Why is it useful to conduct surveys of key employee attitudes before system implementation?

A) to provide information about the new system
B) to have a baseline for future comparisons
C) to solicit recommendations for changes
D) to create perception of employee involvement

Conducting surveys of key employee attitudes before system implementation provides a baseline for future comparisons. This allows for the evaluation of whether the new system has had a positive or negative impact on employee attitudes and overall satisfaction. Additionally, it can highlight areas where improvements may be needed to ensure the success of the system implementation. While the other options may also be benefits of conducting surveys, they are not as directly related to the purpose of establishing a baseline for comparison.
