I won't get into whether or not it's fair to call call "developers" "engineers", but I do make the distinction in the first paragraph that the article refers to software engineers. In addition, velocity, bug count, and lines of code are all software terms. I can't imagine anyone thinking this is referring to any other type of engineering.

Note that other types of engineers write code: CAD, CFD, FEM, etc. We don't develop software products, but we write code to pursue our goals.

Velocity? How is that a software term?

[schwarzmx]

It's a pretty well known term in agile software development.

Then the title should be changed.
