Have you written large documents like technical specifications that describe the entire system?

Yes, as a systems analyst, it is often necessary to create large documents such as technical specifications (TS), which describe the entire system in detail.

These documents usually contain:

• Goals and objectives of the project
• Functional requirements
• Non-functional requirements (performance, security, etc.)
• Description of the architecture and components of the system
• Usage scenarios and business processes
• Constraints and assumptions

The document should be as clear and comprehensive as possible so that developers, testers, and other project participants have a unified understanding of the requirements and expectations.
