A key argument presented in this text is that sales representatives (Account Executives) should be trained to manage their own deals, rather than relying on external Project Managers. This approach can lead to increased deal close rates and customer success, as the Account Executive becomes a single point of contact for the customer throughout the sales process. The value lies not in bringing in professional services teams, but in teaching AEs to effectively project manage their deals. However, simply cutting out Project Managers is not the answer, as they bring technical expertise and internal advocacy that can be valuable. Instead, the key is to integrate project management principles into the sales process, including asking the right questions, working backwards from the customer's goal, establishing clear product capabilities, summarizing the evaluation process, managing time effectively, maintaining motivation with internal champions, and more. By doing so, AEs can guide clients through the buying process, increase the probability of closing big deals, and ultimately drive customer success and revenue growth.
