Stability Model (SM) is a method of designing and modelling software. It is an extension of Object Oriented Software Design (OOSD) methodology, like UML, but adds its own set of rules, guidelines, procedures, and heuristics to achieve a more advanced Object Oriented software.
The motivation is to achieve a higher level of OO features like -
- Stability - it means much of the objects will be stable over time and will not need changes.
- Reusability - it means majority of the objects can be reused for various kind of applications.
- Maintainability - this is an OO feature which applies more for SM because the objects will need least amount of maintenance.
Examples
The Stability Model has been seen and used in an array of different use-cases. One of such is in the Bravery model, where AnyEvents such as 9/11 terrorist attacks may cause AnyImpact such as economic impacts, psychological impacts, and physical/health impacts.[1]
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)
History
The SM method of OOSD was formulated by Dr Mohamed Fayad. He has been the editor in chief of the Computer Magazine of the IEEE for many years. He has taught OOSD in two US universities and has written and currently writing few books on this subject.
