Product Development
Product development is really the process of narrowing, not building. You start with an idea that feels wide open — "a functional snack," "a better beverage" — and every stage is really just cutting away the versions of it that don't survive contact with reality: taste, cost, shelf life, how it's actually made at scale, whether people reach for it twice.
The uncomfortable part is that most of what kills a food idea isn't the concept, it's something unglamorous downstream — the texture falls apart after two weeks in the fridge, the "natural" version costs four times what people will pay, the flavor that tested well in a small tasting doesn't hold up once it's mass-produced. None of that means the idea was wrong. It means the idea hadn't been pressure-tested yet, and pressure-testing early and cheaply is the whole point of development — better to find the flaw in a kitchen batch than after a factory run.
There's also a sequencing instinct worth having: taste and format usually need to be right before health claims and positioning are worth investing in. A product can be functionally impressive and still fail if it's not something people actually want to eat again. So development tends to work best when it protects the craving first, and treats everything else — the science, the packaging, the story — as things built around that, not substitutes for it.
The last thing to know is that "done" isn't really a fixed point. Most successful products keep changing quietly after launch — a tweak to texture, a shift in portion size, a new flavor that responds to how people are actually using it. Development doesn't really end at launch, it just changes speed.
