I've often quoted this estimation trinity:
"Estimation, planning and tracking are an inseparable trinity. If you don't do one of them, you don't need the other two."
• If you don't estimate, you cannot plan and there is nothing to track. • If you do not plan, estimation and tracking is useless. • If you do not track, why should you estimate or plan?
Niels Malotaux
Said another way: if you don't care enough to plan your destination, and track your progress getting there, then any road will do, since anywhere will do.
