Software Development Methodology (SDM) is the process of creating software through code generation and tool use. SDM frameworks organize the process and establish best practices. The “waterfall” model is a basic example, while the spiral model captures development phases in a unified process.
Software Development Methodology (SDM) is a means by which a program is created through the generation of code and the use of different tools. This basically refers to the process itself and how it is managed, to ensure that development is completed on time and within a reasonable budget. There are several forms that software development methodology can take, depending on the nature of the program being created and the tools being used. In general, however, SDM is governed by the need to ensure a division of tasks into manageable elements and a process that goes through many expanding iterations.
There are many different frameworks that can be used within a software development methodology, which are typically employed to organize the process of creating a new program. Multiple frameworks can be used together to create a single SDM, so numerous methodologies can be combined into an SDM family. Using a software development methodology often establishes and encourages best practices in building new software for a team of developers. Without an SDM to look forward to during development, the process can easily become chaotic and waste both financial resources and time.
One of the most common and simple types of software development methodology is referred to as the “waterfall” model. Before this SDM can be used, specific goals must be established for a particular process, and the entire development cycle must be broken down into several elements. It is then possible to approach a single element and walk it through a series of steps, each visualized as a downward procession creating the concept of a “waterfall”. This type of software development methodology is no longer used in many situations as newer methods have replaced it, but it continues to serve as a basic example of how an SDM should be structured.
The spiral model has become a popular software development methodology because it captures two important elements of the process in a single view. In general, a spiral is a single line starting at the center, moving outward in concentric rings that get larger but pass through the same circular shape. This is used as a blueprint for software development as each element of a program starts small and increases in size as it is developed. When this happens, it also goes through numerous phases, such as development, evaluation and analysis, through different iterations. All of this creates a single unified process that grows outwardly larger as it moves through repeating steps, much like a spiral.
