Method and system for selecting software module from gradation directory

Provided is a method for generating an on-demand, custom runtime solution to a user or business's computing needs. A library of software components corresponding to different computing tasks of a business situation is created. Each software component is associated with one or more meta descriptors. The software components and related meta descriptors are managed by means of a software component meta management system (SCMMS). Based upon customer, input, various components are selected, or filtered, for incorporation into a business runtime solution. In addition to the user input, user queries are feedback into the SCMMS so that the SCMMS accumulates knowledge about the customer's usage. The knowledge is then employed to facilitate and improve the generation of future runtime solutions for both the customer and other customers.
