Which A-series function corresponds to Plans and requirements?

• A. A5
• B. A6
• C. A2
• D. A3

Answer: (A)

The main idea here is that planning and defining what’s needed sets the direction for everything that follows. The A-series function that handles Plans and requirements is the one that explicitly focuses on formulating the plan, identifying the scope, listing the requirements, and establishing acceptance criteria and constraints. This upfront clarity creates the foundation for all later work, guiding decisions, resources, and how success will be measured. Since other functions address execution, verification, or adjustments after planning, they don’t capture the essential planning and requirements phase as clearly.
