PSI, From Custom Developed Application to Domain Specific Framework

This report describes the experience we had at OO Partners with the design and implementation of PSI, a custom developed planning application for a TV-station, and its evolution into a complete domain specific framework that has been successfully installed at several TV-stations in Europe.

We report on our experience with object technology, in particular with Smalltalk, and on the barriers we encountered in designing and implementing the PSI framework. Furthermore, we expound on how we have organised ourselves to increase the productivity of our team and to obtain higher quality software that is more adaptable and reusable.

Due to our project approach, OO Partners has built up solid domain knowledge, which is the key to our success with PSI. Gathering this domain knowledge constitutes the major part of the investment. Frameworks are essential to leverage this investment. This experience also applies to other vertical markets.
