Quantus vs. Traditional HEOR Consulting: When to Use Each Model and Why

Not every market access problem is solved the same way. The question is not which model is better in the abstract, but which one fits what your team needs on this specific project. Here is an honest guide to deciding.

There is a temptation, especially in the marketing material of any technology platform, to portray traditional consulting as a slow, expensive dinosaur next to the automated marvel of the moment. It is a caricature, and HEOR and market access teams spot it immediately because they know the real value of good consulting. This article does not make that caricature. Traditional HEOR consulting solves problems that a product-based model does not solve as well, and vice versa. The smart decision is knowing when to use each one.

1. How traditional HEOR consulting really works

The classic HEOR consulting model is, in most cases, structured around projects defined with a scope, a timeline, and a price agreed in advance. The consulting industry broadly has historically used four billing schemes: hourly rate, day or week rate, fixed project fee, and milestone or deliverable billing. Top-tier strategy firms tend to favor the fixed project fee.

The strength of this model is real. A solid HEOR consultancy brings a multidisciplinary team (health economists, epidemiologists, statisticians, physicians with disease-area experience, regulatory specialists) that co-builds an evidence strategy with the client. The value is not only in the deliverable but in the partnership: the intellectual challenge, the pressure of testing ideas against an expert, the reading of the payer context. As one HEOR director puts it about good consulting, the team works as part of the client's team, contributing high-level strategic input and challenge during discussions.

Its limitations are also real. The project model carries a significant entry cost, timelines that can stretch, and a delivery pattern that ends when the project ends. Each new deliverable usually means a new scope, a new negotiation, and a new cost. And quality depends heavily on which specific consultants the firm assigns to your account.

2. How a product-based model like Quantus works

A platform-based model with experts in the loop (which is what Quantus is) inverts the logic. Instead of contracting a closed project each time, expert market access and HEOR knowledge is encoded into a platform that produces the deliverables (dossiers, models, value narratives, field materials, adapted evidence) with automation assistance and human validation.

Its strength is speed, decreasing marginal cost, and scalability: once the knowledge is encoded, producing the second version, adapting it to another country, or updating it costs a fraction of starting from scratch. For a team that needs to repeat, adapt, and update deliverables across multiple products, indications, or markets, that economics changes the calculation.

Its limitation, and it is worth naming it with the same frankness, is that a product-based model does not replace the deep, bespoke strategic partnership that a senior consultancy offers for a genuinely new or ambiguous problem. Automation accelerates the mechanics; it does not substitute for human judgment on a first-time strategic decision with no clear precedent. That is why the serious model keeps the expert in the loop rather than removing them.

3. The decision guide: when each one

Instead of declaring a winner, it is better to map the problem to the model.

Use traditional consulting when:

• The problem is new, ambiguous, or of high strategic complexity, with no clear precedent in your organization. You need bespoke thinking, not a replicable deliverable.
• The decision is extremely high-stakes and one-off (a global launch strategy for your lead asset, an unprecedented price negotiation) where the value of expert partnership justifies the cost and the time.
• You need an external thought partner to push and challenge the internal strategy, rather than to produce a document.

Use a product-based model like Quantus when:

• You need to produce structured and repeatable deliverables (dossiers, economic models, value narratives, field materials) quickly and at a predictable cost.
• The work repeats and adapts: the same asset for several countries, several indications, several agencies, or periodic evidence updates. Here the platform economics are clearly superior.
• Your team has the capacity to validate and apply judgment to the output, but not the time or the sense to invest months of consulting in each iteration.
• The bottleneck is production speed and the cost of scaling, not the absence of a strategy.

4. The point almost no one makes: they are not mutually exclusive

The honest framing is that most mature market access teams do not choose one and discard the other. They combine. They use senior consulting for the high-stakes strategic decision and a product-based model to produce, adapt, and scale the deliverables that strategy requires.

Thinking in terms of "consulting or platform" is a false dilemma. The sensible split is by type of problem: ambiguous, one-off strategy goes to consulting; structured, repeatable, scalable production goes to the platform. A team that puts everything into consulting overpays for replicable work; a team that puts everything into the platform falls short when it faces a genuinely new problem.

5. The question worth asking

Before deciding, the useful question is not "which is better?" but: is this problem unique or repeatable? Do I need bespoke strategic thinking or structured production? Is the bottleneck the lack of strategy or the speed and cost of executing?

If the answer points to unique, ambiguous, and strategic, traditional consulting is still the right tool. If it points to repeatable, structured, and scalable, a product-based model delivers the same thing faster and at lower cost, without sacrificing quality when it keeps expert validation.

At Quantus we designed the platform precisely for that second scenario: to compress the time and cost of producing, adapting, and scaling market access and HEOR deliverables, while keeping expert knowledge and human validation at the center. Not to replace a good consultant's strategic judgment, but so that your team does not spend on each repeatable iteration what it should reserve for the decisions that truly deserve it. The end goal is the same as always: to increase real access and sales of the client's products.
