Office Motivation Hack: Complete a Puzzle

Here's another fantastic Parent Hack that could work wonders in an office setting:

My 7 year-old son can be particularly stubborn and no matter howmuch we beg, plead, or reason with him, he stands his ground. SometimesI resort to bribery. He likes puzzles so I came up with puzzles to helphim do certain things.  It started the summer before Kindergarten -- healready knew how to tie his shoes, but claimed that he “forgot” howover the summer since he wore sandals all summer.  So I found a pair ofrunning shoes that he wanted online (I used Zappos.com)and printed out two full-sized  pictures.  One was in color and theother black and white.  I then decided that I wanted him to tie hisshoes for two weeks on his own before I would buy him the shoes hewanted so I cut the colored picture into the appropriate number of“puzzle” pieces.  Then every time he tied his shoes on his own heearned one piece that he could tape onto the black and white picture inthe correct spot.  When the puzzle was complete we ordered him hisshoes.

What are the goals for your office, and what is an appropriate reward when the goals are met?  Can you make a huge "puzzle" for your workers to complete as they reach appropriate milestones?
