s to achieve more advanced object-oriented (OO) software. The motivation is to achieve a higher level of OO features, such as * Stability: the objects will be stable over time and will not need changes *

Reusability In computer programming, reusability describes the quality of a software asset that affects its ability to be used in a software system for which it was ''not'' specifically designed. An asset that is easy to reuse and provides utility is conside ...

: the objects will need the least amount of maintenance

Principles

The design tries to make use of common sense while guiding through the process of SM based design. It will need minimum amount of rampup time for people to understand new applications and objects once the process and methodology is kept in mind. The stability model is built using three main concepts - * Enduring business themes (EBT) * Business objects (BO) * Industrial objects (IO)
