What is pam on sistas?

As an AI language model, I do not have access to specific information about Sistas or any TV shows. However, from a general perspective, PAM (Product Assessment Matrix) is a tool used in marketing and product development to evaluate products or services against specific criteria such as price, quality, features, usability, and competition. It helps determine the strengths and weaknesses of a product and identify areas for improvement. It is possible that PAM is used in Sistas to evaluate products or services the characters are involved with.
