We view customizability along two dimensions, namely, configurability and extensibility. In essence, Configurability is making choices along pre-defined dimensions of variations, and Extensibility is adding a new variant along an existing dimension of variation and/or adding a new dimension of variation.

We will be extending the existing 'building block' abstraction (with bi-directional mapping to feature models) and building on top of Jet technology to address these needs. Modeling variability of real-life successful enterprise applications will be an important case study for this work and will also help in its migration to open platforms, if desired.

The ultimate goal is to organize TCS business products as a family of product-lines and support their delivery in the form of a repository of business components and a customization toolset that end-users can use with little external help.
