Here’s a EuroBusiness column stressing the benefits of combinational possibilities (PDF link); the synthesis of existing ideas to create new ideas.
Remember that someone put a trolley and a suitcase together and got a suitcase with wheels. Someone put a copier and a telephone together and got a fax machine. Someone put a bell and a clock together and got an alarm clock. Someone put a coin punch and a wine press together and we got books.
So the next time you wheel your suitcase or read a fax or a book you are benefiting from someone’s ingenuity in putting together a combination of ideas.
