Last week,
I shared some thoughts on the idea of "working managers". One thing I excluded was how the trend runs against what I perceive as the widely accepted preference for specialization. If your organization values management as a skill, wouldn't you want those who are good at management to focus a majority of their time in the role much in the same way you'd like your best programmers to spend most of their time writing code?
Of course, the other possibility is that "working managers" is just another example of how organizations find ways to waste time. If I think of the working manager as an equivalent to the programmer who spends half the week in listless meetings, perhaps my perspective on this topic will change.
