Recommended by Steve in context of Tech in MTSs review - as an example of how the incorporation of a new technology left challenges. Said I might not immediately see why he recommended it.
Read it, skimming parts that were details of mining. Had a lot of specifics I didn't need.
Old way of mining coal had everyone equally trained, and a very tight social system that worked well. It meant that the same miners worked together for years, with high degrees of trust and transparency.
New methods used larger teams, very little social support - and while those methods were brought over from engineering where they could work, in the dangerous, dark, underground mines, taking out the social support system creates problems.
They spend a lot of time in the details - but the basic takeaway is that you can't forget the human element.
