Customer experience is the factor that the sales representative can focus on to win the customer first and support their sales quota long term, because it is the sum of all the interactions and emotions that the customer has with the sales representative and the company throughout the sales cycle and beyond. A positive customer experience can lead to customer satisfaction, loyalty, retention, and advocacy, which can result in repeat purchases, referrals, and testimonials. Product evangelism and maximizing opportunities are not the best answers, because they are more focused on the sales representative’s own goals and interests, rather than the customer’s. Product evangelism is about promoting the product’s features and benefits, but it may not address the customer’s specific needs or challenges. Maximizing opportunities is about increasing the contract value or volume, but it may not align with the customer’s budget or expectations. References: Certification - Sales Representative - Trailhead, [Sales Rep Training: Prepare Your Team to Sell Successfully - Trailhead]
