The documented case study operates in industrial B2B with a specific function many executive committees underestimate. It is not promotional material. It is the piece of evidence the internal sponsor uses to defend the supplier's proposal before their committee, and its absence or mediocrity can invalidate all the prior commercial work.

TrustRadius documented in its B2B Buying Disconnect Report 2023 a revealing figure. 64 per cent of B2B buyers revisit at least one documented case study before signing a significant transaction. When the supplier does not have a case published in the buyer's specific sector, the probability of closure falls approximately 40 percentage points compared with equivalent transactions where a case is available.

A complementary figure comes from LinkedIn and Edelman in their B2B Trust Barometer 2024. 84 per cent of B2B CEOs and vice-presidents use peer references to make purchasing decisions above 100,000 euros. The peer reference is not an informal conversation: it is the consultation with an equivalent customer of the supplier who has already lived through the transaction being considered, and it usually rests on a documented case that frames the conversation.

The frequent operational error in mid-sized industrial companies is to produce case studies as a generic, replicable, editorial marketing deliverable. The consequence is that published cases are many and useful for few. Commercial leadership finds that its most relevant transactions lack the specific case the buyer needs to revisit, while the corporate library contains generic cases without traction.

Three attributes define a case study that fulfils its commercial function. Sectoral specificity: the case belongs to the buyer's exact sector, not to a near analogous sector. Verifiability: the case includes defensible quantitative data, nominal identification of the customer where possible, and ideally the customer's willingness to receive enquiries from interested peers. Articulation of before and after: the case documents the customer's initial situation, the intervention performed and the measured result, not the mere enumeration of services rendered.

For general management, the organisational implication is direct. Building the case library is not a pure marketing project. It is a commercial leadership project requiring coordination with technical service, application engineering and, above all, negotiated access to the customer themselves. Without that coordination, cases remain in internal templates without real commercial value.

Three levers move the indicator in companies that approach the construction with discipline. An explicit map of the sectors and transaction types where the company needs publishable cases, with prioritisation by estimated commercial value. A post-delivery capture process that, in every significant transaction, contemplates the negotiation of the publishable case as a natural part of project closure. Compensation for the customer who agrees to act as a referee, not necessarily monetary, but in the form of preferential access, service priority or sectoral recognition.

The standard objection is that many industrial customers are reluctant to allow publication of their case for reasons of competitive confidentiality. The objection is valid in a proportion of cases and resolvable in a significant other. Negotiating intermediate formats — anonymised data, generic descriptions of the customer with specific technical detail of the operation — usually resolves most resistance without sacrificing the commercial usefulness of the case.

A second implication concerns the production rhythm. The case library is not built with intermittent sprints. It is built with sustained cadence, explicit assigned responsibility and follow-up discipline by account. Without that discipline, the library ages and loses relevance, and the buyer of the next quarter does not find the case they need to defend the transaction.

Recognising the sectoral case study as a strategic commercial asset, and not as an editorial deliverable, orders organisational priorities that in many mid-sized industrial companies remain diffuse.
