ABSTRACT
The proper design and implementation of agile metrics can add value and enable the agile way of developing software.
BOX 9.1 ANALOGY: DECIBELS
The human ear transforms sound waves into audio signals. When the sound wave intensity increases tenfold in strength, the response of the human ear goes up 1 point. When sound intensity increases a hundred times, the human ear registers strength of 2 points. The response is logarithmic. Sound level is measured in decibels, which are essentially logarithms of sound wave intensity.
