Resumen
Since the early 1980s, object-oriented (OO) frameworks have demonstrated that OO programmers can encapsulate a reusable, tailorable software architecture as a collection of collaborating, extensible object classes. Such frameworks are particularly important for developing open systems in which not only functionality but architecture is reused across a family of related applications. Unfortunately, the design of frameworks remains an art rather than a science because of the inherent conflict between reuse packaging software components that can be reused in as many contexts as possible and tailorability designing software architectures that are easily adapted to largest requirements. To cope with this conflict, well-designed OO frameworks must provide a clean conceptual framework that clearly identifies hot spots where tailorability is necessary and desirable and specifies framework contracts that formalize exactly which parts of the framework are to be reused. Tailorable frameworks are Particularly useful for the construction of so-called open systems.

Resumen
As a provider of broadcast planning Software for television stations, programmers have to create highly customized software while maintaining the quality standards of an off-the-shelf product. Framework technology plays a strategic role in our business, because there are many similarities in the complex broadcast planning processes of different stations, yet a standard product would satisfy only 70% to 80% of the needs of a typical station. Thanks to frameworks, customers can be offered a standard product that is easily customizable by a small team of software engineers in a cost-effective way. Moreover, the adaptive nature of frameworks provides another advantage; like any other business, television stations need to respond to new and rapidly changing market opportunities. They are faced with rapidly evolving hardware and rapid evolution of their product. These changes require more malleable software. For broadcasters, the ability to cope with change more efficiently than from similar off-the-shelf applications results in a competitive advantage.
