Craftsmen including IT professionals are distinguished by their tools. How sharp and ready for use they are, how handsome, handy and functional they are. Rusty, rough edged or downright broken tools are hallmarks of laxness in the art.
In the case of IT the tools are the person’s synthetic and analytic, even programming abilities. They are not the iron and the OS in current fancy, much like a fine and artfully handled trowel will raise buildings from a range of stones and bricks and mortar.
IT is in the science of the art.
