Define the System Scope

Once the information products have been described, you can begin to define the scope of the entire system. This involves determining what data to acquire, when it will be needed, and the data volumes that need to be handled. This includes assessing the probable timing of the production of the information products. It may become clear that it will be possible to use one input data source to generate more than one information product, and this can now be built into your development program. Each refinement helps clarify your needs and increases your chance of success.
