Software Design - Essay Example The software architecture in place will determine the easiness of change. In as much these â€Å"forgotten problems† are crucial to be addressed, the software development principles have other factors that also need to be addressed. These are the performance, availability, maintainability, security, costs, benefits and schedule. Thus, it is more valuable to achieve a balance rather than focus on only one aspect which in the â€Å"forgotten problems† is the usability factor. The Software architecture is the representation of the software development. It lists all the key modules, their responsibilities, and interactions. It has various representations. It is essential as a good architecture would reduce development time, maintenance costs and improve the quality of product. How does software architecture interact with usability? This can be understood via enumerating all the phases in software development. These are; system formulation, requirement definition, architecture design, detailed design, implementation, system test and deployment. Each of these chapters is critical, and there exist a high level of interactions. The development cycle in place will dictate the level of interactions between these phases. These methodologies are; waterfall cycle, spiral circle, extreme programming and HCI cycle. The feedback mechanisms in these methodologies will show how effective a method is. (Smith & Williams, 2003). The idea is to come up with an architectural pattern that best achieves usability factors. Various patterns can be applied. The Model view controller displays the module responsibilities and their interactions. A good model view controller shows productive interactions. It hides the unwanted aspects of the user interface from the remainder of the application. It provides a means of buffering changes in the user interface from the remainder of the application. It localizes the â€Å"screen-deep† changes to either the
