A product manufacturer delivers a session about their product category. An architect or engineer attends. The session covers technical performance data, installation guidance, relevant standards and regulations, and application case studies. The manufacturer hopes the professional will specify their product. The professional hopes to learn something that will help them make better decisions. Both things can be true simultaneously. The structural conflict of interest isn’t that the manufacturer wants the professional to specify their product — that’s transparent and expected. The conflict is that the manufacturer is also the source of the information on which the specification decision will be based.
The structure of the conflict.
Independent testing and manufacturer-supplied data are not the same category of evidence, even when both are accurate. The scope of what a CPD session covers is set by the manufacturer, and it rarely matches the scope of what a specifier actually needs to know — competitor comparisons, failure modes, lifecycle data, edge cases where the product underperforms. There’s a structural incentive to present the most favourable interpretation of technical evidence, not because the manufacturer is dishonest, but because that’s what any organisation does when presenting information about its own product. None of this makes manufacturer CPD dishonest. It makes it structurally partial, in the same way an investment bank’s research note on a company it has underwritten is structurally partial — accurate, useful, and shaped by the source’s position.
What this means for measurement.
If a manufacturer delivers a CPD session and the attendee says they’ll change a specification decision as a result, is that evidence the session was educational, or that it was effective marketing? The honest answer is both — and distinguishing them matters. Behavioural intent signal alone can’t make this distinction on its own. But patterns across many sessions can. A session with high Practice Change Intent but low Assumption Challenge scores may be influencing decisions without changing the underlying reasoning behind them — attendees are moving toward a specification, but not because they’ve reconsidered anything, just because they’ve been told to. That’s a signal worth having, and it’s invisible in an attendance record or a satisfaction score.
What good manufacturer CPD looks like.
This isn’t a condemnation of manufacturer CPD — much of it is genuinely excellent, and the technical knowledge manufacturers hold is irreplaceable. Good manufacturer CPD presents its technical case and then presents the questions a specifier should ask of any product in the category, including the manufacturer’s own. That’s the CPD that earns high Assumption Challenge scores. It’s also the CPD that earns long-term specification trust rather than one-project conversion — a specifier who’s been given the tools to interrogate a category, not just a pitch for a product, is more likely to come back.
What the signal actually does.
The signal doesn’t judge. It records what attendees intended to do differently. Over time, those patterns tell a more complete story about what kind of influence a session exerted than any accreditation badge can. A session that consistently produces intent to change specifications without any accompanying evidence of reconsidered assumptions looks different, in aggregate, from a session that produces both — and that difference is exactly what a specifier, or a provider evaluating their own programme, would want to know.
FAQs
Manufacturer CPD is structurally partial — the provider has a financial interest in the specification decisions of attendees. This doesn’t make it dishonest. Most manufacturer CPD contains accurate technical information. But partial information, even accurate partial information, is not the same as independent information. Professionals attending manufacturer CPD are right to note the structural context and supplement it with independent technical sources.
Sessions designed primarily to educate typically acknowledge the limitations of the product or system they cover, present comparative technical context, and address the questions a specifier needs answered regardless of which product they ultimately choose. Sessions designed primarily to persuade typically focus on one product’s advantages, use case studies that position that product favourably, and avoid comparative context. The CPD Sniff Test provides a pre-attendance framework for identifying which type of session you’re likely attending.
CPD Impact tracks intent signal anonymously across session types. As the dataset grows, patterns across manufacturer and independent CPD will become visible. Early data is available in the directory — filter by provider type to see the current signal distribution.
