A colleague recently asked me which is better for driving needed performance: training or performance support (job aids, checklists, documentation, online help, and so forth). Research tells us that the answer is “it depends.” It’s like trying to decide whether board games, online games, or mobile games are better. Better for what? A board game will work best when people are in the same physical location. But you can play online games with people who aren’t in the same location. And finally, when you are waiting somewhere, playing mobile games may help pass the time.
