The lower the coupling, the better the program. The output of software design process is design documentation, pseudo codes, detailed logic diagrams, process diagrams, and detailed description of all functional or non-functional requirements.

The next phase, which is the implementation of software, depends on all outputs mentioned above. It is then becomes necessary to verify the output before proceeding to the next phase. The early any mistake is detected, the better it is or it might not be detected until testing of the product. If the outputs of design phase are in formal notation form, then their associated tools for verification should be used otherwise a thorough design review can be used for verification and validation.

By structured verification approach, reviewers can detect defects that might be caused by overlooking some conditions. A good design review is important for good software design, accuracy and quality. Arnab Chakraborty. Such design documents are usually written by software designers or project managers and are given to the software development team to give them an overview of what needs to be built and how.

It specifies what is possible with the product and how it can be accomplished. Read more: What is a Software Requirements Document. Software design documents are an important way of looping everyone into the process who is involved in the product. It is for everyone to understand what is possible, what is not possible, and the system that will be designed. Design documents are created to coordinate efforts of a large team, give them a stable reference point, and describe all parts of the software and how they will operate.

Software design documents not only help others understand your system and provide documentation for future projects, but it also forces you to think through the entire system architecture.

This ensures you go through every possible roadblock or challenge you might face, thereby exposing all gaps in your thinking. System Overview: Provide a general description and functionality of the software system.

Design Considerations: Describe the issues that need to be addressed before creating a design solution:. Architectural Strategies: Describe the strategies that will be used that will affect the system. System Architecture: This section should provide a high-level overview of how the functionality and responsibilities of the system were partitioned and then assigned to subsystems or components. Detailed System Design: Most components described in the system architecture section will require a more detailed discussion.

Other lower-level components and subcomponents may need to be described as well. Glossary : An ordered list of defined terms and concepts used throughout the document. For creating software design documents, you need a proficient tool that can help you create, share, and collaborate with stakeholders and get work done efficiently. This is where Bit comes in!
