What rings truer to me is that it's crazy how often building a tool or process, etc, eventually turns into people being able to make careers of just that thing because of all the spins and metaprocesses people will throw on top of or into it.
Git springs to mind for one, but (capital A) Agile definitely wins the championship.
Most teams or companies I've worked in have a git guru but it's far from all they do. It's the occasional stop by at that person's every so often for help with something that is outside the absolute basics.
Sometimes it’s just that by taking enough out, it becomes unclear and complicated. I “taught” eXtreme Programming to two of my own teams by showing them the book. Worked like a charm. I also participated in several “Agile” installs that failed despite training, meetings, demonstrations, etc. All because removing the “customer is in charge and developer is allowed to get the job done as they see fit” component made it complicated.
