The standardized structure imposed by the software development market leaders are the development systems or processes strictly implemented in order to create a uniform development system anywhere in the world.
To understand software development systems fully a person would require a large amount of knowledge in the field of software engineering. However, if you are contemplating the leap into the unknown that is software development, it always helps to know some of the basics, even if you will not be heavily involved in the actual development. With this knowledge you will have in your armory the means to assess the stability and standards of the software being developed.
Today, there are three development systems that need consideration. Firstly is the Waterfall Process, secondly the Iterative Process and thirdly the Formal Method. The best known and most widely recognised among software developers is the Waterfall Process.
The waterfall model called as such because the manner in which the software development is executed can be likened to that of a waterfall: the eight (8) basic activity processes or steps are done from top to bottom like a falling waterfall. These eight (8) basic processes or steps are: (1) Requirement Analysis, (2) Specification, (3) Software Architecture, (4) Implementation (Coding), (5) Testing, (6) Documentation, (7) Software Training and Support, and (8) Maintenance.
In many software development systems, these 8 steps are interchanged and not all are done within the Waterfall Model. Some argue that this model is the most stable and suited model available, despite it’s age! This is due to the ease of determining problems or bugs within the system, even as early as the specification requirements analysis and before any programming or coding begins. Through experience, a programmer will normally find it much harder to insert a fix into code that has already been written and finished, than it is to code that fix as part of the solution in the first place.
