DAR Requirements Analysis Document
The requirements analysis document (DAR) is a technical document that details the functional and non-functional requirements of a software system. It is a fundamental document for any software development project, as it provides a clear and shared basis for understanding user needs and for defining the characteristics and performance of the system.The DAR is usually produced by the requirements analysis team, which is responsible for collecting, analyzing and documenting the system requirements. The document is then used by the design team to define the architecture and functionality of the system, and by the development team to implement the system according to the requirements.Structure of the DARThe DAR is usually structured to provide an overview of the system requirements, followed by a detailed description of each requirement. The overview should include general information about the system, such as its purpose, users, and target platforms. The detailed description of each requirement should include the following elements:Requirement name: a short, concise name that identifies the requirement.Requirement description: a detailed description of the requirement, including its purpose, functionality, and performance.Requirement priority: an assessment of the priority of the requirement, based on its importance to users and to the success of the system.Requirement status: the status of the requirement, whether completed or approved.Functional requirementsFunctional requirements define the functionality that the system must provide. They can be divided into basic requirements, which are essential for the operation of the system, and optional requirements, which can be added to improve the functionality of the system.Non-functional requirementsNon-functional requirements define characteristics of the system that are not directly related to its functionality. They may include performance, reliability, security, usability, and interoperability requirements.Tips for writing an effective DARThe DAR must be written clearly and concisely, so that it is easily understandable by all interested parties. The document must also be complete and accurate, so that it provides a solid basis for system development.Here are some tips for writing an effective DAR:Use simple and direct language. Avoid the use of technical terms or jargon that may not be understood by all stakeholders.Provide examples and illustrations. Examples and illustrations can help clarify requirements and make them easier to understand.Use a consistent structure. The structure of the document should be consistent, so that the information is easy to find.Review the document carefully. Before distributing the document, review it carefully to ensure that it is complete and accurate.ConclusionsThe DAR is a fundamental document for any software development project. An effective DAR can help ensure that the system meets user needs and is developed efficiently and productively.

Structure of the DAR
The DAR is usually structured to provide an overview of the system requirements, followed by a detailed description of each requirement. The overview should include general information about the system, such as its purpose, users, and target platforms. The detailed description of each requirement should include the following elements:
- Requirement name: a short, concise name that identifies the requirement.
- Requirement description: a detailed description of the requirement, including its purpose, functionality, and performance.
- Requirement priority: an assessment of the priority of the requirement, based on its importance to users and to the success of the system.
- Requirement status: the status of the requirement, whether completed or approved.
Functional requirements
Functional requirements define the functionality that the system must provide. They can be divided into basic requirements, which are essential for the operation of the system, and optional requirements, which can be added to improve the functionality of the system.
Non-functional requirements
Non-functional requirements define characteristics of the system that are not directly related to its functionality. They may include performance, reliability, security, usability, and interoperability requirements.
Tips for writing an effective DAR

Here are some tips for writing an effective DAR:
- Use simple and direct language. Avoid the use of technical terms or jargon that may not be understood by all stakeholders.
- Provide examples and illustrations. Examples and illustrations can help clarify requirements and make them easier to understand.
- Use a consistent structure. The structure of the document should be consistent, so that the information is easy to find.
- Review the document carefully. Before distributing the document, review it carefully to ensure that it is complete and accurate.
Conclusions
The DAR is a fundamental document for any software development project. An effective DAR can help ensure that the system meets user needs and is developed efficiently and productively.
