Competitive data sharing only works when the rules protect everyone in it. This guide covers the governance that makes it possible: neutral administration, the open, closed and delayed reporting models, the access controls that decide who sees what, the usage rules participants follow and the enforcement that keeps trust intact month after month.
Why competitors share data at all
On the surface, sharing sales data with rivals sounds unthinkable. It works because competitive data sharing is structured so that no participant is exposed. In closed reporting projects, no participant ever sees another's individual figures, only the anonymised, aggregated market. Everyone contributes their own numbers and everyone gets the whole picture back - the give-to-get exchange behind industry market share data.
The value of that picture far outweighs the discomfort of contributing. Our customers tell us they are happy to share commercially sensitive information into a platform that is safe, impartial and - in closed reporting - anonymous. The purpose is worth stating plainly: sharing data sharpens competition rather than blunting it, because better demand intelligence lets participants build products the market actually wants, and consumers see more choice as a result.
The trust architecture
Trust in a data sharing programme is structural, not a promise. In all closed-reporting projects, PowerStats anonymises and aggregates every contribution before it appears, applies thresholds so small numbers cannot expose an individual participant, and administers the programme as a neutral third party with no stake in any participant's results.
The platform is ISO 27001 certified (information security management) and ISO 9001 certified (quality management), hosted exclusively on Microsoft Azure and GDPR compliant, with bank-grade encryption, audit-ready system logs and a record of "0 security incidents, ever". Participants forever retain ownership of their submitted data: PowerStats does not buy or sell participant data, and it is licensed between participants only by prior agreement. The full picture is on our data and security page.
Reporting models: open, closed and delayed
A programme's reporting model defines how much competitor detail each participant can see, and it is one of the earliest and most consequential governance decisions in any project.
- Closed reporting - each participant sees only its own data plus a single aggregated total for everyone else. No individual competitor can be identified. This is the lowest level of disclosure and the default starting position.
- Open reporting - every participant sees individual competitor results by brand. It delivers the richest competitive intelligence, and every participant's data is equally visible to the others.
- Delayed reporting - a hybrid that starts closed and becomes open over time. Data always arrives on schedule; brand-level detail stays hidden for the most recent months - six is the practical standard - then opens retroactively as each month passes the window.
The choice is made by the participants themselves, typically through the board of the sponsoring association, and it requires consensus. PowerStats deliberately stays neutral: we facilitate the process but neither prescribe nor recommend a model. Regional regulation shapes what is viable - open reporting is common in Australia and New Zealand, delayed or closed models prevail in Europe and projects in the United States are almost always closed. Transitions run in one direction only, from closed toward open, because released brand-level data cannot be unseen. We unpack the negotiation dynamics in how industries choose a reporting model.
Geographic granularity is part of the same negotiation: a group might pair closed reporting with fine-grained geography, or open reporting with broader sales zones. Brand visibility and geographic detail are two levers the group can trade to reach a consensus that works for enough participants.
Who makes the rules
Governance has a human structure behind it. The sponsoring association acts as an honest broker, and most groups maintain a statistics committee - representatives of participating companies who meet at least annually to raise issues, debate the model and resolve concerns before they become disputes.
Good facilitation also protects the quieter voices. Smaller participants often need the data most and speak up least, and deliberate governance keeps them heard alongside the biggest names in the room - a theme an experienced association secretariat manager explores in giving smaller members a voice. The foundation underneath it all is a legally binding agreement between the parties that defines the dos and don'ts: without one, misuse cannot even be defined. How a new programme reaches that point is covered in setting up an industry data sharing programme.
Controlling who sees what
Not everyone in a participant organisation should see everything. Role-based, need-to-know access lets a programme show each user only the view appropriate to their role, and lets territories be grouped or anonymised where individual zones would otherwise be exposed.
The same controls make wider access safe. Dealers can hold their own login confined to their own view, which strengthens rather than threatens the relationship - a dynamic we explore in dealer and OEM relationships: trust, data and power. Subject to association preference, access can even extend to the finance providers and suppliers around an industry, through the calibrated approaches described in the industry gains of associate member access, without compromising any participant's position.
The usage rules: internal use only
The two misuses seen most often in competitive data sharing programmes are promotional use and access-boundary breaches. Declaring a number-one position at an industry event, or advertising market share, breaks most programme rules even when the position is genuinely true. And a multi-brand dealer that holds data because it reports for one brand does not thereby gain the right to pass it to the other brands it represents.
The principle that holds the line is internal use only. Inside the OEM-dealer relationship, the data can be used for accountability - telling a dealer how its share compares with the market average is exactly what dealer performance benchmarking is for. The same number becomes a breach the moment it is published or used to market a position.
A rule that lives only in someone's memory is not a rule. The code of conduct needs to be documented, tabled regularly and repeated through the association's communications - the most efficient approach is a thirty to forty-five second bolt-on to the anti-competition statement a chair already reads at the start of each meeting. We cover the full set of dos and don'ts in governing industry data: why rules protect trust.
Enforcement that protects trust
Enforcement should follow protocol, not opinion. Best practice leads with education, then a formal written warning, and only then, as a last resort, exclusion - with the criteria objective and applied by protocol rather than decided by consensus, because a committee vote hands veto power to the very competitors who gain most from removing a rival.
Transparency after a rule breach does more to protect trust than silence ever could: a clear, simultaneous memo to members - what happened, how it was contained, what has changed - shows the governance is real and working. Handled this way, a breach can strengthen a programme's credibility rather than damage it.
Preventing reverse-engineering without withholding data
The instinct to prevent reverse-engineering by sharing less is usually the wrong one. Education, governance and defined processes are the better answer. Open-reporting programmes, for example, can report by confidential sales zones or PMAs unique to each participant rather than by fine public geography, which makes the data far harder to reverse-engineer without reducing its usefulness.
Process closes the remaining gap: a standard request form for any zone change can carry, as its first condition, an explicit commitment not to reverse-engineer the data. Strong contracts and a clear code of conduct still rely on good ethics underneath them, which is why the architecture that enforces the rules matters as much as the rules themselves.
Where competition law fits
Well-governed programmes are designed around a clear footing: PowerStats collects and distributes historical unit-based data, reported after the fact. Antitrust attention concentrates on forward-looking, collusive information - price fixing and future production plans - which is exactly what a properly run programme keeps off the table. The behavioural line is bright: no direct competitor contact through the programme and no pricing discussions, a point a market-leading participant makes plainly in why market leaders should still share their data.
Regulation differs across the hundreds of jurisdictions these programmes touch, and how the law applies to any given participant is something only that participant, with its own advisers, can determine. Good governance makes sure the spirit as well as the letter of a programme meets the regulator's guidelines - it never substitutes for a participant's own legal review.
How trust is maintained over time
Trust is easier to lose than to build, so the governance has to hold every month, not just at launch. Neutral administration, consistent rules, one independent standard both sides of a relationship can rely on - the "apples with apples" an independent provider guarantees, as an experienced OEM-side consultant puts it in an independent insight: trust and OEM-dealer relationships - and a security record participants can verify are what keep contributions flowing year after year.
Frequently asked questions
What do other participants see of our data?
It depends on the reporting model the group has chosen. In closed reporting, other participants see only an aggregated total that includes you, never your individual figures. In open reporting, participants see each other's brand-level results, and in delayed reporting brand-level detail opens once each month passes the agreed window. The model is chosen by the participants themselves, by consensus.
Can we advertise our market share from a data sharing programme?
Generally, no. Shared data is for internal use, and market share claims that reference the programme are prohibited in external communications even when the position is genuinely true. Promotional use is one of the most common breaches. Your association's rules may guide this further.
Is sharing sales data through an industry programme collusion?
A properly governed competitive data sharing programme is built to sit well clear of that line. The data is historical and unit-based, reported after the fact; participants have no direct contact with each other through the programme and pricing is never discussed. Because competition law differs by jurisdiction, each participant makes its own determination of eligibility with its own advisers before joining.
What happens if a participant breaks the rules?
A well-run programme has a documented incident-response process: education first, then a formal written warning, with exclusion only as a last resort under objective criteria. After any breach, a prompt and transparent memo to members protects the trust the programme runs on.
