GCRI · システミックリスク管理

保証と訂正

Assurance asks whether risk management works as described; correction makes sure that when it does not, records and decisions change. Internal audit, independent review, incident investigation and learning システム provide the checks. This page sets out how assurance is organised, why it can miss systemic weaknesses, and how corrections are recorded so that the evidence behind a decision stays traceable after the facts change.

Assurance and correction on the record.

02質問

Assurance and correction: how the risk develops.

Evidence, review and methods correction. The dossier below sets out how the risk develops, what is measured, where the data come from, how it is modelled and who decides.

メカニズム

Assurance tests what it is shown

Reviews examine the processes and records put in front of them. Risks that fall outside the scope, or between the scopes of several reviewers, go untested.

メカニズム

Investigations stop at the first cause

Incident reviews that end at the person or component closest to the failure miss the organisational and design conditions behind it. Those conditions remain and produce the next incident.

メカニズム

Corrections must reach the record

When an assumption, dataset or model proves wrong, decisions built on it need revisiting. Without versioned records, the correction is made in one place and the error persists elsewhere.

メカニズム

Actions decay before closure

Audit and incident actions are agreed, then deferred as priorities shift. Overdue actions accumulate and the weaknesses they were meant to fix stay open.

Assurance checks that risk evidence in every domain can be trusted.

Assurance practice is designed for the 手法と技術シリーズ. The Three Lines Model of 2020 separates management, risk oversight and independent assurance; verification evidence would follow NS-11 of the proposed Nexus Standards.

  • Published audit and correction records.
  • Lessons where assurance missed a failure.

09中核となる問い

What assurance experts ask.

  • Is the evidence that controls work independent of the people who run them?
  • Are models validated against data they were not built on, and are their limits documented?
  • When an error is found, is it corrected openly, with a record of what changed and why?
  • Do near misses and small failures lead to learning, or are they explained away?
  • Who checks the checkers: is there a route for staff and outsiders to raise concerns that bypasses the line being reviewed?
  • Are corrections traced through to every decision, report and model that relied on the flawed result?
10メカニズム

Why assurance weakens.

Assurance tends to erode quietly. Reviews become routine, findings repeat from one cycle to the next and the people being reviewed learn what reviewers look for. Major failures often follow years of assurance reports that described controls as effective.

独立性

Too close to the work

Reviewers who depend on those they review, or who designed the controls, find fewer problems.

Form over substance

Checking the paperwork

Assurance that checks whether processes are documented rather than whether they work.

Silent edits

Unrecorded change

Methods and models changed without records, so no one can tell what earlier results relied on.

11手法と限界

How assurance and correction work.

  1. 01

    モデル検証

    Independent testing of models against data, benchmarks and expert review, using uncertainty quantification and model validation. Limits: validation is harder for models of rare events.

  2. 02

    Internal and external audit

    Independent review of controls and governance. Limits: audit samples, and its findings depend on scope.

  3. 03

    Version control and provenance

    Records of data, code and method versions behind each result. Limits: requires discipline to maintain.

  4. 04

    Open correction

    Published corrections with reasons and dates. Limits: requires a culture that values correction over reputation.

14質問

質問と回答。

What does assurance mean in risk management?
An objective examination that gives a stated level of confidence that risk management, controls and governance operate as intended, provided by internal audit, external reviewers or other independent functions.
Why trace organisational factors in investigations?
Because the conditions that allowed a failure, such as design, staffing, incentives and procedures, usually outlast the individual event. Fixing only the immediate cause leaves them in place.
How are corrections handled on these pages?
Each correction to published evidence is recorded with its date, what changed and why, and earlier versions remain traceable, so readers can see how evidence evolved.
Why publish corrections openly?
Because others may have relied on the earlier result. A visible correction lets them check whether their conclusions still hold.
Is assurance the same as audit?
Audit is one form of assurance. Model validation, peer review and independent challenge are others.
Can the platform provide assurance on my risk management?
No. It does not audit, validate or certify any organisation’s risk management.
