Software Stability Model (SSM) is a radically new and disruptive innovation in the field of software engineering. It is a new way of looking at how any software development effort should be undertaken, different from the approaches that we see today. SSM moves on from the traditional ways of software development where a specific software artifact is developed for every different specific application scenario to an approach that promotes factoring in the needs for the future as well and thus making the software thus developed, ‘stable’ over time, i.e.it need not be changed in a big way repeatedly. SSM provides unique and unified methodology such as high returns on investment, complete and comprehensive development of concurrent, unified, stable, executable functional and non-functional requirements, Ultimate Design, Unified Software Architectures on-Demand, and unified Immune Testing, etc. SSM brings along a list of qualities, such as true unification, stability, scalability, adaptability, extensibility, configurability, maintainability, unlimited reuse, applicability, and more to any software developed in any domain along the lines of this development methodology. SSM also does not draw a hard line of transition between the various steps in any software development methodology. For example, the requirements, design, coding, and testing for any given functionality are done in one go. Such activities can be done for each of the functionalities that have to be included in the software, in a concurrent fashion, thus SSM can also be termed as the Concurrent Software Development Model (CSDM). This presentation is an introduction to the Software Stability Model and how it can be used for any software development undertaking from start to the delivery.
