SOR, or Statement of Requirements, refers to a document that outlines the specific needs and expectations for a project or task. It serves as a roadmap for the project, providing clear and concise guidelines for what needs to be accomplished and how it should be done. SORs are commonly used in business and government settings, but can also be utilized in personal projects. They are essential for effective planning and communication, ensuring that all parties involved are on the same page and working towards a common goal. A well-crafted SOR can lead to successful and efficient project completion, while a poorly written one can result in confusion and delays.
