"Lots of our people try to get good new product ideas from outsiders, but they are careful to keep it legal. I wonder though about something I ran into on a trip to Australia last fall. I met what our company people there called a professional espionage agent. He employs a network of stewards and air hostesses to gather tidbits of information overheard in the first-class compartments of international flights. Sells this information for over a million dollars a year! I wonder what suggestions I should put in a memo for employees to minimize the chances that our key new product information will be stolen by competitors."
