Whether the lead has sufficient buying power is the relevant information that the job title typically indicates about the lead to the sales rep. A lead is a prospect who has shown interest in the product or service that the sales rep offers. A job title is a designation or position that a person holds in an organization or company. A job title helps to indicate whether the lead has sufficient buying power, which means that they have the authority or influence to make a purchase decision or approve a budget for the product or service.

Sharing a customer success story is a powerful way to convince a contact to make an introduction to the decisionmaker, as it demonstrates the value and credibility of the sales rep's solution. A customer success story should include the following elements: the customer's challenge, the solution they implemented, and the results they achieved. The sales rep should also tailor the story to match the contact's industry, role, and pain points, and highlight how the solution can help them achieve their goals. By sharing a customer success story, the sales rep can create a sense of urgency and curiosity in the contact, and motivate them to introduce the sales rep to the decision maker who can benefit from the solution as well.

Stage velocity is the pace a deal moves from one stage to another in a sales pipeline. It is a measure of how quickly and efficiently a sales representative can move an opportunity from the initial contact to the final close. Stage velocity can help the sales representative to forecast more accurately, identify and remove any bottlenecks or obstacles, and optimize their sales process. The number of stages an opportunity must go through or the average length of a customer's contract are not the correct definitions of stage velocity, although they may affect it. The number of stages may vary depending on the complexity and size of the deal, and the average length of a customer's contract may depend on the type and value of the solution.

Key performance indicators (KPIs) are measures that can help the sales rep comprehensively assess theeffectiveness of their account management strategy. KPIs are quantifiable metrics that reflect how well the sales rep is achieving their account management goals and objectives, such as revenue growth, customer retention, customer satisfaction, cross-selling, upselling, etc. KPIs help to track progress, identify strengths and weaknesses, and improve performance.References:https://www.salesforce.com/resources/articles/account- management/#account-management-kpis

Expansion target is the best answer because it refers to the opportunity to sell more products or services to an existing customer who isgrowing their business or entering new markets. The sales rep should focus on understanding the customer's needs and goals in the new regions, and offer solutions that can help them achieve them. Efficiency target and growth target are not relevant to thisscenario, because they are related to the sales rep's own performance and objectives, not the customer's. Efficiency target is about improving the sales rep's productivity and effectiveness, while growth target is about acquiring new customers or increasing market share.
