The Engine That Could: Seventy-Five Years of Values-Driven Change at Cummins Engine Company
"[THE ENGINE THAT COULD] does the job well enough of charting  the company's ups and downs...But the real usefulness of the narrative is the way Cruikshank and Sicilia use the Cummins story as a framework for two broader themes...One is the inventor/patron relationship which can be discerned behind many business start-ups...The second theme which the book illustrates is the "staying power" that companies require to remain focused on basically the same products throughout their development."  --Financial Times, June 9, 1998
