Social Issues in Postmortems - by John Allspaw. Takeaway: “Although apparently technically focused, postmortems are inherently social events. Especially for events with significant consequences, there are incentives to direct attention towards some issues and away from others. When large losses incur attention of senior management the tenor and content of the postmortem may shift away from freewheeling discourse to a more closed ended, narrowly technical discussion. Postmortems may become “stage plays” intended to assert organizational control, ratify management decisions, or localize and truncate the inquiry into circumstances and contributors.”

How to Run HUGE Retrospectives Across Dozens of Teams in Multiple Time Zones - by Luke Hohmann. Takeaway: “[T]raditional approaches to retrospectives – assembling a group people in a room with one or more facilitators – are too costly, don’t scale, take far too long and fail to produce high-impact results. As a consequence, large organizations either skip retrospectives entirely or they relegate retrospectives to individual teams, which tragically limit their effectiveness in identifying and implementing enterprise changes that can profoundly improve performance. Over time, because individual teams are not obtaining material benefits from retrospectives, they stop doing them at all.” Using online games can be a less expensive option.
