How many different inputs are there?
Somewhere between 1 and 1,000,000 different inputs. At a minimum, you need to describe your project with a size in Source Lines of Code (SLOC) or Function Points, so you need at least one input (!). But, for each component, there are 50 to 100 different items you can set (costs, cost drivers, maintenance cost drivers, etc.), and in Costar 7.0 you can create thousands of components, so in theory, there are hundreds of thousands of possible inputs. In practice, you’ll probably set only a handful of parameters for each component. Subcomponents in Costar can inherit attributes from their parent components, so if you set the Programmer Capability cost driver to Very High for the top level component, that value will be inherited by all subcomponents (unless overridden by a different value in a particular subcomponent). That simplifies life.
