Move Fast & Break Your Sudoku
My COO is obsessed with Sudoku and last week she beat her personal time record at the expert level: 7 minutes and 31 seconds.
A 3 minute and 15 second difference from her previous record.
She explained the difference between this new record and her previous times was that she allowed herself to make far more mistakes than before (think 8 instead of 2).
The more mistakes she made the more she learned what not to do, testing her theories until all the numbers clicked.
What a cool (and maybe nerdy) way to prove that lean experimentation works.
