Want to develop a new product? Where do you start?

I’ve been working with a lot of companies lately that have never developed a new product from scratch. They all seem to have the same question – “Where do I start?”

The answer is always the same – with requirements, and by requirements I don’t mean a bullet list of features, although that’s a start. By requirements, I mean detailed requirements of what you want the product to do and how it should behave in every situation. Error conditions are one thing that’s typically forgotten. Requirements are also not necessarily functional, for example, the maximum (or target) manufacturing cost is a common, and commonly overlooked, requirement for an embedded system. They say the “devil’s in the details.” In this case, that’s true.

The first question clients have (well, maybe it’s not the first, but it’s the big one everyone wants to know) is “how much will this cost?” Without the kind of detailed requirements I’m talking about, it’s impossible to give any kind of meaningful estimate. That’s why we’ve had such great success creating an initial engagement that delivers requirements and a rough estimate of time and cost. This initial engagement typically lasts between a week and a month, depending on the scope and complexity of the project and gives the client accurate information that they can use to make decisions. We usually find areas of trade-off, like features that could be in a future release, and can balance the client’s time to market and budget needs.

So remember, next time you have a new product you’re developing. Details, details, details!
