Adam Smith's business dictums from the 1800s no longer apply. That's the thinking behind management consultants James Champy and Michael Hammer's 1994 bestseller. Rigid divisions of labor — which once sped up productivity in fledgling corporate America — was now driving the sluggishness and lack of creativity holding firms back, the authors contend. They advocate for a radical redesign of the way companies process and organize their business, including regrouping multiple jobs into one. No wonder the book is credited with inspiring corporate downsizing in the 1990s. In the digital age, its insights still ring true.
