Having two interviewers present during client interviews is valuable primarily because it allows for a second perspective and enhances the accuracy of information gathered. One interviewer can focus on engaging with the client, building rapport, and facilitating the conversation, while the other can take detailed notes and observe the client’s non-verbal cues. This dual approach helps to ensure that important points are not missed and can provide a more comprehensive understanding of the client's needs and preferences.

Additionally, having multiple interviewers can facilitate a more dynamic dialogue, allowing for clarifying questions or follow-ups based on the conversation flow. This collaborative method fosters an environment where both interviewers can share insights later, leading to a more thorough analysis of the client's input and better-informed design decisions.

The other options don't adequately address the primary benefit of having multiple interviewers. Speed may not be significantly improved, costs may not be reduced just by having an extra person, and while managing interruptions may be a consideration, it is not a primary reason for having two interviewers.
