Final answer:
An analyst advising a customer of a potential late arrival in advance is engaging in proactive communication and preventive strategy, which reflects professionalism and a dedication to customer service.
Step-by-step explanation:
An analyst calling a customer to say that he is going to be late arriving at the customer's site, before he is late, is an example of proactive communication. This demonstrates the analyst's commitment to professionalism and customer service by tackling potential issues before they become problems. It is akin to observing and learning from experiences as an employee who starts leaving home earlier to avoid being late or planning travel in advance to account for possible traffic.
By proactively communicating, the analyst is also employing a preventive strategy to manage customer expectations and maintain trust. This approach is beneficial in various business scenarios, such as in market research where timely feedback is important, or in personal life when managing schedules and commitments.
