What issue is Selah attempting to address by asking about a vendor's history and existing clients?

When Selah inquires about a vendor's history and their existing clients, she is primarily focused on understanding the level of support that the vendor can provide. A vendor's established history and the reputation built through their previous and current client relationships can offer insights into how reliably they deliver support and service to their customers.

A vendor with a strong track record and a solid base of clients is more likely to have effective support systems in place, demonstrating that they are responsive to client needs and capable of resolving issues as they arise. If a vendor has a history of successful client engagements, it indicates that they have likely dealt with various challenges and have systems to provide assistance efficiently.

On the other hand, evaluating aspects such as the quality of products, financial stability, or innovation capacity involves different lines of inquiry. Quality of products would focus more on the specifications and performance metrics of their offerings. Financial stability could be assessed through their financial records and market performance, while innovation capacity would require a look into their research and development efforts and past innovations. Thus, by asking about a vendor's history and their existing clients, Selah is primarily gauging the vendor's ability to provide ongoing support based on their past performance and relationships.
