What is the main problem with the system description structure - Incorrect separation of functions - System requirements are incomplete - System boundaries are not described clearly enough - Requirements description is unclear - Requirements for functions are described unclearly - System functions are described incompletely

The main problem with system description structure is often related to insufficiently clear definition of system boundaries and functions, which leads to incomplete and unclear requirements.

The most critical among the listed is:

• System boundaries are not clearly defined — without clear boundaries, it is difficult to determine what is part of the system and what are external components, leading to confusion and incomplete requirements.

This, in turn, causes problems with delineating functions and clarity of requirements. If boundaries are not defined, functions may overlap or remain undescribed, and requirements may be incomplete or unclear.

To address this, it is important to:

• Clearly define what is included in the system and what is not.
• Clearly describe functions and requirements within these boundaries.
• Ensure completeness and unambiguity of the description to avoid misunderstandings during development and testing.
