The Denis, Lamothe, and Langley (2001) article is not that recent, so it depends on how much work has been done on collective leadership as to whether can find anything more recent than this article. This is not important. The point of the exercise is to find another article dealing with leadership and strategic change in healthcare organizations. If that is not possible, find another article dealing with leadership and strategic change.
To that end it may be helpful to:Use the library databases to search on “leadership” and “strategic change model” and “health care” or “healthcare” to find related articles.Use Research report 9.1 to generate search terms, as previously suggested. The methods and research process sections have useful phrases that can be used for a literature search.You do not want to merely summarize the article. You want to indicate whether the article you found is consistent or inconsistent with the Denis,Lamothe and Langley (2001) findings. Then you want to discuss what these results, as a whole (both articles together), mean to leaders and managers in terms of being able to plan and conduct a change effort.
