This article on leading change highlights the need to prepare and suggests 4 P’s in that preparation:

Purpose – know what you want the company to look like after the transformation (and the most enlightening purpose involves more than just financial returns)

People – your best people for today might not be the best people for tomorrow. Be honest and realistic about who you need to reach your vision.

Paradox – some of your demands might seem to be at odds with each other. Look beyond that toward the final target and be ready to deal with ambiguity.

Persistence – change takes time. Prepare yourself and others for the journey, not just the destination.

Take a look at the article and see where you agree or disagree. Designing Leaders uses a change model that approaches change broadly, and this discussion seems to fill in some of the gaps. What do you think?
