Final answer:
The company needs to assess the contracted salespeople's familiarity with SharePoint before sharing dashboards to ensure effective access and usage. Design elements are secondary, and age is not directly relevant.
Step-by-step explanation:
Before a company decides to share dashboards with contracted salespeople via SharePoint, the company must first determine the contracted salespeople's familiarity with SharePoint. This is crucial because the effectiveness of sharing these dashboards will largely depend on whether the salespeople can efficiently access and utilize them within SharePoint. Factors such as the optimal color scheme for the dashboards or the preferred font style are secondary design considerations, while the average age of the contracted salespeople is not directly relevant to their ability to use the platform.
