Simple is excellent but needs to focus on viable metrics ...Simplicity needs to measure the things which really matter. This is different than emphasizing measurements need to be accurate. Measure what's truly important. Simple things that can be accurately and clearly measured. By asking ourselves the right questions we find an abundance of viable solutions.
If anyone needs ideas read Al Brooks. Make his ideas yours. Focus on using his ideas to answer the questions u have or know are the important questions. Apply his ideas and u will get new ideas. Your own ideas. In my experience this is necessary. To form our own questions and answer them ourselves. Many books have viable concepts. Fortunately it's difficult to see this.
This is directed to everyone. It's not intended to emphasize Brooks. Brooks allows me to suggest a path I know works without adding to what he says other than describing the big picture critically important essence of the problem. I hope this inspires and encourages everyone to give your effort your personal best.
