Which of the following processes provides guidance to the system designers and form the basis of major events in the acquisition phases, such as testing the products for system integration.
Click on the arrows to vote for the correct answer
A. B. C. D.A.
The process that provides guidance to system designers and forms the basis of major events in the acquisition phases, such as testing the products for system integration, is functional requirements (option B).
Functional requirements describe the system's intended behavior and specify what the system should do in terms of inputs, processing, and outputs. They are critical to the development and acquisition of systems because they help ensure that the system meets the needs and expectations of the users, stakeholders, and other requirements.
Functional requirements are typically derived from the operational scenarios (option A), which describe how the system will be used in its intended environment. Operational scenarios provide a context for understanding the system's purpose, goals, and objectives and are used to identify the key functional requirements that the system must satisfy.
Human factors (option C) are also important in system development and acquisition because they consider the user's needs and limitations. Human factors engineering ensures that the system is designed to be safe, effective, and easy to use.
Performance requirements (option D) specify how well the system must perform, in terms of speed, throughput, capacity, availability, and other metrics. Performance requirements are important to ensure that the system can meet its intended operational needs.
In summary, while all of the options listed are important in system development and acquisition, functional requirements provide guidance to system designers and form the basis of major events in the acquisition phases, such as testing the products for system integration.
