Before you finish your next automation script

An excellent article from Wall Street Journal about pitfalls of automation:

This philosophy traps people in a vicious cycle of de-skilling. By isolating them from hard work, it dulls their skills and increases the odds that they will make mistakes. When those mistakes happen, designers respond by seeking to further restrict people’s responsibilities—spurring a new round of de-skilling.

Something to consider when you hand over that new automation script to your network operations center.
