Product development needs evidence on both, at a point when that evidence can still change the work. Article on Product development, 3 min read Reviewed by [Anne Lacey, Founding Partner](https://antedote.com/why-antedote/#partners) on October 27, 2026. Published October 27, 2026. A product can have a persuasive promise and an experience that makes the promise difficult to reach. It can also be easy to use without offering a benefit people care about enough to choose it. Whether a product’s promise appeals and whether its first use works are separate questions, and evidence about one says little about the other. Product development needs both, at a point when the evidence can still change the work. The challenge is deciding what the next piece of research needs to establish. Imagine a connected accessory that offers a valuable new capability. Before someone experiences the benefit, they have to understand where it fits, set it up and feel confident that it is working. A concept description may communicate the eventual value very well. It may tell the team little about those first encounters. Watching someone complete setup successfully would not establish that the proposition is compelling enough to buy, either. The two pieces of evidence answer different questions. Judging a product on its promise and judging it in use can lead to different answers. In [University of Maryland research](https://www.rhsmith.umd.edu/news/feature-fatigue-research-proves-simpler-products-are-better-manufacturers-advised-lose-extra) on what its authors called feature fatigue, 66 percent of people choosing on features alone preferred the model with the most features. In a later study, “when people actually had a chance to use the product, 56 percent preferred a simpler model.” A product team can have several uncertainties at once, even when a project is described as being at a particular development stage. The research needs to address the uncertainty with the most consequence, whatever standard test happens to be next on the schedule. ## Different products can need different evidence at the same time A consumer technology company had four accessories at very different stages of development, each with its own question. For the next generation of an existing product, the question was which value proposition should lead, and for whom. For a new device, it was who would value it and how to explain its benefit. For two prototypes, it was whether people could set them up and trust them first time. Which proposition should lead called for a quantitative test across audiences. Whether people could set up a prototype first time called for watching them try. One program matched a method to every question, and it didn’t assume that the evidence needed for an audience decision would also answer questions about first use. Each answer reached the product and marketing teams at the point in development it was meant to inform. The work is described in [Four accessories in development, each with its own question](https://antedote.com/explore-our-work/four-accessories-in-development/). ## What a positive result would justify Before commissioning research, it helps to be clear what a positive result would justify: further development of the proposition, a choice between feature combinations, a change to setup or investment in a more realistic prototype. That doesn’t mean every exploratory project must begin with a fixed decision. Sometimes the task is to understand the experience well enough to find the right development question. The point is to keep the interpretation in proportion to the evidence. High interest in an idea may justify exploring it further. It does not establish that the technical benefit can be delivered, that the experience is workable or that the commercial model is attractive. In the same way, difficulty with a prototype may point to something to improve. On its own, it is no reason to abandon the proposition. ## What people are responding to Early product material can leave a great deal to the imagination. People may supply their own assumptions about performance, compatibility, effort or price. Those assumptions can be part of what makes a concept appealing. As development progresses, it becomes possible to replace some of those imagined conditions with a more concrete experience. The purpose is to learn where the proposition still persuades, where the product needs work and where the original promise may need rethinking. A team should be able to tell the difference between enthusiasm for an idealized benefit and confidence in the offer it can actually make. That distinction allows research to be encouraging without becoming a premature certificate of success. There is no single test that closes every question. Good development work keeps the promise, the experience and the business ambition connected. It asks what must become true for the next investment to make sense, then looks for evidence capable of informing that judgment. ## Read next - *Article* · 4 min read ### [AI can make an idea look finished before the thinking is.](https://antedote.com/thinking/ai-concept-development-polish/) AI can make a concept tangible sooner.
