A credit card company needs to implement the functionality for a service agent to process damaged or stolen credit cards. When the customers call in, the service
agent must gather many pieces of information. A developer is tasked to implement this functionality.
What should the developer use to satisfy this requirement in the most efficient manner?
Option A: A screen-based flow is ideal for gathering multiple pieces of information from the user interactively. It provides a declarative way to guide the service agent through the process step-by-step.
Not Suitable:
Option B: An approval process is for routing records for approval, not for gathering user input.
Option C: Apex triggers are for automation, not for interactive user input.
Option D: A Lightning Component could work but requires custom development, which is less efficient than using flows.
