5 software design principles

Enter the characters you see below Sorry, we just need to make sure you’re not a robot. This article needs additional citations for verification. Software design is the process by which an agent creates a specification of a software artifact, intended to accomplish goals, using a set of primitive 5 software design principles and subject to constraints. Software design usually involves problem solving and planning a software solution.

This includes both a low-level component and algorithm design and a high-level, architecture design. Software design is the process of envisioning and defining software solutions to one or more sets of problems. The main difference between software analysis and design is that the output of a software analysis consists of smaller problems to solve. Additionally, the analysis should not be designed very differently across different team members or groups. In contrast, the design focuses on capabilities, and thus multiple designs for the same problem can and will exist.

Software design is both a process and a model. The design process is a sequence of steps that enables the designer to describe all aspects of the software for building. Creative skill, past experience, a sense of what makes “good” software, and an overall commitment to quality are examples of critical success factors for a competent design. The design process should not suffer from “tunnel vision. A good designer should consider alternative approaches, judging each based on the requirements of the problem, the resources available to do the job.

The design should be traceable to the analysis model. Because a single element of the design model can often be traced back to multiple requirements, it is necessary to have a means for tracking how requirements have been satisfied by the design model. The design should not reinvent the wheel. Systems are constructed using a set of design patterns, many of which have likely been encountered before.

These patterns should always be chosen as an alternative to reinvention. The design should “minimize the intellectual distance” between the software and the problem as it exists in the real world. That is, the structure of the software design should, whenever possible, mimic the structure of the problem domain. The design should exhibit uniformity and integration. A design is uniform if it appears fully coherent. In order to achieve this outcome, rules of style and format should be defined for a design team before design work begins. A design is integrated if care is taken in defining interfaces between design components.
