What type of feedback is classified as Subjective during a customer review meeting?

The classification of feedback as subjective hinges on its reliance on personal feelings, opinions, or experiences rather than on objective data or measurable metrics. In the context of a customer review meeting, customer satisfaction ratings offer a personal assessment of how the customer feels about the service or product they received. These ratings reflect the customer's individual perspective and emotional connection to the service rather than hard statistics or quantifiable outcomes.

In contrast, the other options are grounded in objective data. For instance, the percentage of marketing emails opened provides measurable insight into engagement levels, while the number of successful project implementations and retention rates are definitive metrics showcasing performance outcomes and customer loyalty. These statistics do not rely on personal feelings and instead reflect concrete results, making them objective rather than subjective. Thus, customer satisfaction ratings stand out as the choice that embodies the subjective nature of feedback in a review setting.
