Answer to Question 1

C

Answer to Question 2

Because implementing a new ERP system involves so many different changes to jobs and processes users must have extensive training in the system using real data and examples. This training should extend throughout the project and beyond the go live as new functions are added and new employees are hired. Ironically, training is one of the first things to be cut when a project goes over budget. Besides delivering training with an instructor in a classroom face-to-face, it can be done via DVDs, videos, and on-line or using web-based technologies.
