A reminder, we have a companion ScoopIt site that is all about change tools & resources. Here's a sample. If you like it, feel free to follow us there as well as suggest good posts to enrich what we post as useful change management tools to share.
Reference from CMRsite.com ScoopIt:
It's been awhile since I've been able to track the original source of this helpful model that was listed without an attribution in the Worthington-Brighton Change Tools book in the late 90s.
Here's the source: The Managing Complex Change model was copyrighted by Dr. Mary Lippitt, founder and president of Enterprise Management, Ltd., in 1987.
Many experienced practitioners appreciate how it has categories for the many symptoms of ineffective change, which is why I think I've seen it at least a dozen times over the years.
