A technologist is one employed to solve problems by the application of information technology. If you can't measure it then it can't be called engineering. -- I can measure software. I can provide measurements of algorithms. I can run a test client to measure maximum throughput or determine the maximum number of simultaneous clients a server can handle. As an engineer I can try to improve these measurements by modifying my software design. I can then measure the new design to determine if my changes actually did what I intended. – I don't think performance is only what they had in mind. Interesting, because my job title says I'm a technologist. When I'm doing what I call software engineering, I'm designing and implementing code to run in deeply software applications. I actually make things happen in real time in the real world. I solve engineering problems through information technology.
