The Truly Awful Idea Behind Buffett's $4.2B KraftHeinz Wipeout

``What is the problem with [Zero-Based Budgeting]? Like other management fads -- think about Six Sigma or Reengineering -- it focuses everyone too much on meeting internally imposed cost reduction targets. It encourages departments to compete on how much they can cut and ties bonuses to how well they meet their targets. And that works really well for any industry where customers have no choice but to buy your company's product and demand for that product never stops growing. While there may still be industries like that, food is not one of them.''
