From Software Metrics: Establishing a Company-Wide Program by Grady and Caswell: "A software metric defines a standard way of measuring some attribute of the software development process. For example, size, cost, defects, communications, difficulty, and environment are all attributes...."Kilo-lines of executable source" illustrate one metric for the size attribute. Metrics can be primitive (directly measurable or countable, such as counting lines of code) or computed (such as noncomment source statements/engineer/month)."

In addition to Charles' reply, note that there are numerous places on the Web where you can find the definitions of various types of metrics and how to apply them. If I may be so bold, I might recommend checking out the Metrics and Measures section of my Web site for some overall ideas. (I welcome any and all feedback and what is contained there.) There are also other sites that go into greater detail depending upon what you are looking for.

I mention this because you ask what the "implication" of a metric is and, if I am reading you correctly, that implication of a metric will totally depend upon the nature of the metric itself (which will be composed of one or more measures) and the means by which the metric is utilized.

Software metrics is the way to measure and manage the software application / product through out its life cycle, either periodic or event drive. During the life cycle we can manage the estimated size against the current, estimated effort against actual effort, study Defects, schedule variance etc.,
