Very Rapid Application Development (VRAD)

We can now build many systems faster than anyone ever imagined, using the right techniques, tools, and management. In fact, the hardest thing to do is to convince people that high-quality systems work doesn't have to take forever. The Ken Orr Institute has developed within its Warnier/Orr Methodology an approach to building and testing systems that we call Very Rapid Application Development. This approach incorporates methods and tools that automatically generate database designs and prototypes that users can actually see, touch, and play around with.

After nearly thirty years in the systems development business, KOI has become convinced that it is "easier to refine than it is to define." Most users don't really know what they want their systems to do until they see it. This is why COTS packages are so popular. Users and managers can see them in operation, so it becomes much easier to understand what the systems can do.

KOI's VRAD approach is built around a number of ideas, getting a good jump at the systems requirements, defining a solid architecture for the entire system, and then breaking the system into a set of "doable subprojects" that can be executed rapidly and one at a time. Each piece is then done through a series of user available prototypes. These prototypes, in turn, allow the users to understand exactly what they are going to get before they get it.

VRAD is also built around the concept of output-oriented design and flexibility. Too often, inexperienced systems developers on their first project attempt to build too much adaptability into their systems in the vain hope that "this system will never have to be modified." The price of such adaptability is often huge amounts of time wasted guessing about the future. KOI has found that every time you guess, you have a better- than- average- chance of guessing wrong. What VRAD does is allow us to build just what you need right now, using tools such as GeneXus that have the ability to redesign and regenerate the entire system when business or technology changes require new systems approaches.
