Method and system for providing tooling instructions through parameterization as an aid for software application development

An invention is disclosed for a programming method and system of implementing parameterization of data types and/or categories to convert an example "instance" of using a software application into an actual product of program use by customizing the example to make it suitable for user needs. A parameter modeling component along with a parameterization component and an instantiation component are used to create parameterized example instances ("p-instances") and tooling instructions are then invoked to customize a "p-instance" into a real instance reflecting creation of a document or file or other program artifact (i.e., data product) resulting from actual use of the software application.
