I love the point that the Train the Trainer approach might be ideal but is not always realistic - especially because I work with a lot of smaller teams who already have to wear a lot of hats. In addition to training, I often spend a lot of time helping set up and assisting with iterations then in longer term engagements to assist with the more complex components. It always also reassuring to hear about others struggling with encouraging leader engagement (rather than them just saying the right words).
