Final answer:
In a detailed vendor comparison, documentation volume is not a typical factor considered; rather, cost, capacity, and performance benchmarks are more critical in the decision-making process.
Step-by-step explanation:
A detailed vendor comparison normally includes various factors that can influence the decision-making process when selecting a vendor for products or services. However, documentation volume is typically not among these essential comparison points.
Important factors to compare would include the cost of a typical configuration, maximum number of workstations that can be supported, and the performance as shown by benchmark results. Documentation volume, while it might have some relevance in terms of understanding the product or service, is generally not a pivotal factor in the comparison of vendors for a purchasing decision.
However, one factor that would typically not be included in a detailed vendor comparison is the maximum number of workstations. This is because the maximum number of workstations is not usually a key consideration when comparing vendors, as it tends to be subjective and specific to the organization's needs.
Therefore the correct answer is A. documentation volume.
