When I was an ROTC cadet in the late 80s, our cadre told us as new platoon leaders our most important administrative tool would be our skilcraft pens. I remember the day as platoon leader and company training officer, that our first PC showed up in the company orderly room, a 286 or 386 IIRC. It was at that time I noted a fundamental change in the officer corps. Up until that point, there was an over-arching concept called, “leadership,” and one skill under that umbrella was management. With widespread automated data processing, that became inverted and the officer corps appeared to stress management as the overarching umbrella, under which leadership became a subordinate skill. I guess leadership is harder to quantify and evaluate (unless you’re one of the ones being led.)
That’s a great observation that I witnessed as well.
