What the author of the article is advocating is to use a failing team member as a method of rallying support and cooperation from the rest of the team by publicly throwing them under the bus. This really is fairly effective, at least in the short term, and a large number of very successful leaders have used this practice well. Giving the rest of the team a common enemy and a 'mark' they need to make sure they stay ahead of is effective and commonly used in military training.

However, it's just morally awful and I doubt (hope?) it's not actually more effective than just building a team where you don't have to do this.

If an employee is consistently missing deadlines, it's the fault of whoever put that employee in that position - either the employee was mis-hired, the tasks given to the employee are not do-able with his skillset, he hasn't been given enough support to accomplish the task, etc. Criticizing in private is just as bad as in public here - you need to stop criticizing and fix the problem at the root cause!
