This article is the first in aytm’s Innovation Intelligence series, each of which explores a different stage in the innovation research funnel. These articles summarise elements of the Product Innovation curriculum in the aytm Lighthouse Academy.

Most product teams understand that consumer research matters. The debate is rarely about whether to do the research. It’s about when. Many organisations default to testing only when they have something polished to show: a developed concept, a prototype, or a near-final design. By that point, significant time and budget have already been committed, and the research becomes a validation exercise rather than a decision-making tool.
The innovation funnel actually starts much earlier than that, and the teams that understand this have a structural advantage over those that do not.
What the Innovation Funnel Looks Like
The full innovation process moves through six stages: idea generation, idea screening, early-stage concept testing, concept refinement, late-stage concept testing, and launch. Most market research activity is concentrated in the later stages. Idea screening sits between raw ideation and structured concept development, and it’s where many organisations have a significant gap.
This matters because the decisions made at the idea screening stage shape everything that follows. Which ideas get developed? Which ones get resources? Which ones get shelved before anyone invests in copy, design, or prototyping? Without a structured screening process, those decisions get made internally, often based on hierarchy, familiarity, or whoever makes the strongest case in a meeting.
The Cost of Skipping Early Research
Consider a practical example. A food brand generates 20 new product ideas. Without early screening, the next step is developing full product concepts for all of them, likely including detailed descriptions, visuals, and positioning statements. That work involves multiple cross-functional teams across marketing, R&D, and creative, and it can take weeks before a single consumer has seen anything. Then comes prototyping, which is even more expensive.
Based on industry benchmarks, developing a basic product concept (text plus a simple visual) runs approximately $1,500 per concept. For 40 ideas, that’s around $60,000 and six weeks of development time. Running an idea screen first, at a fraction of that cost, can reduce the field to the six strongest candidates before any of that work begins. And the savings on a 40-idea project can exceed $40,000, with weeks cut from the timeline.
That isn’t just a cost argument but also a speed argument, because faster decisions about which ideas to pursue mean a faster time to market. In competitive categories, that can matter as much as the product itself.
What Idea Screening Actually Does
Idea screening is a research method used to evaluate a large set of early-stage ideas and identify the most promising ones for deeper development. At this stage, ideas don’t need to be polished. They need to be clear, consistent, and sufficiently different from each other.
The method best suited to idea screening is a MaxDiff (Maximum Differential) exercise. Rather than asking respondents to rate each idea individually on a scale, MaxDiff requires them to make trade-offs. From a set of three to five ideas shown at a time, respondents indicate which is most appealing and which is least appealing. This process repeats across multiple screens, and the resulting data provide a clear rank order of ideas, with a measure of how strongly each is preferred relative to the others.
The practical output of this is a ranked list of ideas with statistical confidence behind it. Not gut instinct. Not committee consensus. Teams know which ideas consumers respond to, and by how much, before committing to the expensive work of concept development.
Where Idea Screening Sits in the Bigger Picture
It’s also worth being clear about what idea screening does and does not deliver. Idea screening provides prioritisation: a relative ranking of the ideas tested. It gives teams data-driven confidence to make the next decision, but it doesn’t guarantee market success, tell you how to price a product, or evaluate manufacturing feasibility. It’s an early filter, not a final verdict.
That distinction matters when managing stakeholders because the output of an idea screen is a starting point for concept development, not a substitute for it. The ideas that rank well still need to be developed, tested more rigorously, refined, and validated before launch. What screening does is ensure that all of that subsequent work is directed at ideas that already show consumer potential, rather than at ideas that seemed strong in a brainstorming session.
The Structural Shift This Requires
Running research earlier in the process requires a different mindset about what research is for. When teams test only late-stage concepts, research is being used to confirm direction. When research starts at the idea screening phase, it’s being used to set direction. The former is lower risk in the short term. The latter reduces risk across the entire development cycle.
Teams that incorporate idea screening into their standard innovation process also accumulate the added value of a growing body of knowledge about which kinds of ideas resonate with their target consumers and which do not. That informs future ideation, turning early-stage research from a one-off project into an ongoing source of competitive intelligence.
Getting Started
What’s more, the barrier to entry for idea screening is lower than many teams expect. Ideas at this stage can be tested as simple text descriptions, with research completed in days, and learning that is immediate and actionable.
For teams looking to build this capability, the aytm Lighthouse Academy includes a dedicated course on Idea Screening 101 that covers the full process, including how to prepare your list of ideas, how to set up a MaxDiff study, how to interpret the results, and how to communicate findings to stakeholders. It also sits within a broader curriculum covering every stage of the innovation funnel, from early screening through to launch.
If your organisation is routinely creating full product concepts before any consumers have seen the ideas, the innovation funnel is starting too late. Shifting even one stage earlier can reduce waste, accelerate timelines, and increase the odds that the ideas you develop are the ones worth developing.
