Last month's column was the first in a series about establishing a post-commissioning training program that provides ongoing "second-generation" training to help maintain optimum, long-term system performance and realize the full value of the commissioning process.

This month's column focuses on the factors that influence the decision to design and implement a training program, or to redesign an existing program that better serves the current and future training needs of the O&M staff. This "go/no go" decision is based on the perceived value of training and the expected ROI, of which are determined by examining the potential costs and benefits of training.
