Explanation
The business analyst should do to gain the necessary buy-in and support from the sales team to ensure a solution meets the requirements is to ask questions to understand their needs and focus on shared goals.
Asking questions is an elicitation technique that allows the business analyst to gather information, clarify assumptions, or validate understanding from stakeholders. It can help the business analyst understand the sales team's doubts or concerns about the new tool, and address them with empathy or evidence. Focusing on shared goals is a collaboration technique that aligns stakeholders on a common vision or outcome for a project or initiative. It can help the business analyst show how the new tool will benefit the sales team and meet their expectations or needs. Presenting the pros and cons of the decision by using logic and facts may not be an effective way to gain buy-in and support from the sales team because it may not address their emotional or psychological barriers or resistance to change. Demonstrating expertise and clearly stating the decision is final may not be an effective way to gain buy-in and support from the sales team because it may not involve them in the decision-making process or respect their opinions or feedback.
