A technical specification document serves as a comprehensive guideline outlining the requirements, functionalities, and design aspects of a technical project. It details key elements such as system architecture, interfaces, performance metrics, and compliance standards to guide the development team. By establishing clear expectations and criteria for success, the technical specification serves as a reference point throughout the project lifecycle. Stakeholders can use this document to ensure that all team members are aligned with the objectives and design decisions. Ultimately, it enhances communication and reduces the risk of misinterpretation during implementation.
