Inflection point suggests that there are critical points in the history of an industry or an individual company that signal permanent and enduring change. The chapter describes inflection's applicability to retailing, and what signifies an inflection point as it relates to the retail business. Accelerators and disruptors describe the notion of disruptive change in the marketplace. Inflection points represent a significant and permanent shift in the retail market, and those changes can be the result of companies’ responses to accelerators and disruptors. The inflection point model would help the readers understand that the market movement can be affected if a significant response is made to accelerators or disruptors occurring in the market.
