In my career, I've gone from Waterfall, to XP, to Agile/Scrum methodologies.I've also spent some time doing V-Model. Personally, I'm looking forward to the switch to the "Screw It, This Works"™ methodology. Looking forward to the Addison-Wesley book series!

I work in a rather small company, but we are 100% WFH and we span quite a few timezones (From South America to South East Asia). Just yesterday I was summoned at 22:00 to un-fix a small previous fix that had been introduced earlier in the day and was affecting the production site... And the fix was meant "only" for test domains.
