Compliance & Auditing
Like security, compliance and auditing are vital for the success of any project. Auditing can help you objectively evaluate the technical specification document, identify gaps, and facilitate continuous improvement.
You can also run timely audits to ensure the specifications manual meets the specific quality requirements. It would ensure that the teams adhere to industry regulations and conduct proper auditing or certification processes.
What Is the Difference Between Technical Specification vs. Functional Specification?
While a technical specification document describes how the product will be implemented, a functional specification document focuses on product behavior from the users’ point of view.
Here are some fundamental differences between technical specifications and functional specifications documents:
Both documents are essential and work together to provide a comprehensive understanding of the product, addressing both technical and functional aspects.
| Specification Type | Technical Specification | Functional Specification |
| Purpose | Define the system’s technical requirements | Describe the system’s functional requirements |
| Focus | Hardware, software, and infrastructure | User interactions, features, and behavior |
| Scope | Technical aspects of the system | User requirements and system functionality |
| Deliverables | System architecture, APIs, protocols | Use cases, user stories, functional requirements |
