The case study attached above is an interview with Samuel J$.$ Palmisano. Palmisano realized IBM needed to change. First read chapter $1$ describing what organizational development is and the concept of planned change. Second, read chapter $2$ and use it to answer the questions below on Case Study $1$: HBR $1$ Interview. After examining the four major theories of planned change, which theory best aligns with Palmisano's approach to change? Give examples from the case to support your answer. $(5-8$ sentences$).$ How did Palmisano adapt his approach to enact change at IBM? $($Link the terminology from the chapter readings and real$-$life examples in the case study. $3-5$ sentences$).$ Based on the readings, what suggestions would you give Palmisano if he had to be a "change agent" again at IBM? What could he do differently or improve upon based on the chapter readings and the examples in the case study? $(3-5$ sentences$).$
