This is an individual chapter of Theory of Constraints Handbook. Chapter Purpose: To provide a deeper understanding of the TOC organized buy-in process to overcome resistance to alter. We frequently find out that even great options do not offer themselves. If we wish to get the complete collaboration needed for a successful execution, we much better do a good task in buying people in. The chapter examines the different objections that people raise to a suggested modification and views them as layers that ought to be peeled in an orderly way. Better understanding of the layers of resistance to alter may help us prepare ways to provide modifications in a manner that promotes agreement, in addition to enhance our capability to deal with objections whenever we encounter them.
