Dotted lines represent the triumph of pragmatism over purism.

I loved it when I was a contractor - I was brought in to do a job, I did that job with reference to defined interfaces, I had no legacy stuff to support and no dotted lines to service.

Life as a permie is different: I have many stacked 'main' jobs to do, and I have a load of other stuff to do too. I multi-task, so my concentration has to be switched many times in a day, and as a result my 'main' job of the day gets less of my time continuity is difficult to maintain. Still enjoyable: responsive to changing priorities, but perhaps less efficient in output.
