinating them

    This sourceThe separate FDNY and NYPD command posts and radio channels at the World Trade Center, the two departments each operating autonomously without a unified command. The NYPD aviation reports that the North Tower might collapse and the FDNY lobby chiefs' statement that they received no reports from the police helicopters. The Commission's finding that the FDNY and NYPD operated autonomously without coordinated command, and that this lack of shared knowledge affected command-and-control decisions.

Verification

Does it exist? Not checked yet. This entry carries no identifier to resolve. It was extracted from the citation as written in the article, normalized, and deduplicated against the rest of the registry.

Does it back the claim? Read against the text for 3 of 3 citations: 1 supported, 2 supported in part. Each verdict is shown under its citation below, with what in the work backs the sentence.

Support is checked per citation rather than per work — the same source can be cited soundly in one article and wrongly in another. Per-citation recording began recently, so a citation with no recorded check is a gap in the record rather than evidence it went unchecked.
