Final answer:
The structured step-by-step software development methodology involves a design process that is sequential yet iterative. It includes stages such as design, prototyping, and testing, and it requires repetitive cycles for continuous improvement. This methodology also considers human-software interactions and decision-making within complex automated systems.
Step-by-step explanation:
The subject in question is a software development methodology, which is a structured step-by-step approach for developing information systems. This methodology involves several stages such as detailed design, prototyping, testing, and refinement. These stages are typically completed in sequence but often require multiple iterations for continuous improvement. This iterative approach includes human-software interactions and decision-making processes as workers interact with the system being developed. Additionally, the design process sometimes adopts a spiral approach, further highlighting the repetitive or cyclical nature of the development process, where each phase is revisited as needed to refine and improve the system.
Looking into historical aspects, the battle between open resources and commercial interests in computing has shaped how software development methodologies have evolved. Operating systems like UNIX started as more open but became commercialized over time. This relates to the methodology's adaptability and its role in large-scale processes and complex automated systems.
Referencing the LibreTexts™ engineering design process, software development involves various phases that are conceptually sequential but are often revisited, illustrating the method's adaptability and its requirement for a continuous development view. After identifying the need for improvements upon testing and evaluation, the development team returns to earlier stages, completing project tasks in repetitive cycles until the desired results are achieved.
