Are SMART goals useful for programmers? [closed]

Question

Several organisations I know use SMART goals for their programmers. SMART is an acronym for Specific, Measurable, Achievable, Relevant and Time-Bound. They are fairly common in large corporations.

My own prior experience with SMART goals has not been all that positive. Have other programmers found them an effective way to measure performance? What are some examples of good SMART goals for programmers (if they exist).
