What type of reports might be included in external sources for business data?

Published company reports are indeed a key type of report included in external sources for business data. These reports, which might include annual reports, financial statements, and market analysis, provide valuable insights about a company's performance, strategic direction, and overall health. They are typically made available to the public, allowing stakeholders, potential investors, and competitors to gather relevant information about a company's operations and market position.

The other types of reports listed, such as internal employee performance reports, customer satisfaction surveys, and sales pitch presentations, primarily serve internal purposes or are generated from internal data. These reports are not typically considered external sources since they are not intended for public dissemination and do not reflect a broader perspective outside the organization. Consequently, they do not fulfill the criteria for external reports that contribute to a comprehensive view of the business landscape.
