Which of the following is NOT a way to learn about the culture of a business?

Employee performance reviews focus primarily on assessing individual employee performance and contributions within the company. While these reviews can reflect the overall effectiveness of a workforce and may touch on aspects of culture indirectly (such as teamwork or alignment with company values), they do not directly provide insight into the broader cultural elements of the organization.

In contrast, the other options—corporate mission statements and official goals, observable business practices, and the stories people tell—are directly related to understanding the company's culture. Corporate mission statements articulate the organization's values and aspirations, while observable practices reflect how those values are enacted on a daily basis. Stories shared among employees often embody the organization's history, values, and norms, thus serving as rich cultural indicators. Therefore, focusing on employee performance reviews does not provide a clear or comprehensive understanding of the business culture compared to the other methods mentioned.
