Measuring progress enables following achievements more systematically and objectively. Setting concrete goals and measuring the progress towards them helps to see whether one is on the right track and proceeding at the anticipated pace. Measuring progress also helps to track and solve problems faster when they occur.
When plans and expectations are not based on scenarios and hunches, but on real data on previous efforts, they become more realistic and probable to achieve.
