ITIL 4 Foundation — Question 304

Which is an external input to the service value chain?

Answer options

• A. The 'improve' value chain activity
• B. An overall plan
• C. Customer requirements
• D. Feedback loops

Correct answer: C

Explanation

Customer requirements are considered an external input to the service value chain because they originate from outside the organization and guide service development. The other options, such as 'improve' activities, overall plans, and feedback loops, are more about internal processes and adjustments rather than external inputs.
