Section 200 is where the conceptual framework is applied by professional accountants in business, and 200.6 A2 sits under a heading the Code wrote for this exact purpose. It names self-interest threats first, and its three examples are recognisable to anyone who has adopted a tool in a hurry. The data available might not be sufficient for the technology to be used effectively. The technology might not be appropriate for the purpose it is being put to. And the accountant might lack sufficient information and expertise, or access to an expert, to use the technology and to explain it and its appropriateness. Each is stated as a threat to compliance with the fundamental principles, which means it has to be evaluated and addressed rather than accepted as a feature of the environment.
The self-review limb is the half that gets skipped, and it is the more interesting one. A self-review threat arises where the technology was designed or developed using the knowledge, expertise or judgement of the accountant or of the employing organisation. Read plainly, a finance team that specified, tuned or trained a model is now reviewing the output of its own judgement — the definition of the threat, arriving somewhere nobody expects it. “We built our own forecasting model” is normally offered as evidence of control; under this paragraph it is the fact that creates the threat. The answers are ordinary ones: separate the people who set the logic from the people who review its output, or bring in something the team did not build to challenge it. The independent validation line supervised institutions draw is the same idea reached by another route.
200.7 A4 supplies three factors bearing on how significant the threat is, and all three are organisational rather than personal: the level of corporate oversight and internal control over the technology, third-party assessments of its quality and functionality, and regular training so that relevant employees can understand, use and explain it. That matters for how an assessment is written. An individual accountant cannot change the level of corporate oversight, but they can establish what it is, and the paragraph makes that fact part of their own evaluation. Where oversight is thin the threat is more significant and the safeguards have to be heavier at the individual level, which is the practical link between this paragraph and the judgement R220.8 requires each time an output is used.
