How to Analyze Your Personal Productivity
The smartest way to improve any aspect of a business (sales, costs, customer satisfaction, etc.) is to measure the current results related to that aspect, use the data to infer a strategy that may improve performance, implement that strategy and measure again to determine whether we were right or not. Surely we will fail occasionally before finding the correct clue, but having actual data on which support our decision is critical. Build, measure and learn. This is the mantra of The Lean Startup entrepreneurship method, so fashionable lately.
